Abstract: As a signal transfer hub, switch matrix plays an extremely important role in the automatic test equipment (ATE). When the distance between the source node and destination node is the shortest, signals can be transmitted in a most efficient way. First, a physical model of switch matrix is presented. Then a mathematical model is constructed by using graph theory. In view of the least relay and highest reliability, the problem is considered as a shortest path search in un-weighted graph and weighted graph. These two graphs arestudied by BFS algorithm and Dijkstra algorithm, and the improvedalgorithm is put forward. An actual example shows how to build the model and find the optimum path. The improved algorithm could realize rapid automatic searchfor the optimum path, thus has potential applicationsin development of general adapters and design of software platform in ATE.

Key words： switch matrix path search BFS algorithm Dijkstra algorithm
