SEU fault-injection at system level: Method, tools and preliminary results

An approach to study the effects of single event upsets (SEU) by fault injection performed at system-level is presented. It is illustrated by results obtained on two different versions of a matrix multiplication algorithm, one standard and the second with fault tolerance capabilities. The final goal of this work is to validate fault tolerance techniques implemented at software level and provide a feedback about the weakest variables, improving thus their capabilities to tolerate faults.
