Hello Experts, I am wondering if any of you out there is using S-parameters in the Cadence Spectre environment. I am using two ports in a .s32p file in a simple sp analysis to confirm that the Spectre generated insertion loss and return loss match the HFSS plot of the same. I am there qualitatively but the numbers don't match. I have tried to play around with the order for the rational fitting process but to no avail. My next stop is Cadence support but thought I would check in with the community to see if anybody had the "secret sauce" figured out. Thanks for your help.
