Hi all,

Can anyone suggest me a method through which i can avoid the lengthy procedure of 'extract_rc' everytime that i do an insert_buffer/verify_zrt_route or whatever. I have utilized the multi-cpu options but still it uses up a lot of my time. I know in encounter we have an option.

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
editDeleteViolations
globalDetailRoute

yeah even i found a similiar way..
just use the set_eco_timing (similiar command) to false and it will not extract RC again.
