I am trying to setup a monte-carlo simulation given a spef file. In this spef file, is modeled equations which can be solved based on the command line parameters which i want to specify as inputs to monte-carlo as opposed to the analog components like voltage, Resistance and so on like explained in the ADE Examples. Could someone help me out here with this?

I have the design routed in cadence and have the spef file. I want to run RC extraction on this spef file using the monte carlo simulation with triggers which I would like to setup in ADE or any other recommended tool which is compatible
