Hi, newbie here trying to run OpenLane flow on caravel_user_project. My user_project simply assigns all Logic Analyzer outputs as inversions of corresponding inputs. My laptop freezes at the Detailed Routing step, and getting this output:

[INFO]: Running Detailed Routing (log: ../home/smr/uniccass_example/openlane/user_proj_example/runs/24_09_22_21_46/logs/routing/25-detailed.log)...

and

not sure how to proceed

@Sameer Srivastava I think the

child killed: kill signal

is often caused by an out of memory error. Watch you memory while running to be sure.

You can reduce memory usage by using fewer threads

@Mitch Bailey thanks. It worked on a better machine.
