Behavioral models of digital devices based on Radial Basis Functions (RBF) are incorporated into a Finite-Difference Time-Domain (FDTD) solver for full-wave analysis of in-terconnected drivers and receivers. This modeling strategy allows a very accurate and efficient full-wave solution of interconnection structures with possibly complex geometry including the nonlinear and dynamic effects of real-world digital devices, without the need of detailed transistor-level models. Examples of signal integrity and field coupling analysis are shown.
