Abstract

An efficient algorithm is presented here for simulating large, passive, microstrip layouts using a circle of influence approach with a full‐wave/integral‐equation‐based numerical solver. The procedure involves dividing the circuit into standard subcomponents or blocks and assigning a circle of influence for each block. Reiving on physical intuition, the computation of the couplings between blocks is then limited to those that fall within the circle. By adjusting the circle size, different orders of parasitic coupling can be included in the simulation process. Local junction effects from the individual blocks and the parasitic couplings between blocks that are in close physical proximity can always be taken into account. Aided by a newly developed graphical user interface, the tradeoff between computational efficiency and accuracy is examined by varying the diameter of the circle of influence. Data are presented to illustrate the effectiveness of this new approach. © 1992 John Wiley & Sons, Inc.
