Jannis Harder c0063288d6 Add the $anyinit cell and the formalff pass 
These can be used to protect undefined flip-flop initialization values
from optimizations that are not sound for formal verification and can
help mapping all solver-provided values in witness traces for flows that
use different backends simultaneously.

Zachary Snow a650d9079f verilog: fix width/sign detection for functions 2022-05-30 16:45:39 -04:00
Jannis Harder 4bfaaea0d5 verilog: fix size and signedness of array querying functions 
genrtlil.cc and simplify.cc had inconsistent and slightly broken
handling of signedness for array querying functions. These functions are
defined to return a signed result. Simplify always produced an unsigned
and genrtlil always a signed 32-bit result ignoring the context.

Includes tests for the the relvant edge cases for context dependent
conversions.

nosync prevents latches from being needlessly generated.
