Hi, I am trying to get my simulation environment set up with the vanilla mpw_6c code on mac. I was able to harden, run the precheck, and now trying to use the Docker simenv. I have tried exporting PDK variable and have all the other export such as: OPENLANE_ROOT, PDK_ROOT, PDK_PATH, CARAVEL_ROOT, TARGET_PATH, MCW_ROOT, and DESIGNS. I have also ran the Docker container, said it needed Python3.6+, so I installed Python3.8 and still ran into issues. Below are the two errors I get when running outside and inside of the Docker container. Any help would be appreciated!

Try with setting PDK variable as export PDK=sky130A

I did and get the same result. It seems like the Docker container (not my local machine) is complaining about missing the PDK.

@User This may be bug in new MPW-6 caravel_user_project

I am also trying to get simulation working so please do confirm if this needs to be fixed?

Yes, it seems to be a bug for mac users. You need to add the “-e PDK=sky130A” (line 91) to the command in the Makefile as in the picture above

Only for MAC users? isn't this setting the environment for the docker container so it would apply regardless of the host? we are using linux

Right it is probably for all users. Adding that environment variable should not hurt. I was just surprised because I was able to run mpw_5c (a couple weeks ago) on Windows with WSL Ubuntu without issues. That one did not have the PDK variable

@User Yes I also not notice this issue during MPW-5, this is new change in MPW-6 [May be due to two Skywater Library sky130A and sky130B]
