Have imported a simple flex ribbon cable Allegro layout into SiPro which worked fine. Setup all of the ports and finished the simulation which completed and converged without any warnings or errors.
Went to the S-Parameters plotter under "Results", then went to the "Mixed Mode" tab and started selecting individual lines to pair together making differential pairs. Once that was done, I noticed I could get Return Loss plots, but could no longer get Plot Through Path plots on the differential pair as I did with the indiviual lines.
Am I missing something or is that something that is incorrect thinking with respect to differential line pairs?
