Crash during Global Routing Resizer Timing Optimizations #1543

Closed mole99 closed 1 year ago

mole99 commented 1 year ago

Description

I am currently trying to reharden a design for submission to GFMPW-0. While this previously worked well, now I get a crash during Global Routing Resizer Timing Optimizations. The design can be found under https://github.com/mole99/caravel_wfg_gf180/tree/ol-issue in the branch ol-issue. Edit: The issue appeared after I updated my design to tag gfmpw-0d of caravel_user_project.

Expected Behavior

To successfully finish the flow.

This test case is not properly packaged:
