Find Critical Path in Cadence Genus?

[Hillts]

I am trying to find the critical paths of the ISCAS benchmark circuits, and am not sure how to do that. Is there a method of doing this in Genus, as well as finding what types and # of gates are in this path?

Thank you in advance !!

report_timing is the command you are looking for

report_timing is the command you are looki

Are the gates listed after running the command the ones in the critical path? Thanks for the reply btw

yes, the default behavior is to print one path, the most critical one

just one limit to this report timing command, it does not check the path is real, means it could impossible to stimulate the path in reality.

yes, but there is no other approach. this is how STA works.

right, long time ago, PT was a "true" argument in the report timing and the tool should report only true path, but this is take too long and the argument rapidly disappeared.
