| Abstract: |
| The using of Programmable Logic Devices (PLD) in new type fuzes makes software safety becoming a fatal factor influencing whole system′ s safety. The software failures may cause hardware action abnormally through interface between software and hardware, and the abnormal action may cause mishap. Software safety analysis is an effective way to assure software safety. Software Failure Modes and Effects Analysis technique was applied to analyze fuze software safety, including lifecycle risks that may caused by software from ammunition handling to disposal. The key steps of analysis as well as the general software failure modes and the exact causes were given. A case study on analyzing a double micro-controllers based fuze system found an unacceptable risk which isn′ t being controlled, which proved the effectiveness of SFEMA technique. |
