Hi
I've been trying to implement an infineon power switch model (SPA12N50C3_L1) in virtuoso. I used the NMOS4 from the analoglib for the purpose and I added a model file that i got from infineons website. I also added the command line 'simulator lang=spice ' at the beginning of the code. However it still keeps throwing up errors. I came across another cadence thread where someone had said that this command line would only convert Berkeley spice and not pspice code. I am attaching the unedited code bit below
simulator lang=spice
