In order to achieve effective diagnosis strategy, support the fault diagnosis design for PHM (Prognostics & Health Management), a design method of diagnosis strategy based on simulation is presented with a case of certain avionics system. A complete diagnosis strategy can be formed by combing the results of testability simulation and EDA (Electronic Design Automation) simulation, applying the...
In order to achieve effective fault injection and support the fault diagnosis verification for PHM (Prognostics & Health Management), a method for importance analysis of failure mode based on EDA simulation is introduced. In this paper, the influence factors of failure mode importance (Effect Severity Ranking (ESR); Occurrence Probability Ranking (OPR); Detection Difficulty Ranking (DDR)) are...
The circuit fault injection based on EDA simulation is one of the efficient methods of testability analysis. In order to implement fault simulation, the first step is to establish the models that reflect the function or fault modes appropriately. Considering the various components of number systems in PHM system, although the prevalent software contains parts libraries, the symbols in the libraries...
