    Does anyone know PSpice Model Editor well?

    The background to the question, when you are creating a new model (MOSFET) from a data sheet, Model Editor (ME) has a window with the LEVEL 3 parameters at the bottom, and a window in the top right with several tabs with curves; Transconductance, Transfer Curve, Rds(on), Rev. Drain Current etc.. When producing curves, there are always 1 or 2 of 3 parameters that are swept, while one is held constant. For example, with a transfer curve, VDD is held constant, Vgs is swept, and Id is measured, and Vgs vs. Id is plotted.

    My question is this: ME does not allow you to enter a value for the fixed parameter, VDD in my example above. If it does have a field somewhere, I have not been able to find it. The same goes for all the other tabs I mentioned above, there is no where to enter the fixed value. So while trying to match the curves with actual data sheet curves or actual bench-swept curves, how can I do it if I don't know what I am matching to?
