I've had OrCAD 16.6 up and running for a few days. I'm interested in the PSpice 64 bit probe data. (I believe this does not require a 64 bit operating system).
Are the internal calculations done 64 bit too?
My question is silly!
There would be no point in internal calculations being done 32 bit, only to present the result in 64 bit!
64 bit calculation is applicable only for waveform display. This ensures higher precision of data. You may want to refer PSpice What's new, 16.6 section for additional details on this.
