Simulation of stray capacitances (Cgs, Cgd,Cds) with double pulse test

I would like to make a sweep of capacities. As I see in the .lib file there are Cgs, Cgd and Cds functions of voltage.

  1. I would like to keep the voltage dependencies and sweep at the same time? If it works can you tell me how?

What I have already tried with 1). I define in SpiceLine2 Cgs = {Cgs} and then I try to perform sweep unfortunately did not work.

  1. I would like to delete the function and sweep without voltage dependency.
    But I do not understand why in .lib file occur several times. Which function should I delete? Assuming I want to sweep Cgs, Cgd and Cds from CAB425M12XM3.

For example Cgs occurs 63 times. In total 29 MOSFETS are executed in .lib file. I expect a number which I can divide by 29.

Thanks!
