A reliable fault classifier for dependable systems on SRAM-based FPGAs

This paper presents an algorithm for the discrimination of faults in FPGAs based on their recovery possibility; some faults can be recovered by reconfiguring the faulty part of the device, others have a destructive effect. After classification has been carried out, the suitable fault recovery strategy is applied, with the final aim of enabling the exploitation of FPGAs, in particular SRAM-based ones, for critical applications, such as the ones in the space environment. In this scenario, we investigate the reliable implementation of the fault classification algorithm, that can be so integrated in an overall reliable system.
