I'm using klayout inside the OpenLane docker image...
# klayoutm

03/21/2023, 3:49 PMI'm using klayout inside the OpenLane docker image (make mount) and looking for suggestions on the best way to utilize the sky130 lyp, lyt, DRC, and LVS files in /openlane/pdks/sky130A/libs.tech/klayout. I can import and set these up each time I call klayout, but I'd like something persistent. However, klayout wants to create /.klayout which is not writable in the docker.
Is there a way to specify the .klayout directory for klayout other than the $HOME directory?
