I am not sure why this number oscillates so much- yesterday baseline was -46993 and today it was somehow regoldened to -320 and my code makes it back to -47000. This is also the test that gets affected by my change- with correct para now, it fallsback to the PRIMA dcalc path and - without my isExternal fix, it would have crashed in PRIMA. So this testcase is really stress testing my change

It seems like the -320 value comes from PR one month ago. In any case I would expect your change to degrade (i.e. fix the reporting on) designs with hierarchy enabled, which swerv_wrapper seems to be one of.

weird. yesterday I saw it -46993 in my local run.

"finish__timing__setup__ws": -239.109,
"finish__timing__setup__tns": -46693.1,

I wonder if this is exposing an issue in PRIMA delay calc now.. witherways, orthogonal..
