OPA2674 spice model problem with PSpice

[houly]

Hi all,
I have a problem to simulate a simple follower stage using OPA2674... I use PSpice (orcad 10.5.0 CIS option).

I make my own library called OPA2674.lib and olb file.
I edit simulation option to add the file in the library list of my project.

Here is the simulation log :

Does anyone have an idea ?

You haven't picked an easy model to use - it is weird! It works on my simulator but I think the problem may be to do with nested subcircuits. Try moving the following line in the model file

.ENDS OPA2674_Model

to the bottom of the file (and add a carriage return as they couldn't be bothered to include one!).

See the notes at the header of the model.

Keith.
