A hybrid technique for system-level signal integrity and EMC assessment

This paper presents a hybrid technique for the system-level assessment of signal integrity and electromagnetic compatibility of digital electronic systems. We describe a stable procedure for the inclusion of behavioral models of digital drivers and receivers into a finite-difference time-domain mesh. The behavioral models for the devices are based on radial basis function (RBF) formulations, allowing for inclusion of intrinsic nonlinear and dynamic effects. The particular adopted formulation allows us to apply the hybrid method to investigate both interference from incident fields and radiation for interconnected structures loaded by realistic drivers and receivers.
