We measure real world structures, but we simulate ideal structures. The first step in an accurate simulation is starting with an accurate model of both the drivers and receivers and the interconnect elements. With accurate material properties, uniform transmission line structures can be accurately modeled. Discontinuity structures such as DC blocking capacitors, connectors and vias can be modeled using a 3D full wave solver with outputs in the form of S-parameters. From either measured or simulated S-parameters of a structure, simple figures of merit such as the excess capacitance and inductance or a transmission line model can be fit by hacking the S-parameters. Examples of some of these valuable techniques to model interconnects for integration into circuit simulations will be shown.
