How to do simulation with PCB land pattern influence in ADS?

I used Murata chip capactors & inductors library for circuits simulation in ADS.
But Murata's document said this library doesn't include land pattern data.
Is there any ready-made pad model in ADS so that I can use Murata library with
lad pattern influence in the simulation ? Or could someone advise how should I do
in another way ? Thanks.

Can someone help with this?Thanks.

You can:

Approximate pad with shunt capacitor or use short transmission line. See if this does affect the performance. If not you don't need to model pads

Measure your part on a substrate with the pads as part of the measurement, and de-embed measuremnt to PAD. TRL or LRM calibration.

Buy Modelithics substrate and pad scalable CLR library. I have the CLR library and it is excellent.
