Miodrag Milanovic 131b557727 Initial implementation of synthesizable assertions 2023-02-13 17:23:26 +01:00
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.

Iris Johnson ccc6060f52 Makefile: properly conditionalize features requiring compression. 2022-04-07 20:07:44 -05:00
whitequark b43c282e4e Add WASI platform support. 
This includes the following significant changes:
  * Patching ezsat and minisat to disable resource limiting code
    on WASM/WASI, since the POSIX functions they use are unavailable.
  * Adding a new definition, YOSYS_DISABLE_SPAWN, present if platform
    does not support spawning subprocesses (i.e. Emscripten or WASI).
    This definition hides the definition of `run_command()`.
  * Adding a new Makefile flag, DISABLE_SPAWN, present in the same
    condition. This flag disables all passes that require spawning
    subprocesses for their function.
