This paper presents a metric for the efficient application of selective hardening using software-based techniques against soft errors. It offers a method for selecting the resources to be protected obtaining maximum fault coverage with the minimum overhead. Common approaches are based on exhaustive exploration of the solution space or time-consumin...

This paper presents a fault injection system for performing fault injection campaigns on Commercial-off-the-shelf (COTS) microprocessors. The proposed system takes advantage of the debug facilities of modern microprocessors along with standard GNU Debugger (GDB) for executing and debugging benchmarks. The developed experiments on real boards, as we...

Reliability evaluation of Commercial off-the-shelf (COTS) processors against faults induced by radiation is a challenging problem. Some alternatives have been proposed to radiation test but they are very time consuming and lack of the observability needed. This work analyses the possibility to use an HDL model for estimating applications dependabil...

Statistical fault injection is widely used to estimate the reliability of mission-critical microprocessor-based systems when exposed to radiation and to evaluate the performance of fault mitigation strategies. However, further research is needed to gain a better understanding of the accuracy of the results and the feasibility of their application u...
