Abstract:To solve the problem that it is difficult to model the system-level fault injection experiment efficiently,this paper presents a novel method for fault model construction,which constructs the dynamic fault tree using the language level data flow graph.Through analyzing the data flow of fault process,the data dependence relations are found out,and a generation algorithm of the fault model is proposed.Compared with other algorithms,the algorithm presented in this paper processes the dynamic characteristic.Moreover,it can increase the fault coverage,reduce the system cost and make it easier to implement the fault injection experiment.
Keywords:data flow graph  fault model  fault injection  fault coverage
