While not able to import S-parameter files directly, PyBERT is now capable of importing exported impulse responses from QUCS. And, with a simple schematic, QUCS is able to extract the differential S[2,1] from a Touchstone file, All of this is available, as of "v1.4".
Issue Description
Currently, the only interconnect model supported is Dr. Howard Johnson's 24 gauge twisted pair model. It would be nice to offer more options to the user. It would be particularly nice to offer an S-parameter import option, so that users could simulate their own custom interconnects.
Suggested Approach
Have a look at the _calcgamma() function in the _pybertutil.py file. This function is where Dr. Johnson's model is "hard-wired" into PyBERT. Therefore, this is the "control entry" point for adding new options.
