Hello everyone! I am currently going through the quickstart guide for the Caravel user project. After running the hardening command (make user_proj_example) I end up get error messages after Step 17

[ERROR]: during executing openroad script /openlane/scripts/openroad/droute.tcl

I also get the following lines. Any solution?

[ERROR]: Flow failed.

Is this being ran on a memory-constrained system? It could be possible that your system is running out of memory, and killing the openroad process. If you're on linux, what does

dmesg -T | grep 'killed'

say?

Running on Windows/WSL my laptop has 8 GB of ram, but I check task manager and the ram usage is at roughly 80%.

It's still worth checking for OOM (Out Of Memory) killer action IMO, because the WSL VM may have had a limited amount of RAM (auto-)assigned to it

Increase your swap memory and try once

Ended up doing the quickstart guide for Caravel on my desktop computer which has more RAM. Hardening of the user_proj_example went without issues and I did not get stuck at step 17.

Nice! Have fun designing!
