This paper presents a systematic methodology for the synthesis of SPICE compatible circuits for PCB discontinuities modeling. Measured or numerically evaluated S-parameters are used to obtain the frequency dependent matrix characterization of the structure to be analyzed. Frequency responses are then approximated with rational functions suitable for a stable and passive realization. The equivalent circuit network is finally synthesized and incorporated in a commercial circuit solver that allows both frequency and time domain simulations.
