Different number of hold violations reported by sta::endpoint_violation_count and report_timing_paths

[alexroach-rl]

Hello All,

When I try to report the number of hold violations using "sta::endpoint_violation_count min", I get around 50 reported. However, when I try to display the violating paths using "report_timing_paths -path_delay min -slack_max 0", only 2 paths are reported. I am guessing that 50 is the true number and the report_timing_paths command is only reporting a subset of the violating paths. If so, is there any way to report all of the violating paths? I am running these commands in the TCL console after running "make gui_final", if that makes a difference.

Can you provide a test case?

I'll see what I can do regarding a test case. Thanks for your reply!

I did a bit more playing with the report_checks command. Could the report_checks command be only reporting a single path to each endpoint by default, whereas the endpoint_violation_count function returns the number of all violating paths to each endpoint?

That sounds quite likely as report_checks has:

-endpoint_path_count The number of paths to report for each endpoint. The default is 1.

Try setting it to a large value and see though it may be very slow.
