I have a Zetex Mosfet I'm trying to run in PSpice. I change the custom component to X and I'm sure I'm using the right symbol in addition the the .lib ZXMN10A07Z.sub directive but its still not working. I thought I read something about people saying I also need an assembly file but I'm not exactly sure what that is about. Does anyone have any idea? I know its just the MOSFET because if I swap the component out for a similar MOSFET included with the software it works fine.

Your title says LTspice but your post says PSpice. With which are you having the problem?
