Application of Three Physical Fault Injection Techniques to the Experimental Assessment of the MARS Architecture Johan Karlsson

This paper describes and compares three physical fault injection techniques—heavy-ion radiation, pin-level injection, and electromagnetic interference—and their use in the validation of MARS, a fault-tolerant distributed real-time system. The main features of the injection techniques are first summarized, and then the MARS system is described. The distributed testbed setup and the common test scenario implemented to perform a coherent set of experiments by applying the three fault injection techniques are also described. The results are presented and discussed; special emphasis is put on the comparison of the specific impact of each technique.
