Summary
set_disable_clock_gating_check/unset_disable_clock_gating_checkaccepting Liberty cells, instances, ports, and pins.set_disable_inferred_clock_gatingas a compatibility alias.write_sdc.disable_clock_gating_checkregression.Motivation
Inferred clock-gating check disables previously only covered instances/pins and were not named consistently with SDC-style
set_disable_clock_gating_check. Cell-level disable is needed when all instances of a clock-gating cell should skip the check.Notes
