From 60342a6d1c83f93eb9117516b208c39f7ff4e58d Mon Sep 17 00:00:00 2001 From: Pratheesh Gangadhar Date: Wed, 21 Oct 2026 05:43:42 +0530 Subject: [PATCH 001/120] Add shared block infrastructure to the register allocator and static module Register allocator: - release a block's registers after its last data consumer, including values produced outside a loop and read inside it - keep pre-initialized loop values in their own register and support explicit loop accumulator bindings and exported loop results - route each consumer input from the output port it is wired to and refuse connections to ports that own no register - record register-pool exhaustion per block so validation can name it - reserve user-typed registers that blocks emit verbatim and report overlapping ones - give multi-result macros one destination register per output - keep 64-bit (two register) sources and outputs Static module and templates: - report allocation failures, pinned-register conflicts, unconnected required inputs, invalid port connections, loop/container boundary violations and macro arity mismatches at validation time - program CTPPR0 so c28 points at shared RAM when a block uses c28, and drive SPI controller CS pins to their idle level, at every entry into generated code - warn in the GUI when a GPO/GPI pad is shared or a GPO has two drivers - gate blocks that need a hardware widget on the device capability table - define TEMP_REG3/TEMP_REG4 (R26/R27) for macros - expand multi-line instructions in the simulator path New shared scripts: pru_reserved_names.js (clpru reserved identifiers), pru_spi_timing.js (SPI delay limits and IRAM budget), pru_device_caps.js (per-SoC hardware widgets), block_control_flow_data.js. --- .../common/block_control_flow_data.js | 33 + .../common/pru_blocks_static_module.syscfg.js | 767 +++++++++++++++- .../pru_blocks/common/pru_device_caps.js | 144 +++ .../pru_blocks/common/pru_reserved_names.js | 161 ++++ .../.meta/pru_blocks/common/pru_spi_timing.js | 153 ++++ .../pru_blocks/common/pru_syscfg.asm.xdt | 16 + .../pru_blocks/common/pru_syscfg.inc.xdt | 2 + .../pru_register_allocator.js | 834 +++++++++++++++++- 8 files changed, 2046 insertions(+), 64 deletions(-) create mode 100644 .metadata/sysconfig/.meta/pru_blocks/common/block_control_flow_data.js create mode 100644 .metadata/sysconfig/.meta/pru_blocks/common/pru_device_caps.js create mode 100644 .metadata/sysconfig/.meta/pru_blocks/common/pru_reserved_names.js create mode 100644 .metadata/sysconfig/.meta/pru_blocks/common/pru_spi_timing.js diff --git a/.metadata/sysconfig/.meta/pru_blocks/common/block_control_flow_data.js b/.metadata/sysconfig/.meta/pru_blocks/common/block_control_flow_data.js new file mode 100644 index 0000000..daaef9c --- /dev/null +++ b/.metadata/sysconfig/.meta/pru_blocks/common/block_control_flow_data.js @@ -0,0 +1,33 @@ +// Control-flow class ("sequential" or "continuous") of each block, used by the GUI pin-sharing check in +// pru_blocks_static_module: instances of one sequential module may share a two-way pad, and a GPO driven by +// two instances is flagged when either block is continuous.

The Pins summary and the Read by field are computed for you. + +**One driver per PRU-driven pin.** A GPO that a *PRU drives* pin listens on may be driven only by the blocks that talk to that device; any other block on that GPO, such as a SPI write sharing the clock, is an ERROR because the device counts its output as extra edges. Which blocks, per kind: the SSI, BiSS-C, EnDat and sigma-delta clocks accept only the reader block whose data pin is the device's data pin (SSI, BiSS-C or EnDat initiator, PDM microphone), shown in *Read by*; MDIO's MDC accepts an MDIO master whose MDIO pin is the device's; a SPI ADC's SCLK and MOSI are shared between chips so any SPI block may drive them, but its CS accepts only a SPI block whose CS pin is the device's; STEP/DIR and WS2812 accept the stepper, multi-axis or WS2812 block on that pad. A second block of the reader's own module pointing at a different data pin is foreign. With no matching block in the design a foreign block is a warning instead (it may be a hand-built generator). BiSS Line has no block in this tool, so it only warns when two or more blocks drive its MASTER pad. Two blocks reading one SSI, BiSS-C or EnDat encoder is also a warning: the second frame can start inside the encoder's monoflop time and is read as extra clocks. + +**Parameters.** Every model parameter is a typed field and is range-checked here, not discovered at run time. Parameters this block does not expose keep the model's own default (BiSS-C encoder keywords, SSI/EnDat initial clock level, MDIO register map, BiSS Line sensor data). + +**Simulation scope.** The in-tool JavaScript waveform preview does not attach Device Model blocks; TI pru-simulator does. +`; +} + +function getAIContext() { + return getLongDescription() + ` +## How to Configure (For AI/Scripting) + +\`\`\`javascript +const deviceModel = scripting.addModule("/pru_blocks/utils/device_model_block", {}, false); +const enc = deviceModel.addInstance(); +enc.$name = "Encoder_Model"; +enc.deviceKind = "ssi"; +enc.ssi_dataPin = 1; // device drives, the PRU reads +enc.ssi_clkPin = 0; // PRU drives +enc.ssi_bits = 25; +enc.ssi_position = 4321; +\`\`\` + +Field names are \`_\`; only the selected kind's fields apply.

If a tick +crosses several entries in one call (a multi-cycle instruction advanced the +clock past them), every crossed entry is applied in order and each is +recorded as an event. + +EXHAUSTION IS A FAULT +--------------------- +Running past the last entry — the waveform exhausted before the program +halted — raises a real fault, not a payload flag. Stimulus beyond the end of +the waveform is unspecified; a run that keeps executing on held inputs looks +green while proving nothing, so it must not be ignorable. The last value is +still HELD on the pins (that is what pull-ups and latches do), but the fault +stands. + +WIRE CONTRACT +------------- +Implements the TI pru-simulator ``DeviceBus`` device contract: ``tick`` +returns ``(drive_mask, drive_values)``, ``nets`` declares the driven pins +(push-pull: a stimulus source colliding with another driver is contention, +which the bus records as a fault rather than silently resolving), and +``time_driven = True`` because the player advances with the clock, not with +pin activity. + +Accepts both emitter shapes: the wrapped ``{"gpi_word_by_cycle": {...}}`` +form and the bare ``{cycle: value}`` map.

