Verilog-like bitslicing for Python.
Install the library from PyPI:
pip install bitslice
Bitslice is designed to behave as an integer value as much as possible.
All operators defined on int should be supported.
Bitslice objects use indexing to emulate Verilog-style bit slicing.
from bitslice import Bitslice
value = Bitslice(5, size=4)
# Binary: 0b0101
print(value)
0x0005 (5)
# Select the lowest bit (index 0, right-most)
#
# index: 3210
# value: 0b0101
print(value[0])
0x0001 (1)
# Select bits 2 -> 1
# resulting in 0b10 == 2
print(value[2:1])
0x0002 (2)
# Set the upper bit
value[3] = 1
# 0b1101
print(value)
0x000D (13)Advanced features: slice aliasing
value = Bitslice(5, size=4)
value.add_alias('lower', start=0, end=1)
value.add_alias('upper', start=2, end=3)
value['lower'] == value[1:0]See bitslice.py for more examples.
