Simulate Variable Capacitor

I am new to Cadence and I would like to sweep a Capacitor value in my design from 1fF to 10fF but I do not know how to do so. I am using ADE L, may you please give me some suggestions of how to go about doing this.

You should first set the capacitance parameter of you capacitor (in schematic) to a variable name e.g ”CAP”. An example of analogLib/CAP is shown below:

Then in ADE-L menu, select Variables-> Copy From Cellview to get CAP variable displayed in 'Design Variables' section in ADE.

After that, you can sweep the variable CAP with different values using the Parametric Analysis Tool in ADE (Tools->Parametric Analysis.. in ADE-L menu). To find how to add the sweeps look at the below manual:

Virtuoso Analog Design Environment L User Guide -- Analysis Tools - Using the Parametric Analysis Tool

Thank you
