[sdiy] PSPICE models for OTA

[charlie lamm]

Now a dumb/newbie type question.

I have never tried to add .mod files, and have just burned up about 2
hours trying to figure this out, unsuccessfully.

"This should be easy right?"

Do you just change the extension from .mod to .inc?  I have successfully
added .inc files, using the instructions on duncanamp's site.

Or, does someone have a link that explains to a relative newcomer to
pspice how to add parts to a library that are .mod files?

Thanks again for all the help....
