I am doing some research about transconductors. I am using OrCAD 16.6 Lite version for my simulations. Model that I am using in my simulations is TSMC 0.35um V01C. That model is optimized for HSpice, but I need it for PSpice. I only changed LEVEL from 49 to 7, and it is working, I get results (results are in expected limits), but with warnings:
1) Using BSIM3 version 3.1 or lower
2) AD=0, AS=0, PD=0, PS=0A
After that, I set: AD=AS=W*L, and PD=PS=2*(W+L). I think I got better results with this setup (better accuracy). Still don't know which values to use for NRD,NRS,NRG,NRB, are these values for number of contacts necessary?
Other try was with LEVEL=8, it works without errors, but I think results are not good enough in AC analysis.
My questions is: How to properly convert HSpice to PSpice in order to get most accurate results in OrCAD PSpice? Or what You suggest to do for better accuracy?
I didn't find answer in similar posts.
Thanks beforehand.
