Toward SIL Evaluation for a Resilience Strategy

It is not rare that a Micro Processor Unit (MPU) receives an electric noise, and caused the function malfunction or freezing. A novelty resilience strategy is proposed in order to reduce the risk of error caused by noise and improve the system safety. Safety Integrity Level (SIL) is the part of the overall safety of a system or piece of equipment. This paper describes a resilience strategy against electronic noise and proposes several consideration toward the SIL evaluation.
