Hi, I run stages from synthesis to routing. After that, I run

run_parasitics_sta

, from my understanding this performs SPEF extraction and do STA. But when I looked at the resulting log file under signoff, the delay between cells is still zero. Should not this be a non-zero delay now since RC extraction is done so there must be a non-zero delay now on the nets? Below is the log file

parasitics_multi_corner_sta.log:

Its good to open issue here: https://github.com/The-OpenROAD-Project/OpenLane/issues with test case and commands you used with this log to debug further

Also try to increase the digits to view your result using the -digit switch, there should be slight difference

Thanks! Increasing the digits solved the problem
