Fault detection method for the subcircuits of a cascade linear circuit

Abstract

The fault detection method for the subcircuits of a cascade linear circuit is discussed. While there is any fault (either "hard" or "soft" and either "single" or "multiple") at one subcircuit of a cascade linear circuit, it can be quickly detected by using the method proposed in this brief. While there are faults simultaneously existing at multiple subcircuits, they can generally be detected by the searching approach proposed in this brief. The aforementioned method is the continuation and development of the unified fault detection dictionary method for linear circuits proposed in [1].

“…With the development of fault analysis technology, the fast fault diagnosis method has become a hot spot on fault analysis and reliability research of hybrid integrated circuits [ [10] , [11] , [12] ]. The fault dictionary detection method can accurately locate the fault of electronic components accurately, but for the multi-level complex hybrid integrated circuits, the actual fault detection process has a large workload [ [13] , [14] , [15] , [16] , [17] ]. Using machine learning fault diagnosis method can realize fault mode recognition quickly, but it needs a lot of fault data for fast learning and training [ [18] , [19] , [20] ].…”
