Cadence ''I-V Law'' Definition

[Knyquist]

Hello!

I would like to define a stimulus in Cadence Eldo that imposes on a certain pin the Waveforms of both the Voltage and the Current for the transient analysis.
Is it possible? Maybe using a stimulus file\script?

Of course if I were to use a Voltage generator to define the Voltage law I wouldn't be able to impose the Current law and viceversa.

Thanks and Best Regards.

If you want to define both voltage and current from one
end, then you have to have some authority over what's
going on at the other - you can't vary I, V independently
into a fixed resistance load.

Ok, that's fairly right.

But this does apply only if the specified I-V component shares completely its port with the resistance.
What I would like to do is to simply specify that from a certain pin in the circuit, the voltage will follow a certain waveform and the current drained from it will follow another specified waveform as well.


Thank you anyway for your reply!