The block + * keeps the CONSERVATIVE range 0..63 (reading A): rows 64..511 are refused + * rather than aliased or invented.

R10, 2 bytes selects the + * row (R10.w0[5:0] row 0..63); then R2..R9 is the 32-byte row + * window. This block's write loads ONLY R2 from its INPUT port, + * so write is limited to BYTECOUNT 1..4: a longer XOUT + * would send stale R3..R9. ID 48 is the only path that programs the + * address; it is XOUT-only for data as well. + * 48 (0x30) — BS RAM read (XIN) as well as address + data write (XOUT). + * After the same 48/R10 address setup, XIN 48, &R2, BYTECOUNT + * returns the first BYTECOUNT bytes of the row (the XIN + * length is the byteCount config, not a hardcoded 32). Fig 6-49 assigns one ID per core; instruction + * direction selects read versus write. Decimal 30 (0x1E) is + * RTU_PRU's ID, and on PRU is FDB_Data (Table 6-100), so it + * must never be emitted by this PRU/TX_PRU block. XIN source + * window is likewise + * architecturally R2..R9 and at most 32 bytes. + * 49 (0x31) — BS RAM + SUM32 snoop (XOUT).

TRM Table 6-91 requires a 32 Byte write + * here; only R2 comes from INPUT, so the macro zero-fills R3..R9 + * rather than sending stale register contents. + * + * Per-core private: each PRU core has its own 2 KB (64 x 32 B). The memory + * is not shared between cores and not subject to spinlock/FIFO arbitration; + * determinacy comes from that privacy, not from a shared-mutex protocol. + * The simulator therefore keeps a per-Simulator (per-core) 64 x 32 B model, + * not a per-subsystem table like XFR2SPIN. + * + * Register windows are architectural (like BSWAP 0xA1/0xA2 and Stitch FIFO): + * R10 for the 2-byte address, R2..R9 for the up-to-32-byte data window. + * Declared via registerClobbers and rejected by validateBsRamGlobal if a + * live graph value would be overwritten, rather than pre-reserving them in + * the allocator. + * + * Core and device ID note: + * Device ID 48 is the PRU and TX_PRU base-mode mapping for both directions + * (Fig 6-49; Table 6-91).

Excludes arbitration and CRC for this slice; it does not flag stuff errors and does not check that SOF is still dominant at its sample point. TIMING: bit time is clkHz / (bitRateKbps * 1000) PRU cycles (200 for 1 Mbit/s and 400 for 500 kbit/s at 200 MHz); the sample point is samplePointPercent of the bit; the decoder hard-syncs on the SOF edge and then applies a soft resync (ISO 11898-1: recessive-to-dominant edges only, at most one per bit, armed after a recessive sample) whose correction is clamped to sjwCycles (rounded to the 3-cycle poll tick, default one tick). The destuff path costs exactly 10 PRU cycles on every path and the remainder of the bit is a cycle-counted 3-cycle poll loop, so sample-to-sample is exactly one bit time. Supported bit time is 41 to 20000 PRU cycles (sjwCycles = 3). Verified on the TI pru-simulator running the real clpru ELF at 200 and 400 cycles per bit (clean frame, per-bit jitter, oscillator drift, a phase error larger than SJW); NOT hardware validated. The block waits for the SOF edge and then runs for 32 destuffed bits, so it has no bounded peak cycle count: noOfCycles is -1 (unknown) and the generated OVERALL PEAK CYCLES header reads Unknown. BREAKING CHANGE: the old fixed 10-PRU-cycles-per-bit sampling (PRU clock / 10) is gone, and a saved .syscfg that lacks the new bitRateKbps, clkHz, samplePointPercent and sjwCycles fields now decodes at the defaults, 1 Mbit/s at 200 MHz = 200 cycles per bit. Dead zone: at the minimum configurations a late edge more than SJW + 2 cycles after nominal is ignored (the sample point does not move), and an early edge within the 10-cycle destuff path after the sample is ignored.

The text lists FDB_GEN_MODE_EN_BK0/BK1 + * and FDB_GEN_MODE_BYTE_EN in MII_G_RT_FDB_GEN_CFG2 as the enables, with no + * sentence that says "MII0/MII1 must be enabled/port-configured" as a + * prerequisite for this path. + * - Table 6-60 "Hardware Module Broadside ID Mapping" lists FDB IDs 30, + * 31, 35 as broadside peripherals reachable from PRU0/PRU1 (1 cycle per + * XFR), again without a footnote that ties ID availability to MII port + * state. Table 6-105 (Generic Mode Transfer Timing) describes the + * 2-cycle hazard between pattern/address/data XFR and the XIN 35 + * compare_result, without conditioning it on MII configuration. + * - The LUT/bridging mode section (6.4.11.2.3.7.2-3) IS explicitly driven + * by RX SOF and Ethernet framing and is, by construction, Ethernet-owned. + * That mode is left NOT BUILT by this block (see OUT OF SCOPE below). + * - The only place where MII_RT configuration and a broadside ID interact + * is the XFR2PSI shared pair 0x58/0x59 case (Table 6-60 + MII_G_RT_ICSS_G_CFG + * bit 9, modelled in xfr2psi_block.syscfg.js). That is a precedent for a + * cfg bit that lives in the same register block yet gates a DIFFERENT + * peripheral - it does not imply every cfg bit in MII_G_RT is MII-port- + * dependent. + * + * What the TRM does NOT say, and therefore what we do NOT claim: + * The TRM is silent on whether the FDB clock/reset or its generic-mode + * datapath are gated by the MII0/MII1 port-enable bits in MII_G_RT. No + * sentence proves independence, and no sentence proves dependence, and no + * second source settles it. + * + * Verdict recorded honestly: GO with explicit caveat - the TRM's generic-mode + * prose and broadside tables describe the access without listing MII port + * configuration as a prerequisite, so we proceed on that reading, but the TRM + * does not state independence in a single settling sentence and this has not + * been proven on silicon. The block is therefore delivered as + * "simulator-tested" at most, and its header and docs carry this caveat + * rather than a claim that the question is closed.

