Selection Method of Minimum Test Set at Circuit Board Based on Improved Node Matrix
Graph theory is applied in this paper to optimization design of test point set in circuit board fault diagnosis. The optimal detection node set of a circuit board can be established by a improved node matrix. The improved node matrix can also regenerate topology network graph of a circuit, which reflects the relationship among every node and the working status of all components in the circuit.
