A Convergent Iteration Scheme for Semiconductor/Circuit Coupled Problems

Abstract

A dynamic iteration scheme is proposed for a coupled system of electric circuit and distributed semiconductor (pn-diode) model equations. The device is modelled by the drift-diffusion (DD) equations and the circuit by MNA-equations. The dynamic iteration scheme is investigated on the basis of discrete models and coupling via sources and compact models. The analytic divergence and analytic convergence results are verified numerically.