Every tick performs the same instruction sequence, so a + * tick is an exact number of PRU cycles (tickCycles() below) and a step + * period is an exact number of ticks. + * - Per axis a 32-bit phase accumulator (a DDA) adds a constant each tick; + * a carry out of the add is one step. The constant is + * round(2^32 * speed * tick / clkHz), computed at generation time. + * - Synchronized start: with syncEnable the accumulators are pre-loaded to + * 2^32 - inc, so EVERY axis carries on the very first tick and the first + * step of all axes is one single `or R30, R30, mask` write - the same + * cycle, not "close together". + * - Step bits of all axes rise in one 32-bit write and fall in one 32-bit + * write, so pulse width is identical on every axis. + * - E-Stop: the GPI pin is sampled once per tick; when asserted every pin + * this block drives is cleared, status bit 7 is latched and the core + * HALTs. Worst-case latency is one tick plus the clamp (measured). + * - Constant speed per axis, steps counted down to targetSteps. + * + * What it does NOT do (the previous macro text claimed all of these): + * - No trapezoidal acceleration: accel0..3 are accepted but ignored. + * - No IEP timebase: timing is the fixed-length tick above, not the IEP. + * - No home/limit switch handling: homeSwPin/limitPPin/limitNPin are ignored. + * - No command-queue consumption and no underrun detection: targets are the + * static values below; dmemBase is ignored (state lives in registers). + * + * Registers: the macro uses R18..R25 (acc/remaining per axis, two per axis) + * plus TEMP_REG1..TEMP_REG4.

NOT A CERTIFIED SAFETY FUNCTION + +**WARNING: This PRU block is NOT a certified safety function.** It is only a +monitor / pre-filter that feeds a certified safety path (e.g. a safety PLC, +safety relay, or qualified MCU safety island). Do NOT use its output as the +sole safety decision. A certified safety function requires qualified hardware, +systematic capability (e.g. IEC 61508 / ISO 13849) and independent validation +beyond what the PRU No-Code simulator can prove. Keep this disclaimer with +any design that instantiates the block and preserve it in generated docs. + +### Purpose +Monitors two normally-high safety channels (e.g. OSSD outputs from a light +curtain). Tolerates short OSSD test pulses (typically 100 us to 1 ms, +20k-200k PRU cycles at 200 MHz) while treating longer LOW as a genuine trip. +Detects channel disagreement persisting beyond a bounded discrepancy timer +as a fault. Outputs a status word for the certified safety path to consume. + +### How it works (2-TEMP_REG pattern) +The block uses **TEMP_REG1 (R28)** and **TEMP_REG2 (R29)** as the two +scratch registers: + +* **Pulse-width discrimination (TEMP_REG2):** when a channel goes LOW the + firmware counts LOW cycles in TEMP_REG2 and compares against OSSD_MAX. + Width <= OSSD_MAX is tolerated as an OSSD test pulse; width > OSSD_MAX + is classified as a trip. +* **Bounded discrepancy timer (TEMP_REG1):** when channels disagree + (A != B) a countdown of DISC_CYCLES is started in TEMP_REG1. If + agreement returns before expiry the event is judged by the pulse width; + if the timer expires while still disagreeing a discrepancy fault is + raised. +* The two timers run together: a short disagreeing pulse within both + limits is accepted as an OSSD pulse; a long disagreement or a long + LOW beyond OSSD_MAX drives STATUS non-zero. + +### Output (STATUS register) +* \`0\` ? SAFE: both channels HIGH, or a tolerable OSSD pulse was seen + and channels have re-agreed within the windows. +* \`1\` ? TRIP: prolonged LOW beyond OSSD_MAX (genuine demand). +* \`2\` ? DISCREPANCY_FAULT: channels disagreed longer than DISC_CYCLES. + +The monitor is single-pass: each invocation samples, applies the timers, +and writes STATUS. For continuous monitoring place it in a loop or poll +it from the main sequence. + +### Configuration +* **CH_A / CH_B** ? the two GPI pins (R31 bits) carrying the safety channels. +* **Discrepancy cycles** ? bounded window during which disagreement is tolerated. +* **OSSD max cycles** ? longest LOW still treated as an OSSD test pulse. +* **Status register** ? 32-bit PRU register receiving 0/1/2. + +### Generated assembly +Uses only base PRU instructions (qbbs/qbbc, ldi, add, sub, qbgt, qbeq) and +the two TEMP_REGs, so the headless simulator and the TI pru-simulator +execute the same binary. No MULL/XIN/XOUT. + +### Residual gaps +* Exact PRU cycle cost of the counting loops is not hardware-validated; + thresholds should be characterised on silicon and margined (see + dual-oracle method). +* The block does not implement debouncing beyond the two timers; external + filtering may be needed for noisy wiring. +* Not certified: see warning above. + +### Simulating +Use Simulation Settings (device mode \`ossd\` on the two pins) or drive +R31 via the Python model \`perif/ossd_emitter.DualOssdEmitter\` and the +independent oracle \`perif/buscosim.decode_ossd\`.

