Study on Design Method of Embedded Diagnosis Strategy Based on Simulation

In order to achieve effective diagnosis strategy and support the fault diagnosis design,a design method of embedded diagnosis strategy based on simulation is presented with a case of certain avionics system.A complete diagnosis strategy is formed by combing the results of testability simulation and EDA (electronic design automation) simulation,applying the dependency matrix theory and signal acquisition & processing theory.The presented method provides an effective approach to apply optimal diagnosis strategy obtained by simulation to practical engineering,which can guide actual embedded diagnosis design and improve the level of diagnosis and testability design.
