#2061 Segmentation violation (SIGSEGV) at Global Routing Resizer Timing Optimizations (gfmpw-1c) Issue created by algofoogle Description Hi there! This may be exactly the same as #2035 and already fixed (but awaiting deployment?). In any case I'm including this bug report in case it helps provide another test case. I'm using caravel_user_project tag

gfmpw-1c

to harden a user project macro, and I have frequently had it crash on step 20 (Global Routing Resizer Timing Optimizations). This seems to be unpredictable, but can be worked around for any given iteration of my design if I fiddle marginally with things like

FP_CORE_UTIL

. Reported error:

PDK Version Verification Status: MISMATCH
The version of open_pdks used in building the PDK does not match the version OpenLane was tested on (installed: e0f692f46654d6c7c99fc70a0c94a080dab53571, tested: dd7771c384ed36b91a25e9f8b314355fc26561be)
This may introduce some issues. You may want to re-install the PDK by invoking `make pdk`.
