摘要
文中根据系统模块间故障影响度和故障传播关系,基于模糊有向图,实现了系统级BIT设计的系统划分。划分时,不仅充分考虑了系统可测性设计要求和系统级BIT设计特点,还对故障概率、多故障模式、故障影响的传递性进行了分析和计算。实验结果表明,文中提出的方法优于其它方法。
According to the influence and propagation of the faults between modules in a system, a method for system partition in the design for system - level built-in test (BIT) is proposed by the directional fuzzy graph. Not only the feature of the design for testability(DFT) and the design for system- level BIT is considered, but the faults probability, multi -fault, the transition of the faults influence is analyzed. It is experimented to be better than the present methods.
