Feature Description

This seems to be a notable oversight in this pass.

There are a few questions on hypotheticals though:

  • should we include scan-chain flops which can be wired into enable flops? sky130 has these, but it also has flops with normal enables too.
  • could this integrate with clockgate if a PDK does not provide an enable flop but provides a clock-gating primitive?