Each call sorts its edges once into an event list (the duties are the same for every period of the call); each period then reads the IEP counter once per poll iteration, compares it with the next event time and writes R30 when that time is reached. Edge times in IEP counts from the period start: high sides on at DEADTIME, high-off at min(duty, PERIOD) - DEADTIME, low-on at duty + DEADTIME, the sample strobe at PERIOD/2, all off at PERIOD. A high side stays off when its duty is at or below 2 x DEADTIME (its on-time, duty - 2 x DEADTIME, would be zero or less); a low side stays off when duty >= PERIOD - DEADTIME, and the low side of a leg at duty 0 turns on with the high sides; duties above the period are limited to the period. Dead time is never a busy-wait: it exists only as event times. Nominally both devices of a half bridge are off for 2 x DEADTIME counts, from the ideal high-off (duty - DEADTIME) to the ideal low-on (duty + DEADTIME). The delivered gap can be shorter when a late high-off bunches with an on-time low-on; the smallest gaps observed are about 8 counts at DEADTIME 10 and 16 at DEADTIME 20 (for example duties 424, 424, 444 at PERIOD 800, and 4, 4, 44 at PERIOD 400 with DEADTIME 20). This minimum is an observed value pinned by tests/test_three_phase_scheduling.py, not a guarantee; the two devices are never on together. Edges with the same count change in one R30 write. Timing in cycles (= IEP counts): one poll iteration W = 4 (lbco of CNT + qbgt), counter sample to the R30 write X = 5, write to the next write when that edge is already due X2 = 8. An edge is never early; an isolated edge is late by at most W + X = 9 counts, and the k-th edge of a cluster of single-edge writes by at most W + X + (k-1) x X2. A write that changes several pins at once (coincident edges, clamped legs) goes through an escape token and takes up to 32 cycles to dispatch; the per-kind costs are in tests/test_three_phase_scheduling.py. The strobe rises at PERIOD/2 under the same bound and is one poll iteration (4 cycles) wide. DEADTIME is an 8-bit immediate (at most 255). The macro owns IEP GLOBAL_CFG, CMP_CFG, CMP0, CNT and CMP_STATUS for the period (CMP0 flags the period end without resetting the counter, so a late edge is never lost), then disables CMP0 before returning. By default one call emits one period. Set Period count to N (1..2147483647) to emit N periods in one call: each period restarts the IEP counter and is the same waveform, edge for edge, as one single-period call, and compare events are disabled after the last. Consecutive periods are separated by 32 cycles (a back-to-back pair of single-period calls is separated by 182 because each call sorts its edges again and re-programs the IEP); the final return costs 2 cycles more than a single-period call (period decrement and branch), all after the last all-off edge. At small PERIOD with duties near PERIOD the late edges can land after the nominal period end (PERIOD 64, DEADTIME 1: an edge up to 77 counts late, an effective period of about 126 counts). The generated macro is about 985 instructions per inlined instance, roughly a third of a 3072-instruction instruction RAM; the single-period and the counted macro are separate bodies. Conservative instruction bound scales with N.\n\nTiming restrictions: this is a software block and its timing is not hardware-exact. (1) Dead time is nominally 2 x DEADTIME. The delivered minimum measured is about 8 counts at DEADTIME 10 and about 16 at DEADTIME 20, when a late high-off clusters with an on-time low-on. No overlap was seen in about 2000 configurations. It is an observed value pinned by tests, not a guaranteed minimum. (2) Single-edge writes are up to 8 counts late (W + X = 9 bound). Edges written together (coincident edges, clamped legs) are about 10 to 36 counts late in the test cases, against the 12-count budget of the single-edge path; example: PERIOD 800, DEADTIME 10, duties 400/400/400 gives low-ons 31 counts late. (3) This applies to the software block.

Submission + * is the XOUT 0x72 itself; firmware must not expect a separate trigger write. + * No hardware ring completion: hardware does not signal completion via an + * interrupt or a "done" bit that self-clears on ring wrap. Firmware polls + * tr_rsrc_busy / tr_rscr_fifo_occ / tr_rsrc_wrt_ptr via XIN 0x71 (status op) + * to observe progress. The simulator's drain (Simulator.XFR2TR_DRAIN_PERIOD_CYCLES) + * is a pacing model, not a hardware timing claim.

Larger + * values truncate in hardware; this block refuses them at build time instead + * of silently aliasing inside the window. Furthermore, the source TR list + * (tr_msrc_base) and the destination ring (tr_rsrc_base) must reside inside + * PRU_ICSSG Shared RAM / Data RAM2 — the only RAM the RTU_PRU local copy + * engine can address without a system-level path. In the local view + * (SPRACJ8 Migration Guide / SPRUIM2J local map) Shared Data RAM 2 starts at + * 0x0001_0000; the simulator's SMEM models 64 KB there (0x00010000-0x0001FFFF + * on AM64x/AM243x). Bases outside that window, or bases whose + * base+entries*trSize extent would leave the window (or exceed the 4 KB + * source-TR ceiling, gap 2), are build errors. + * + * 4 KB source-TR ceiling (gap 2): the source TR list that the ring + * copies from is capped at 4 KB (4096 bytes). Table 6-112 has no register + * that carries a source-list length — the only length register is + * tr_rsrc_nums, which sizes the DESTINATION ring (1..4096 entries) and is a + * completely separate object from the SOURCE list the 4 KB ceiling + * constrains.

Edge times in IEP counts from the period start: high sides on at DEADTIME, high-off at min(duty, PERIOD) - DEADTIME, low-on at duty + DEADTIME, the sample strobe at PERIOD/2, all off at PERIOD. A high side stays off when its duty is at or below 2 x DEADTIME (its on-time, duty - 2 x DEADTIME, would be zero or less); a low side stays off when duty >= PERIOD - DEADTIME, and the low side of a leg at duty 0 turns on with the high sides; duties above the period are limited to the period. Dead time is never a busy-wait: it exists only as event times. Nominally both devices of a half bridge are off for 2 x DEADTIME counts, from the ideal high-off (duty - DEADTIME) to the ideal low-on (duty + DEADTIME). The delivered gap can be shorter when a late high-off bunches with an on-time low-on; the smallest gaps observed are about 8 counts at DEADTIME 10 and 16 at DEADTIME 20 (for example duties 424, 424, 444 at PERIOD 800, and 4, 4, 44 at PERIOD 400 with DEADTIME 20).

The strobe rises at PERIOD/2 under the same bound and is one poll iteration (4 cycles) wide. DEADTIME is an 8-bit immediate (at most 255). The macro owns IEP GLOBAL_CFG, CMP_CFG, CMP0, CNT and CMP_STATUS for the period (CMP0 flags the period end without resetting the counter, so a late edge is never lost), then disables CMP0 before returning. By default one call emits one period. Set Period count to N (1..2147483647) to emit N periods in one call: each period restarts the IEP counter and is the same waveform, edge for edge, as one single-period call, and compare events are disabled after the last. Consecutive periods are separated by 32 cycles (a back-to-back pair of single-period calls is separated by 182 because each call sorts its edges again and re-programs the IEP); the final return costs 2 cycles more than a single-period call (period decrement and branch), all after the last all-off edge. At small PERIOD with duties near PERIOD the late edges can land after the nominal period end (PERIOD 64, DEADTIME 1: an edge up to 77 counts late, an effective period of about 126 counts). The generated macro is about 985 instructions per inlined instance, roughly a third of a 3072-instruction instruction RAM; the single-period and the counted macro are separate bodies.

