Iramma,

I verified that I can run this simulation without any issue in Orcad PSpice Version 16.2. What version of Orcad PSpice are you using? This model is encrypted and will not run in versions older than 15.7.

Thanks,

Nikhil,

I used 16.6 version of ORCAD for simulation.

Iramma,

Yes, I am able to replicate this issue in 16.6. This model was developed in 16.2 and encrypted in that version. It looks like there is some issue with PSpice 16.6 where it is not able to recognize the encrypted netlist from 16.2 in this case. I have released the unencrypted library file to the product folder. It should show up in a day or two. Please pick it up from there and use it instead of the encrypted library.

Thanks,

Nikhil,

Thanks for your support.I will use updated file for simulation.
