@User Is there anything special that needs to be done to set up ngspice and xschem? I followed the newer video for the open_pdk/xschem installation and then the older video for the ngspice install. However, in my example folder with the newly copied xschemrc file, it doesn't seem I can generate any netlists or simulate from the test_nmos. Is there something I am missing? These are the two videos I followed: Any suggestions would be greatly appreciated!
