Transistor current in Hspice

[rosaeidi]

Hi

I write the following code in Hspice to view the drain curren of M1.

.print I1(M1)

After simulation without error, this current didn't appear in output files. Does anyone know the reason?

What should I do to measure the transistor current?

Add something like .option post

it maybe appear in current 1 of Results Browser, but not in current

put I(M1) instead of I1(M1)... this defaults to drain current

and of course use ".option post "

Added after 4 minutes:

and if u are bothered for all device currents and voltages

simply put

.probe v(*) i(*)

this will post all the voltages and currents in heirarchy

agree.
and make sure the instance name of transistor is same as it in netlist, such as mxn*, mxp*

Thanks alot!
