With FPGA becoming increasingly popular for use in the field of aerospace, the importance of FPGA software reliability and safety to safety critical systems is particularly prominent. However, research on FPGA software reliability and safety is quite insufficient. Concerning this issue, it is necessary to carry out research on FPGA software reliability and safety. In this paper, a reliability and safety metric model based on FPGA software lifecycle is created and safety evaluation network based on BP neural network theory is established. Moreover, a reliability and safety evaluation tool is developed with MATLAB GUI. Comparing with traditional weight evaluation method based on Analytic Hierarchy Process (AHP), the neural network evaluation method has better accuracy, adaptability and practicability.
