Switch Matrix System for Automatic Test Path Finding Algorithm

This paper introduces a switch matrix system that uses a configurable switch matrix to realize test channel switching. Through this configurable switch matrix system, N channels to be tested can be connected to N channels to be tested according to user requirements. Since the design of each node of the switch matrix is similar, it is convenient to expand and reduce horizontally and vertically according to the requirements. Switch Matrix adopts a double-layer design, which can obtain the optimal connection path between the tested channel and the tested channel with a path search algorithm.
