Power report does not consider clock-gating cells high activity #5

Closed kanndil closed 2 years ago

The latches of the clock gates should have 1.0 activity factor.

The power reports are updated considering the clock-gate cells' latches activity. Check benchmarks

Use OpenSTA commands to get the clock gated flipflops and assign 0.1 activity factor to them. Instead of calculating an estimate based on the number of clock gated cells.
