Abstract

A new approach capable to improve the convergence of relaxation iterations is presented. The method is based on the use of generalized coupling patterns containing additional circuit elements. The parameters of such elements can freely be varied to control the convergence of iterations by suppressing local feedback in the decomposed circuit. In the case of time-domain circuit analysis by waveform relaxation method the adaptive strategy was formulated based on the dynamic estimation of input impedances of the parts in the decomposed circuit
