Hi Raja, I suppose below documents help to you for PSpice. http://w2.cadence.com/appnotes/TransmissionLineApplicationsInPSpice.pdf http://www.spicemodel.com/technotes/transmissionlines.pdf You can easily simulate to coupling effect of AC or DC power lines on transmission line in Allegro SigXP or Hyperlynx or another tools.

The First trace is a power trace which is 28V AC and Max Current on the trace is 2 A, and the proximity trace seperated by "S" mils is the signal trace which I am interested in. Inorder to measure the near and far end crosstalk on the signal trace in the frequency domian, How should I model the source and load in PSpice?
