want to measure current?

Hi all,

I want to measure the current using CCCS . When I am selecting the nodes of the CCCS the spectre simulator stops saying fatal error.

 Error: (CMI-2238) :FO : Inappropriate or missing probe.

How to remove this error.

Any help much appreciated..

Thanks a lot !!!!

    It's a bit of an odd thing to do to use a current controlled current source to measure a current, but regardless of that, the problem would get resolved by not omitting the probe or specifying an appropriate one!

    My guess is that on the properties of the cccs component you have not specified Name of voltage source which needs to be the name of the voltage source through which the CCCS will probe the current, and then generate a current which is a multiple of that (looks as if you have the gain set to 1 though, so it should just mirror the probed current).

    Regards,

    Andrew.
