Using Momentum substrate file in schematic simulation (ADS 2012)

Hi all,

I am using ADS 2012 in my circuit designs. However, for the PDK I am using, there is no transmission line libraries created already with this PDK. So, it is not quite convenient in schematic simulation as one needs to do EM simulation for each transmission line and uses the results in schematic simulation.

However, there is a substrate definition file for Momentum. I would like to ask that, is it possible to use the substrate definition file of Momentum in schematic simulation ? I am not sure if there is a component in any palette that (W element, MSUB, ... ?) can load this substrate file and use it in schematic window with microstrip line or any Tline component. Could you please suggest ?

Thanks a lot :)
