Hi all,

I simply want to obtain the DC current value through a particular
inductor. It is not included in the operating point solution. Is
there a way to tell HSPICE to output this value, short of running a
transient simulation and looking at t=0?

Thanks,

Robert

You might want to insert a voltage source with Voltage = 0 in series with
the inductor. A voltage source has no Ri and does not interfere with your
simulation if the voltage is zero.

Observe the current from this source.

Thanks Bjørn, your suggestion works fine. I was hoping I wouldn't
have to do this sort of netlist manipulation, however. I need to
obtain the current through all inductors in an automated fashion (for
a utility I'm creating) for arbitrary circuits.
