Reading PSpice Data Files

B

Bob Penoyer

Guest
I'd like to isolate data from a PSpice data file. For example, I'd
like to isolate the gate-source voltage and drain current from a
MOSFET and fit a curve to the data so that I can do some analytical
manipulation on the result.

What is the best way to read the data? Is there a relatively simple
way to isolate pieces of the data as I've described?

Plot the trace you want in probe. Click the trace name so it is
selected (red). The do copy. Paste into notepad and you will have a
list of X-Y values. Select more than one trace with shift-click and
then copy and paste and you will get X Y1 Y2...

I have used mathcad in the paste to read in the data saved in notepad
(save as file.prn). See Mathcad readprn function although on newer
mathcad there are other options.

You can also paste into Excel in the same way.

Thanks to you both. The answer is deceptively/pleasantly simple.

Indeed. The first time I tried it I was astonished how easily it
worked.
