How to add a new component-part in Virtuoso

Sali

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

    This appears to be a PSPICE model (I'm not sure you really should post it here, but I couldn't find the source to reference it). The simplest way ought to be to just create a new view of type "pspice" (so do File->New->CellView and set the type to be "Pspice". Paste the text of the model (you'll need to ensure your cellName matches the subckt name, so you could call the cell 114913 if you don't want to change that part of the text).

    Spectre however does not support the tolerance parameters in a PSPICE model, so you'd need to remove the lot/4/uniform=-.22 dev/uniform=.04 type specifications for each parameter. Then do a File->Extract and it will prompt you to create a symbol if you don't have one (there are five pins called 1 to 5).

    However, it still won't simulate in spectre because it references a diode model called "dps" which is not defined anywhere. I just added:

    .model dps diode

    and it ran, but of course that's completely invented...

    Thank you so much Andrew for your detailed answer.

    For the reference of spice model , this is the link and it shows only when you create an account and log in there.

    I will follow the steps and try it.

    Thanks again.
