Hi ,
I have this spice code from ALADIN website, it is supposed to be the spice file for two nmos transistors connected in a certain way in one chip as in the attached figure.
I want to create this new component in Virtuoso to uses in the schematic.
I searched a lot around and I found CDF editing tutorial but it does not work since the parameters does not show up in the CDF form. Could any one help me in this.
Thank you
