Description
Particle and ionizing radiation can alter and severely disrupt the normal behavior of electronics, and lead to their premature failure. For this reason, computing systems for space applications have to be designed using methodologies to mitigate such issues. Field Programmable Gate Arrays (FPGAs) provided with reconfiguration capabilities can facilitate the implementation of fault-mitigation methodologies, and allow the use of fault-injector IP cores, which play an important role in the validation of fault protection strategies. In this work, we describe the implementation of a particular fault-injector that, given a target orbit, can simulate transient faults induced by particle radiation at a rate consistent with the characteristics of that portion of space. This fault-injector comprises three different models that can be found in literature, and it has been inspired by previous research in the domain. We also suggest how our tool can be used to validate a smart fault-mitigation technique, based on the mathematical framework known as hidden Markov models, exploiting reconfiguration and spare resources on FPGAs.
