How to perform Load Pull Simulation in ADS?

Ya...I know there is a design guide, but when I open up I'm confused by the way it can be done for the simulation? Could anybody has the step by step guide for me to refer?

your help is much appreciated.

finding the example in ads by yourself

Try to use "loadpull design guide" ( if you have this license) ..
It will set-up all necessary circuit(s) for you..
