Hi All: I am facing issues with the s-parameter file generated from spectra-quest for interconnects for one diff pair to be used for PCIe Gen2 simulation in HSPICE. I am getting the entire signal reflected back from the point where s-parameter starts. I am using spectra-quest to extract the routed nets in sigxp then generate the s-parameter from sigxp. Then using that s-parameter in HSPICE net list to do the simulation. Has any one come across same or similar issues? OR know of the correct procedure to do this? Thanks in advance.
