With Current, you can evaluate the charge mathematically.

As known from basic textbooks, if you integrate instantaneous current over time, you get the total charge.

For a very simplistic case, just start with a current source across a capacitor with a transient simulation. Set the initial condition to V(C)=0V, and have the current source switch from 0 to a constant current at a time after the simulation starts, say, at time t0=1s. For the case of constant current, the charge delivered to the capacitor equals Q=i*(t-t0). In case of non-constant current, the product i*(t-t0) needs to be replaced by the integral i(t)dt from t0 to t.

I know how to calculate and plot it in Micro-Cap circuit simulator. In Transient Analysis Limits Window enter next:

- in "X Expression": type v(C1)

- in "Y Expression": type Q(C1)

Maybe similar functions are present in software you mentioned.

You need to sense the current through the capacitor and integrate this current with time. Or you need to read the voltage across the capacitor and multiply it by C. So you can your the operators in your simulator to get Q. Naturally the second method is simpler since you need only a multiplication process.
