Hi all, after running the

make pre-check

step, I’m getting the following error in 10th step (Klayout BEOL):

Any ideas?

Is this the same as https://skywater-pdk.slack.com/archives/C017HPHCMEY/p1635219667041800 or https://skywater-pdk.slack.com/archives/C01E06TUSC9/p1635626730031700 ? Check your

precheck_results/<datetime>/logs/klayout_beol_check.log

 file? Does it look like it finished successfully? It may be an

out of memory

error. I've heard of designs taking up to 60GB.

@User Thanks a lot for the reply. There is nothing like

finished successfully

in the log file. But it says that the memory usages suddenly jumped to around 6.5GB and my total memory is 8GB. So it seems that this is a memory issue.
