Pspice and Orcad errors and solving them?

[treez]

Hello,
Do you know the best guide to learning orcad/pspice simulations. I am getting "undefined subcircuit" error, as well as "errors during netlisting", and obviously not converging.

Not sure if this will solve your problem, but I have fixed errors of convergence by using models for non-ideal components, including the simplest, like resistors, capacitors, etc...
