To complex electronic equipment,testability analysis is advantageous to improve test effect of equipment.During TEAMS testability,multi-signal model is built by a causal relationship of the system using a multilayer direction graph and used to describe TEAMS result of complex electronic equipment in fault spaces.TEAMS testability can build complex electronic equipment’s fault diagnosis model in highly efifcient and lfexible way,and also can improve electronic system fault isolation rate.In practice,TEAMS can be used to design complex electronic equipment’s testability,analysis fault model inlfuence,diagnose fault and evaluate testability,adapt to the needs of fault diagnosis in complex electronic systems.
