Thank you for your response. Unfortunately it does not answer my question. Let me try to be more specific:
I already know how to open results, view and plot voltages and currents in ocean and analog artist.
I want to plot the small signal parameters of the BSIM4 model of some transistors during a transient sim. Particularly, I want to track how the gm, cgd, and cgs change as a function of time. These are transistor parameters, not voltages and currents.
How do I:
1) save these in simulation
2) plot them as a function of time.
And just to be completely clear, I am NOT interested in the operating point of these devices at a single time step like you can access using the menu: Results -> Print -> Transient Operating Points OR the calculator expression: OPT("/dut2/MNP" "gm") which only give me these parameters at a SINGLE point in time, not as a waveform in time.
This is a trivial thing to do in HSPICE, so I assume it must be a trivial thing to do in Spectre and Analog Artist. I just can't find it.
