Software reliability analysis on embedded system based on SFMEA and SFTA model

The paper puts forward a reverse comprehensive analysis model that can improve the reliability of embedded software with SFMEA and SFTA. First, it adopts SFTA to build software fault analysis tree; Second, it makes severity level definition list according to fault mode; Finally it lists the fault analysis results with SFMEA, then summarizes several important links in software designing and proposes relevant improvement measure. The practical applications show that this model can improve the reliability of software and ensure the quality of embedded software.
