2.) How do I know what range of L and W, I can use for a certain model? I'm not sure if the range is determined by LMIN, LMAX, WMIN and WMAX?

The link to the model file is given here: https://www.utdallas.edu/~zhoud/EE 7v88/lect 2/mm0355v.l

I've read this version was publicized so there should be no issue. It uses level 49 hspice or level7 pspice bsimv3.1.

Thanks in advance. I know my question might sound stupid but I'm really desperate for help.

I'm trying to use nch.1

Code:
