Functional safety standard's techniques and measures in light of electromagnetic interference

Abstract

Everyday modern electronic programmable systems are performing more and more safety-critical tasks. Due to electromagnetic interference (EMI), these systems potentially violate their predefined safety goals. Appropriate actions must be taken to ensure the system's integrity. This paper looks at proposed safety standard techniques in the light of EMI. Redundancy and error detection and correction schemes are not only reviewed, but recommendations are provided to increase the EMI-resiliency of the considered system.
