Test Analysis of Complex Electronic Equipment Based on Multisignal Model
The equipment testability is a design characteristic to determine the equipment’s active status accurately and isolate its internal breakdown.Regarding complex electronic equipment,it is difficult to realize the deep level failure isolation because of the multidimensional structure,the signal interlocks,and the complexity of internal causal relation.The multisignal model uses a system causal relationship of a multilayer direction graph,to build system failure dissemination characteristic establishment model.Using the multisignal model to descript complex electron equipment,the causes and effects dependence,the TEAMS model can carry on the test appraisal in the defective space and improve electronic system fault isolation rate and the coverage fraction.As the multisignal model’s modeling method is simple,the diagnosis speed is quick,and it can improve system’s test,it may apply in complicated system’s test design,the fault mode influence,the failure diagnosis and the test appraisal,and so on,meets the modern complex electron system’s failure diagnosis need.