It is an observed value pinned by tests, not a guaranteed minimum. (2) Single-edge writes are up to 8 counts late (W + X = 9 bound). Edges written together (coincident edges, clamped legs) are about 10 to 36 counts late in the test cases, against the 12-count budget of the single-edge path; example: PERIOD 800, DEADTIME 10, duties 400/400/400 gives low-ons 31 counts late. (3) This applies to the software block.

Set Period count to N (1..2147483647) to emit N periods in one call: each period restarts the IEP counter and is the same waveform, edge for edge, as one single-period call, and compare events are disabled after the last. Consecutive periods are separated by 32 cycles (a back-to-back pair of single-period calls is separated by 182 because each call sorts its edges again and re-programs the IEP); the final return costs 2 cycles more than a single-period call (period decrement and branch), all after the last all-off edge. At small PERIOD with duties near PERIOD the late edges can land after the nominal period end (PERIOD 64, DEADTIME 1: an edge up to 77 counts late, an effective period of about 126 counts). The generated macro is about 985 instructions per inlined instance, roughly a third of a 3072-instruction instruction RAM; the single-period and the counted macro are separate bodies. Conservative instruction bound scales with N.\n\nTiming restrictions: this is a software block and its timing is not hardware-exact. (1) Dead time is nominally 2 x DEADTIME. The delivered minimum measured is about 8 counts at DEADTIME 10 and about 16 at DEADTIME 20, when a late high-off clusters with an on-time low-on. No overlap was seen in about 2000 configurations. It is an observed value pinned by tests, not a guaranteed minimum. (2) Single-edge writes are up to 8 counts late (W + X = 9 bound). Edges written together (coincident edges, clamped legs) are about 10 to 36 counts late in the test cases, against the 12-count budget of the single-edge path; example: PERIOD 800, DEADTIME 10, duties 400/400/400 gives low-ons 31 counts late. (3) This applies to the software block. ICSS-M on AM261x has no PWM module; on AM243x/AM64x the ICSSG hardware PWM module (not covered by this block) is the better fit when dead time must be a guaranteed minimum.", uiView: "graph", config: [ diff --git a/scripts/check_block_docs.js b/scripts/check_block_docs.js deleted file mode 100644 index b9b9e5c..0000000 --- a/scripts/check_block_docs.js +++ /dev/null @@ -1,41 +0,0 @@ -#!/usr/bin/env node -// SPDX-License-Identifier: BSD-3-Clause -// CI gate: regenerates docs/block-reference and fails on any diff. -// Usage: node scripts/check_block_docs.js -'use strict'; -const { execSync, spawnSync } = require('child_process'); -const path = require('path'); - -const ROOT = path.join(__dirname, '..'); - -function run(cmd, opts = {}) { - console.log(`> ${cmd}`); - execSync(cmd, { stdio: 'inherit', cwd: ROOT, ...opts }); -} - -try { - run('node build_block_docs.js'); -} catch (e) { - console.error('check_block_docs: build_block_docs.js failed'); - process.exit(e.status || 1); -} - -// Use git diff to detect drift. --exit-code returns 1 when diff found. -const result = spawnSync('git', ['diff', '--exit-code', '--', 'docs/block-reference/'], { - cwd: ROOT, - stdio: 'inherit', -}); -if (result.status === 0) { - console.log('check_block_docs: PASS - docs/block-reference is up to date.'); - process.exit(0); -} else if (result.status === 1) { - console.error('check_block_docs: FAIL - docs/block-reference is stale.

RES holds the raw telegram (MSB = start bit); the position is LSB first on the wire, so the caller reverses the position field (as TI's driver does).\n\nPINS: one RS-485 transceiver per encoder: CLOCK out on one R30 bit, DATA driven through the transceiver driver from DATA_TX (R30) with its driver enable on DATA_EN (R30, DE = 1 only during the lead-in and the mode command), and the receiver output on DATA_RX (R31). TI's EnDat receiver uses the same split (pins endat_out, endat_out_en, endat_in). A PRU pad is either an input or an output, so TX, EN and RX must be different pad indices.\n\nSTAGED SCOPE (NOT implemented): other mode commands (parameters, memory area selection, reset, test values), additional data 1/2 and the EnDat 2.2 command supplement (MRS code), telegrams longer than 32 bits (needs a second accumulator register), propagation-delay compensation for clock rates above 2 MHz (requires IEP timestamping).\n\nPeripheral resources (selection rule): the hard EnDat peripheral (PRU-ICSSG three-channel peripheral interface) is preferred when available and correctly pinned; fallback is bit-banged PRU via an RS-485 transceiver - the staged PRU initiator consumes zero dedicated peripheral instances (no UART/SPI/IEP required in fallback). All four pins must sit on the same PRU-ICSSG slice through pinmux (AM64x/AM243x/AM261x). Isolation: the owning PRU slice must be the only master driving CLK_PIN, DATA_TX_PIN and DATA_EN_PIN during a telegram. Concurrent workload: the transfer is a busy-wait delay-loop sequence; the PRU cannot service other blocks mid-telegram (budget documented in noOfCycles). Deterministic timing: every clock half-period is a calibrated delay loop (halfPeriodCycles); at 200 MHz PRU, halfPeriodCycles=25 gives ~1.9 MHz, and trecCycles=1000 gives 10 us of recovery. BOM/part: one RS-485 transceiver with driver enable per encoder channel (e.g. SN65HVD / THVD class), termination per the EnDat cable spec. Simulator validation: the real clpru ELF of a one-block design runs on TI pru-simulator in a closed loop against pru-simulator's pru_io/endat_encoder.py through pru_io/rs485_transceiver.py (tests/test_endat_framing.py); EnDat is not yet selectable in the gmake sim front door (ported:false).

Turnaround time (idle before TX-to-RX or RX-to-TX switch) is configurable as a delay loop count.\n\n` + + `Framing modes:\n` + + `- MODBUS_RTU: address (1B) + function (1B) + data (0-252B) + CRC16 (2B, poly 0x8005, big-endian). Slave address match filter.

DMX512 uses no CRC.

Frames exceeding slotBytes are truncated or split across multiple slots with a continuation flag. The host signals new frames by updating the ring write pointer; the PRU polls the host-to-PRU queue (from mailbox) for TX commands (address+payload to send).\n\n` + + `Timeout: configurable inter-byte timeout (delay loops between consecutive bytes). If inter-byte gap exceeds timeout, the frame-in-progress is discarded and the bus is released.\n\n` + + `Bus collision: after TX, read back the echoed data on the RX line.

