Design Summary:
Number of errors: 0
Number of warnings: 2
Slice Logic Utilization:
Number of Slice Registers: 244 out of 126,800 1%
Number used as Flip Flops: 214
Number used as Latches: 28

Number used exclusively as route-thrus: 7
Number with same-slice register load: 6
Number with same-slice carry load: 1
Number with other load: 0
Slice Logic Distribution:
Number of occupied Slices: 163 out of 15,850 1%
Number of LUT Flip Flop pairs used: 467
Number with an unused Flip Flop: 238 out of 467 50%
Number with an unused LUT: 103 out of 467 22%
Number of fully used LUT-FF pairs: 126 out of 467 26%
Number of unique control sets: 16
Number of slice register sites lost
to control set restrictions: 22 out of 126,800 1%
A LUT Flip Flop pair for this architecture represents one LUT paired with
one Flip Flop within a slice. A control set is a unique combination of
clock, reset, set, and enable signals for a registered element.
The Slice Logic Distribution report is not meaningful if the design is
over-mapped for a non-slice resource or if Placement fails.
OVERMAPPING of BRAM resources should be ignored if the design is
over-mapped for a non-BRAM resource or if placement fails.
