Is it possible to make a simulation with step load cap? For example 1pF, 2pF, 3pF ... 10pF?

 

Yes. Give the cap a value of something like {C1} (including the curly braces), then insert a directive:

.step param C1 1E-12 10E-12 1E-12

That should step it from 1pF to 10pF in 1pF increments.

 

Or maybe instead of 1E-12 you can use 1p. I'm not sure, I can't test it at the moment.

 

Yes, you can use 1p etc in the step directive.

 

Ohh ty... I was declaring cap name without braces and didint know how to make it work