Requires the R30 pin for DE/RE, the ENDAT RX channel for receive, and the ENDAT TX channel for transmit. Pinmux: the RS-485 DE/RE pin must be on a PRU R30 bit routed through PRU-ICSSG pinmux. Isolation: single PRU slice owns the UART channel and direction pin during the full exchange. Deterministic timing: each byte at a given baud rate is handled by the ENDAT hardware; framing/turnaround uses calibrated delay loops. BOM: an RS-485 transceiver (e.g. THVD1450, SN65HVD72) with DE/RE tied to the designated R30 pin. Current maturity: metadata-only.

The silence watchdog is a 3-cycle countdown loop that is + * restarted after every received character; when it reaches zero without a + * new character starting, the frame boundary is declared.

Its CRC16 path is MSB-first non-reflected + * (LSR crcInit,8 / table over the high byte). Modbus RTU requires the + * reflected variant (0xA001 reflection of 0x8005, init 0xFFFF, LSB-first + * update over the LOW byte).

Character reception uses + the same per-bit valid-flag polling as \`uart_rx\`. Response transmission is + owned by \`uart_tx\` block instances downstream — this block is the RX + delimiting half. +2. **Reception** — bytes are appended to a 256-byte frame buffer in DMEM + (reserved by a paired Memory Variable block using \`bufferSymbol\`). +3. **Silence watchdog** — 3 cycles per iteration; 3.5 char times = 38.5 bit + times (11-bit RTU characters). Idle line (no frame started) keeps + listening. +4. **CRC-16** — table-driven reflected 0xA001 / init 0xFFFF, over the + length−2 payload. Shifts, XORs and LBBO only: the PRU has no MULL, and none + is needed. \`crc_block\` was checked first: its CRC16 path is MSB-first + non-reflected and cannot produce Modbus CRC values, so this block ships + its own reflected table through the same lutName mechanism. +5. **Address filter** — frame accepted if byte 0 equals \`slaveAddress\` or 0 + (broadcast). + +### Result register (output1, 4 bytes) +| Field | Meaning | +|-------|---------| +| b0 | status: 0 = OK, 1 = CRC error, 2 = address mismatch, 3 = frame too short (< 4 bytes) | +| b1 | frame length in bytes (address + PDU + 2 CRC bytes) | +| w2 | computed CRC-16 (little-endian in b2/b3, matching on-wire order) | + +Frames longer than 255 bytes drop the excess bytes; the truncation then fails +CRC and reports status 1. The block **blocks** until a frame is delimited +(it waits for silence), exactly like \`uart_rx\` waits for a character. + +### Dependencies and seams (stated honestly) +- **RS-485 direction control does not exist yet.** This block does not depend + on it and does not touch a direction pin. Seam: drive the transceiver DE/RE + pin from PRU GPO blocks around response transmission when that hardware is + present. +- **Frame buffer:** add a Memory Variable block with \`labelName\` = + \`bufferSymbol\`, 256 bytes, \`.udmem\`. The linker resolves the label. +- **CRC table:** emitted automatically (512 bytes) via the block's lutName in + \`.initdmem\`; multiple framer instances each emit their own table. +- **Pre-response gap:** the Modbus requirement to wait 3.5 character times + before transmitting a response can be met with a Delay block configured + from the same \`silenceTicks\` value. + +### Timing +- Watchdog granularity: 3 PRU cycles (poll + decrement + branch). +- Example defaults (200 MHz PRU, 115200 baud): bit = 1736 cycles, silence = + 66,736 cycles = 22246 watchdog iterations ≈ 333.7 µs measured at + cycle granularity. +- CRC: ~13 cycles per byte (two LDI32 bases, LBBO, shift/XOR update). +- The block's \`noOfCycles\` reports only the deterministic init portion; the + reception/wait phase is inherently blocking (like \`uart_rx\`). + +### Register budget +TEMP_REG1 / TEMP_REG2 only (2-TEMP allocator pattern) plus the allocated +frame result register. No MULL anywhere; all scaling is done at generation +time or with shifts. + +### What is NOT claimed +- No pru-simulator co-simulation of this block yet — the evidence gate for + this revision is a clean clpru assembly of the generated macro (see + \`scripts/verify_modbus_build.js\`) plus a JS-side check of the generated + CRC table against the bitwise reference. +- No TX-side framing (CRC append + gap enforcement) inside this block; build + it from uart_tx + crc arithmetic downstream, or wait for a TX framer. +`; +} + +function getAIContext() { + return getLongDescription() + ` +## How to Configure (For AI/Scripting) + +### Adding an Instance + +\`\`\`javascript +const modbus = scripting.addModule("/pru_blocks/application_specific/modbus_rtu_framer", {}, false); +const framer1 = modbus.addInstance(); +\`\`\` + +### Configuration Parameters + +| Parameter | Type | Valid Values | Default | Description | +|-----------|------|--------------|---------|-------------| +| slaveAddress | Integer | 0-247 | 1 | This station's Modbus address (0 accepts broadcast) | +| baudRate | Integer | >0, clock-divisible | 115200 | Baud rate; ENDAT clock must divide by baud*oversample | +| pruClockMhz | Integer | 192, 200 | 200 | PRU core clock used for the silence measurement | +| clockSource | Integer | 0, 1 | 0 | ENDAT RX clock: 0 = 192 MHz UART_CLK, 1 = 200 MHz CORE_CLK (must match paired uart blocks) | +| channel | Integer | 0, 1, 2 | 2 | ENDAT channel (must match paired uart blocks) | +| oversampleSize | Integer | 0, 1, 3, 7 | 7 | Oversample encoding (0=1x, 1=2x, 3=4x, 7=8x — same encoding as uart_rx: 7 means 8x) | +| bufferSymbol | String | identifier | "modbus_rtu_frame_buf" | Label of the 256-byte .udmem frame buffer (Memory Variable block) | +| lutMemoryLocation | String | "dmem", "smem" | "dmem" | Where the 512-byte CRC table is placed | + +### Required companion blocks +1. **Memory Variable** with \`labelName\` = \`bufferSymbol\`, \`sizeInBytes\` = 256, + section \`.udmem\` — the frame buffer this macro writes via SBBO. +2. **uart_tx instances** for the response path (character layer TX). +3. **Loop block** if you want continuous frame reception. + +### Example + +\`\`\`javascript +framer1.$name = "MODBUS_FRAMER_0"; +framer1.slaveAddress = 17; +framer1.baudRate = 115200; +framer1.pruClockMhz = 200; +framer1.clockSource = 0; +framer1.channel = 2; +framer1.oversampleSize = 7; // 8x oversampling +framer1.bufferSymbol = "modbus_rx_frame_buf"; +\`\`\` + +### Connecting + +\`\`\`javascript +// Result register (status/length/CRC) to downstream consumers +scripting.connect(framer1, "output1", status_consumer, "input1"); +// Control flow +scripting.connect(prev_block, "next", framer1, "prev"); +scripting.connect(framer1, "next", next_block, "prev"); +\`\`\` + +### Important Notes +1.

