Increasing autonomous fault-tolerant FPGA-based systems´ lifetime

In this paper we propose an automated design flow for the implementation of autonomous fault-tolerant systems on SRAM-based FPGA platforms, able to cope with the occurrence of both transient and permanent faults. The goal of the proposed methodology is to increase the system´s lifetime, by designing it able to detect and mitigate the effects of soft errors, as well as of permanent, non-recoverable ones, by exploiting dynamic reconfiguration. The application of the hardening design flow to a real case study is reported, to validate the methodology.
