I was using Cadence Spectre for simulations till now, but would like to verify some of my results by simulating the same designs using ADS. I have access to the TSMC90nm pdk and a folder called /models/ads where there are all the models in a ADS understandable format.

But in cadence there is a pdk library which contains parameterised elements (MOS, res, cap etc etc.) that I can drag and drop into the schematic in my library for design/simulations, I am not sure how to set up invoke a similar library in ADS. Could someone help me out with this?

Thanks!
