Application of a Genetic Algorithm for Testing SEUs in SRAM-FPGA Systems

Abstract. Testing of FPGAs is gaining more and more interest because of the employment of FPGA devices in many safety-critical application fields. We propose a prototype of a tool for the generation of test pat-terns for application-dependent testing of SEUs in SRAM-FPGAs based on a genetic algorithm. We focus on SEUs affecting logic resources of the FPGA. SEUs in any configuration bit are addressed, making our fault model much more accurate than the classical stuck-at fault model. Re-sults from the application of the tool to some circuits from the ISCAS and ITC benchmarks are reported
