if this mosfet is in subckt form.

I tried .probe I(*) but it didn't work!
You just don't see mosfet terminal current no matter how.

By the awy, I am using AvanWaves to plot waveforms.

thanks a lot

Try .probe i1(m1) for drain curent, i2(m1) for gate current and so on.

If your mosfet is inside an instance, you will have to give the correct path for it.
For example: .probe I(XI0/m1*), where XI0 is the instance.

I am trying to do something similar in cadence using Hspice as the simulator. In my case the mosfet itself is defined as a subcircuit i.e instead of having a mosfet defined as MPM1 in netlist it is defined as XPM1. Then how can the device pin currents be measured?

The error seen is:
Element xpm1 in print, plot, probe or measure statements is invalid. Output is ignored.

The same thing when done with spectre as the simulator works fine and plots the device pin currents. In its netlist the devices are not defined as XPM instead simply as PM.
The model file description for both contain the device definition as subckt..