Rename the display names of the data handling, program control, PRU I/O and utility blocks that did not follow it; the config names, and so saved designs, are unchanged. Detail that no longer fits in a name moves to the field's description. The FDB acknowledgement error names the renamed box, the SPI ADC sequencer's computed constant count is hidden like every other block's, and the MDIO long description no longer writes R, which renders as an HTML tag. --- .../data_handling/bs_ram_block.syscfg.js | 8 +++---- .../data_handling/bswap_block.syscfg.js | 4 ++-- .../data_handling/stitch_fifo_block.syscfg.js | 6 ++--- .../data_handling/sum32_block.syscfg.js | 4 ++-- .../data_handling/svpwm_block.syscfg.js | 4 ++-- .../trigger_router_block.syscfg.js | 8 +++---- .../program_control/event_block.syscfg.js | 6 ++--- .../can_classic_decoder_block.syscfg.js | 10 ++++----- .../pru_io_blocks/capture_block.syscfg.js | 2 +- .../pru_io_blocks/counter_block.syscfg.js | 4 ++-- .../pru_io_blocks/dshot_block.syscfg.js | 4 ++-- .../encoder_speed_block.syscfg.js | 4 ++-- .../pru_io_blocks/fdb_gp_ram_block.syscfg.js | 22 +++++++++---------- .../pru_io_blocks/hall_block.syscfg.js | 10 ++++----- .../pru_io_blocks/i2c_block.syscfg.js | 10 ++++----- .../i3c_sdr_initiator_block.syscfg.js | 8 +++---- .../pru_io_blocks/mailbox_block.syscfg.js | 12 +++++----- .../pru_io_blocks/manchester_block.syscfg.js | 10 ++++----- .../pru_io_blocks/mdio_master_block.syscfg.js | 16 +++++++------- .../multi_axis_motion_block.syscfg.js | 18 +++++++-------- .../pru_io_blocks/onewire_block.syscfg.js | 8 +++---- .../parallel_bus_block.syscfg.js | 12 +++++----- .../pru_io_blocks/pdm_block.syscfg.js | 12 +++++----- .../pru_io_blocks/pru_spad_block.syscfg.js | 12 +++++----- .../pru_io_blocks/pwm_block.syscfg.js | 10 ++++----- .../pru_io_blocks/quadrature_block.syscfg.js | 12 +++++----- .../pru_io_blocks/queue_empty_block.syscfg.js | 2 +- .../safety_dual_monitor_block.syscfg.js | 10 ++++----- .../pru_io_blocks/sent_block.syscfg.js | 10 ++++----- .../pru_io_blocks/serdes_block.syscfg.js | 18 +++++++-------- .../pru_io_blocks/servo_block.syscfg.js | 8 +++---- .../spi_adc_sequencer_block.syscfg.js | 7 +++--- .../pru_io_blocks/stepper_block.syscfg.js | 6 ++--- .../three_phase_pwm_block.syscfg.js | 22 +++++++++---------- .../pru_io_blocks/ws2812_block.syscfg.js | 4 ++-- .../pru_io_blocks/xfr2psi_block.syscfg.js | 20 ++++++++--------- .../pru_io_blocks/xfr2spin_block.syscfg.js | 4 ++-- .../pru_blocks/utils/iep_block.syscfg.js | 4 ++-- .../utils/logic_analyzer_block.syscfg.js | 4 ++-- scripts/sim/test_fdb.js | 2 +- 40 files changed, 179 insertions(+), 178 deletions(-) diff --git a/.metadata/sysconfig/.meta/pru_blocks/data_handling/bs_ram_block.syscfg.js b/.metadata/sysconfig/.meta/pru_blocks/data_handling/bs_ram_block.syscfg.js index 0d4710a..cad2962 100644 --- a/.metadata/sysconfig/.meta/pru_blocks/data_handling/bs_ram_block.syscfg.js +++ b/.metadata/sysconfig/.meta/pru_blocks/data_handling/bs_ram_block.syscfg.js @@ -297,10 +297,10 @@ const bsRamModule = { { name: "read", displayName: "Read (XIN 48, &R2, Bytes)" }, { name: "snoop_write", displayName: "Snoop write (XOUT 49, BS RAM+SUM32)" } ] }, - { name: "rowAddress", displayName: "Row address (0..63)", default: 0, description: "BS RAM row 0..63 (2KB = 64 x 32B, TRM p.624).

