@Ruige Lee In wrapper are you placing any standard cells? Can you share your repo with configuration file?
r
I have uploaded the repo. Although I have modified the design files, which is different from the 
issue_reproducivle
. But it will meet the same crash. https://github.com/whutddk/Rift2Fake_gf180_mpw0

sorry，I may upload a wrong branch
@Vijayan Krishnan I have pushed the new branch gf180mcu

Thank you, but how can I use that patch in 
caravel_user_project
? Just modify the tag of openlane to 
2022.12.01
?
v
@Ruige Lee have you raised github issue for this in OpenLane?
r
no，but I updated the tag, and the crash did not happen again
v
Ok. Goto OpenLane installed directory and update 
dependencies/tool_metadata.yml
into openroad_app commits to latest 
522aab058ebdc053a066289e98abac5a47ae811e
and run 
BUILD_IF_CANT_PULL=1 make openlane
and run the flow again
