Due to voltage and structure shrinking, the influence of radiation on a circuit's operation increases, resulting in future hardware designs exhibiting much higher rates of soft errors. Software developers have to cope with these effects to ensure functional safety. However, software-based hardware fault tolerance is a holistic property that is tricky to achieve in practice, potentially impaired by...
Since the first identification of physical causes for soft errors in memory circuits, fault injection (FI) has grown into a standard methodology to assess the fault resilience of computer systems. A variety of FI techniques trying to mimic these physical causes has been developed to measure and compare program susceptibility to soft errors. In this paper, we analyze the process of evaluating programs,...
Many years of research on dependable, fault-tolerant software systems yielded a myriad of tool implementations for vulnerability analysis and experimental validation of resilience measures. Trace recording and fault injection are among the core functionalities these tools provide for hardware debuggers or system simulators, partially including some means to automate larger experiment campaigns. We...