RES holds the raw telegram (MSB = start bit); the position is LSB first on the wire, so the caller reverses the position field (as TI's driver does).\n\nPINS: one RS-485 transceiver per encoder: CLOCK out on one R30 bit, DATA driven through the transceiver driver from DATA_TX (R30) with its driver enable on DATA_EN (R30, DE = 1 only during the lead-in and the mode command), and the receiver output on DATA_RX (R31). TI's EnDat receiver uses the same split (pins endat_out, endat_out_en, endat_in). A PRU pad is either an input or an output, so TX, EN and RX must be different pad indices.\n\nSTAGED SCOPE (NOT implemented): other mode commands (parameters, memory area selection, reset, test values), additional data 1/2 and the EnDat 2.2 command supplement (MRS code), telegrams longer than 32 bits (needs a second accumulator register), propagation-delay compensation for clock rates above 2 MHz (requires IEP timestamping).\n\nPeripheral resources (selection rule): the hard EnDat peripheral (PRU-ICSSG three-channel peripheral interface) is preferred when available and correctly pinned; fallback is bit-banged PRU via an RS-485 transceiver - the staged PRU initiator consumes zero dedicated peripheral instances (no UART/SPI/IEP required in fallback). All four pins must sit on the same PRU-ICSSG slice through pinmux (AM64x/AM243x/AM261x). Isolation: the owning PRU slice must be the only master driving CLK_PIN, DATA_TX_PIN and DATA_EN_PIN during a telegram. Concurrent workload: the transfer is a busy-wait delay-loop sequence; the PRU cannot service other blocks mid-telegram (budget documented in noOfCycles). Deterministic timing: every clock half-period is a calibrated delay loop (halfPeriodCycles); at 200 MHz PRU, halfPeriodCycles=25 gives ~1.9 MHz, and trecCycles=1000 gives 10 us of recovery. BOM/part: one RS-485 transceiver with driver enable per encoder channel (e.g. SN65HVD / THVD class), termination per the EnDat cable spec. Simulator validation: the real clpru ELF of a one-block design runs on TI pru-simulator in a closed loop against pru-simulator's pru_io/endat_encoder.py through pru_io/rs485_transceiver.py (tests/test_endat_framing.py); EnDat is not yet selectable in the gmake sim front door (ported:false).

RES holds the raw telegram (MSB = start bit); the position is LSB first on the wire, so the caller reverses the position field (as TI's driver does).\n\nPINS: one RS-485 transceiver per encoder: CLOCK out on one R30 bit, DATA driven through the transceiver driver from DATA_TX (R30) with its driver enable on DATA_EN (R30, DE = 1 only during the lead-in and the mode command), and the receiver output on DATA_RX (R31). TI's EnDat receiver uses the same split (pins endat_out, endat_out_en, endat_in). A PRU pad is either an input or an output, so TX, EN and RX must be different pad indices.\n\nSTAGED SCOPE (NOT implemented): other mode commands (parameters, memory area selection, reset, test values), additional data 1/2 and the EnDat 2.2 command supplement (MRS code), telegrams longer than 32 bits (needs a second accumulator register), propagation-delay compensation for clock rates above 2 MHz (requires IEP timestamping).\n\nPeripheral resources (selection rule): the hard EnDat peripheral (PRU-ICSSG three-channel peripheral interface) is preferred when available and correctly pinned; fallback is bit-banged PRU via an RS-485 transceiver - the staged PRU initiator consumes zero dedicated peripheral instances (no UART/SPI/IEP required in fallback). All four pins must sit on the same PRU-ICSSG slice through pinmux (AM64x/AM243x/AM261x). Isolation: the owning PRU slice must be the only master driving CLK_PIN, DATA_TX_PIN and DATA_EN_PIN during a telegram. Concurrent workload: the transfer is a busy-wait delay-loop sequence; the PRU cannot service other blocks mid-telegram (budget documented in noOfCycles). Deterministic timing: every clock half-period is a calibrated delay loop (halfPeriodCycles); at 200 MHz PRU, halfPeriodCycles=25 gives ~1.9 MHz, and trecCycles=1000 gives 10 us of recovery. BOM/part: one RS-485 transceiver with driver enable per encoder channel (e.g. SN65HVD / THVD class), termination per the EnDat cable spec. Simulator validation: the real clpru ELF of a one-block design runs on TI pru-simulator in a closed loop against TI pru-simulator's EnDat encoder model through its RS-485 transceiver model (models not in every pru-simulator revision; tests/test_endat_framing.py); EnDat is not yet selectable in the gmake sim front door (ported:false).

It also sent 10-bit 8N1 characters, while IEC 61131-9 uses start, 8 data bits LSB first, even parity and stop. The macro now builds each character in a full register (start 0, data, even parity, stop 1), pushes it as two FIFO bytes and starts it with its own GO, once per payload byte (txBytes 1..8, the two 32-bit inputs). The CHn_CFG0 write sets the TX and RX frame sizes to 11 bits. Peripheral mode is selected before the global reinit so the reinit flushes the FIFO bytes pushed by the earlier R30 writes, and R31 commands are written as byte fields because a read-modify-write of R31 re-sends status bits as GO/reinit commands (channel 2 never transmitted with a two-byte FIFO).

it wrote the 10-bit receive frame size into the transmit field (CHn_CFG0 bits 15:11) instead of bits 27:16; it read the data byte from R30, which is the output register; it tried to clear the valid flag by toggling the receive enable in R30 instead of writing a one to the flag in R31; and it ignored the parity bit. The receiver now runs at 8x oversampling and is re-armed for every character. For each of the 11 bits of a character it waits for the channel's valid flag, reads the middle sample from the channel's R31 byte, clears the flag by writing its R31 bit, and shifts the bit in. The start, stop and parity bits are checked and reported in a new status output (bit 0 parity error, bit 1 framing error); the data bytes are returned in output1 with the first byte most significant. rxBytes is limited to 0..4, the width of that output, and the RX clock divider is passed as a new macro argument. Simulator tests drive the channel with an IO-Link device model for both cores and all channels, including wrong parity and stop bits, and a SysConfig-generated design is checked to call the macro with matching arguments and to assemble. --- .../iolink_master_block.syscfg.js | 174 ++++++++++-------- tests/test_iolink_sim.py | 136 +++++++++++++- 2 files changed, 229 insertions(+), 81 deletions(-) diff --git a/.metadata/sysconfig/.meta/pru_blocks/application_specific/iolink_master_block.syscfg.js b/.metadata/sysconfig/.meta/pru_blocks/application_specific/iolink_master_block.syscfg.js index 699fbc6..18f01f8 100644 --- a/.metadata/sysconfig/.meta/pru_blocks/application_specific/iolink_master_block.syscfg.js +++ b/.metadata/sysconfig/.meta/pru_blocks/application_specific/iolink_master_block.syscfg.js @@ -109,6 +109,13 @@ function baudToClockDiv(baud) { return div; } +// RX clock divider for 8x oversampling: the receiver takes one FIFO sample per eighth of a bit. +function baudToRxClockDiv(baud) { + var div = Math.round(192000000 / (baud * 8)) - 1; + if (div < 0 || div > 65535) { return -1; } + return div; +} + var iolinkModule = { displayName: "IO-Link Master", defaultInstanceName: "IOLINK_MSTR_", @@ -122,7 +129,7 @@ var iolinkModule = { " 1.
