lutstrings 0.1.4

Python package to reorder init strings

Easy LUT Init String manipulation

You only need two things:

1. A pin mapping given by rapidwright.
2. An initstring in hex format like "0x0123456789ABCDEF"

Then by using the following you can obtain the init string found in the bitstream

from lutstrings import lut
bitstream_init_string = lut.fullConversion(pin_mapping, init_string)

The pin mapping can be obtained using rapidwright from a LUT cell with

pin_mapping = cell_lut.getPinMappingsL2P()

Currently works for any number input luts

Testing

A self test can be run by running pytest in the lutstrings/lutstrings directory

PYTHONPATH=. pytest

or by simply running the test file

python3 test_init_string.py
