Re: Synopsys : To avoid extract_rc while running insert_buffer/ verify_zrt_route
here is an example:
# dont update timing and placement when eco command applied.
setEcoMode -batchMode true -refinePlace false -updateTiming false
getEcoMode
< do your ECO commands>
# to keep existing routing
refinePlace -preserveRouting true;
# this command could required long time, need to apply all ecoChangeCell previously requested
setEcoMode -batchMode false -updateTiming false;
# clear existing violation & re-route
