Hi All I have touchstone s-parameter (.s4p) files of my input connector, via, trace and output connector. Now i want to unite these in HSPICE. I used to do a complete model in HFSS, but since it is a 3d modelling tool, it will take a long time. That's why i have decided to use HSPICE. So can anyone help me out in concatenating these touchstone files to a single touchstone file (.s4p) in HSPICE?
