Hello, James, Please download the latest version, s2ibis3. It has many improvements over s2ibis2. You can set DC pins inside the subcircuit file. They must be set to the correct voltages for each corner, of course. Alternatively, you could edit each spice file generated by s2ibis3, then run spice manually, and then run s2ibis3 for the extraction phase.
