摘要

Method for simulation of an electrical circuit by synthesis of a physical model, using digital wave structures including the following steps: within the framework of digital wave structure, consider a serial and parallel adapter block with at least three ports of which one adapted; represent said electrical circuit connecting the elements together by means of a plurality of said adapter blocks; connect each adapter block to the adapted port of the previous adapter block; consider the plurality of said adapter blocks as nodes of a binary tree and said elements of said electrical circuit as leaves of said binary tree; apply an element of the aforesaid electrical circuit to the adapted port of the root node; consider, for each port, an incident wave and a reflected wave; starting from the lower leaves of the tree and moving towards the root, calculate each reflected wave; assess the reflected wave of the element connected to the adapted port of the root; starting from the root and moving towards the lower leaves of the tree, calculate each incident wave; update the status of any dynamic elements present in the leaves.
