摘　　要：故障样本选取是测试性验证中的关键环节,直接影响测试性验证试验的效率和结果的正确性。在板级电路的故障样本选取过程中,运用传染病思想中的元胞自动机模型分析了电路故障的传播行为,提出了一种基于元胞自动机的故障样本选取方法,实现了故障样本的等效选取。以某型装备关键部件为例,建立了故障传播模型,计算并改进了元胞自动机状态计算方法,通过注入易操作的故障样本,简化了故障注入的流程,提高了故障注入效率。Sample selection is the key link in fault verification test,it has a direct impact on theaccuracy of the efficiency and results.In fault sample selection process of board-level circuit,thecellular automaton model in infectious is used,thought to analyze the behavior of circuit faultpropagation,fault sample selection method based on cellular automata is proposed,toselect the faultsamples equivalent is achieved.In a certain type of key equipment components,for example,a faultpropagation model to calculate and improved cellular automata state calculation method is established,streamlined processes by injecting fault samples which easy to operate,improve the efficiency of fault injection.
