Hello. My little problem is that:
I need to use pwm controller ucc2891, so i downloaded a library from http://focus.ti.com/docs/prod/folders/print/ucc2891.html .It contains a full model. But when i try to use it, there is wrote "Wrong device $CDNENCSTART". So i tried look into code and i saw this:

.........
etc....


Any idea what`s wrong and how can I fix it?
Maybe Tina`s version doesnt fit?
Thanks for answer.

 

It's an encrypted subcircuit file.
There's a mention of this type in the PSpice User's Guide; here:

Page 63

I've not encountered encrypted subcircuit files up until now.
