Set model params Automatically

[StreAMnewal]

There is width (w) param in my PMOS schematic.
How can I automatically set some params in PMOS in schematic using
equation like this:
Source diffusion area = w*x
Source diffusiion periphery = (w+x)*2

Does the iPar function do what you want? For example:

Source diffusion area = iPar("w")*x
Source diffusiion periphery = (iPar("w")+x)*2

Where can I set this function to all MOS examples from some library?
w is width. How can i paste width in Ipar function?

You would need to do this in the CDF for the component. Use Tools->CDF->Edit
CDF, and pick the component you want, and put the expression in the right field.

You might want to read the Component Description Format documentation.

Or you might want to look at the PDKs Design Topic on the Cadence Support site:

Follow the link to PDK Development and Testing, and the resulting search hits
are useful to give you more background.
