SOFIA: An automated framework for early soft error assessment, identification, and mitigation

The occurrence of radiation-induced soft errors in electronic computing systems can either affect non-essential system functionalities or violate safety–critical conditions, which might incur life-threatening situations. To reach high safety standard levels, reliability engineers must be able to explore and identify efficient mitigation solutions reduce the at initial design cycle. This paper presents SOFIA, a framework that integrates: (i) set fault injection techniques enable bespoke inspections, (ii) machine learning methods correlate error results architecture parameters, (iii) techniques, including: full partial triple modular redundancy (TMR) as well register allocation technique (RAT), allocates critical code (e.g., application’s function, layer) pool specific processor registers. proposed novel variations RAT are validated through more than 1739k injections considering real Linux kernel, benchmarks from different domains multi-core Arm processor.
