Dear Efabless administrators, I'm working on the AI_by_AI project and I had my previous solved issue in this conversation (https://web.open-source-silicon.dev/t/16134922/caravel-user-project-make-openlane-failed#47997459-1b4e-465b-910a-817ec3303748). I now continue with the project and meet another problem with the "make user_project_wrapper" command. This problem is exactly raised in step 19 "Running Global Routing". Has anyone run this project successfully? I'm glad to receive your instruction! Thank you for your consideration!

is often an out of memory error. Can you watch the memory as you run?

I think it is same in my system too... but it is not using much memory

I'm running this hardening process with a Virtual Machine having 32GB memory, 1 core, and 6 logical processes. The memory use sometimes increases to more than 30GB.
