Merge pull request #3264 from jix/invalid_ff_dcinit_merge 
opt_merge: Add `-keepdc` option required for formal verification
 2022-04-02 12:41:28 +02:00
Jannis Harder ca5b910296 opt_merge: Add `-keepdc` option required for formal verification 
The `-keepdc` option prevents merging flipflops with dont-care bits in
their initial value, as, in general, this is not a valid transform for
formal verification.

The keepdc option of `opt` is passed along to `opt_merge` now.
