模拟电路网络撕裂法的子网络划分方案优选

A Sub-network Optimal Decision Method in Network Decomposition Approach of Analog Circuit

摘要:

针对模拟电路网络撕裂方法,研究子网络划分问题,总结了子网络划分时应遵循的基本原则,在此基础上提出了“最大化诊断效率,最小化测试消耗”的子网络划分思想,并从置换激励源,元件、测试点、故障特征灵敏度四方面对子网络划分方案的选择做进一步量化分析,提出了优选标准和具体实施步骤,通过仿真实验,验证了方法的可行性和有效性。

Abstract:

The problem of sub-network optimal decision in sub-networks tearing diagnosis method is studied. The basic principles of selecting the tearing networks when building the sub-networks are summarized. A strategy based on the thought of “maximize efficiency, minimize consumption” is proposed. the standard and implementation procedures is given based on further quantitative analysis of four areas replacement:excitation source, components, test point, fault feature sensitivity. The feasibility and effectiveness of the method is verified by simulation and the results.
