Abstract

The study mainly includes three modules: circuit automatic simulation, dependency matrix conversion and fault simulation. Firstly, through the netlist file and the command file of rail transit sensor, we integrate the fault modeling and fault injection of the circuit by Saber software. According to the FMEA analysis table and the research requirements, the study proposes a fault simulation technology which firstly convert the results of the FMEA analysis into a fault sourcetest dependency matrix, then setting up the simulation analysis that needs to be performed and the feature response that needs to be extracted. In the end, design and implementation of automated FMEA Software has been established and it can realize the function of fault simulation and fault diagnosis of the system.
