Title: SPICE/Keysight ADS Netlist Help
Post by: fourierpwn on August 06, 2016, 12:55:30 am

Hi guys, I am trying to import a nonlinear model for a HEMT device into Keysight ADS (beginner with ADS) and I don't understand the netlist format that ADS gives. I have been through Keysight tutorials to which they provide sample netlist files of a diode to import, which I understand. The nets in that are logical and I can see where everything should connect together. However, the HEMT model netlist format seems bizarre.

Here is a screen capture of the model imported into ADS.

I am aware that you can simply import the model as a netlist and use that in your design, or create a subcircuit to use, however I would like to know how all of the parasitics are connected so that I can reproduce the model myself (for use in other EDA packages).

Ignoring the netlist names and looking at the component names, I understand about Cgs, Cds, Cgd, Ls, Lg, Ld though I don't understand what the others are for, i.e., Cgs1, Cds1, Lg1 etc.

Any ideas?
