People can turn any PMC model on ex-test into an equivalent equation (or a system of equations), and find all consistent fault patterns based on the equation model. We can also find all fault patterns, in which the fault node numbers are less than or equal to t without supposing t-diagnosable. It is not impossible for all graphic models. 关 键 词：PMC MODEL EQUATION MODEL ex-test system-level FAULT diagnosis DIAGNOSTIC algorithm
