Enhancing the Robustness of System on FPGA by Routing Isolation

Due to their high performance and flexibility, FPGAs have become an attractive solution for space applications. However, SRAM-based FPGAs are particularly sensitive to radiation-induced Single Event Effects that may lead to configuration memory corruption. We propose a methodology for enhancing the reliability of redundant design implemented on FPGAs. Statically analyzing the implementation of the circuit to identify and reduce the single points of failure of redundant systems, we can increase the system's robustness by controlling the placement phase.
