Functional Safety Standards Comparison in Electronics

This document is a technical report that provides a comparison of software functional safety standards across the Avionics, Automotive, and Medical electronics domains. It outlines the importance of functional safety in reducing the risk of unacceptable hazards to acceptable levels. The report details the various functional safety standards applicable to each domain, including ARP 4754A, ARP 4761, DO 254, DO 178C for Avionics; ISO 26262 and ISO 25119 for Automotive; and IEC 62304 for Medical electronics. Each standard is described in terms of its guidelines for the development and assessment of systems throughout their life cycle, from inception to maintenance. The document further discusses the systematic and random failures in systems, emphasizing the need for safety analysis and verification. It also compares the safety classification methods and development assurance levels used in these standards, highlighting the critical aspects of safety requirements and risk management in the design and verification processes.
