It is pretty cool. 😃

clock_cycles = 1 if L == 0 else 2**L + 1

I don't totally understand why 2^L+1 is the right number of cycles, but choosing something that is somehow related to the number of latches seems perfectly reasonable, I suppose.

input_rows = []
for _ in range(clock_cycles):
input_rows.append("".join(rng.choice("01") for _ in range(I)))

stim_path = aag_path.with_suffix(".stim")

stim_path.write_text("\n".join([*input_rows, "."]) + "\n")

FWIW, this might be slightly more readable/maintainable as a loop. Something like this:

with open(stim_path, 'w') as f:
    for row in input_rows:
        print(row, file=f)
    print('.', file=f)

print(f"wrote {stim_path}")


def main() -> None:
for aag_path in sorted(INPUT_DIR.glob("*.aag")):
write_stimulus(aag_path)

print(f"wrote AIGER stimulus inputs to {INPUT_DIR}")


if __name__ == "__main__":
main()
