In the rapidly evolving technological landscape of the automotive industry, embedded systems are becoming increasingly complex. Designing new systems from scratch requires substantial time and resources, particularly in the safety-critical domain. Fortunately, reusing proven legacy safety mechanisms from previous projects can be an attractive strategy to reduce development time, lower costs, and leverage verified reliability. However, simply … Read more

Hey there, fellow automotive engineers! If you’ve been wrestling with ISO 26262 compliance lately (and who hasn’t?), you’ve probably encountered the somewhat intimidating concepts of Dependent Failure Analysis (DFA) and Safety Measures. Today, I want to break these down into practical, applicable insights that you can actually use in your day-to-day work. The Safety Challenge … Read more

The Hidden Key to ISO 26262 DFA: Everything About Coupling Factors Hello everyone! Today, I’d like to talk about Coupling Factors – a concept frequently mentioned but often difficult to understand deeply in the world of automotive functional safety. Having spent years developing safety systems as an automotive engineer, I’ve experienced firsthand how crucial this … Read more

As system complexity increases in automotive functional safety, the importance of analyzing dependent failures that occur through interactions between multiple elements is growing. The ISO 26262 standard requires Dependent Failure Analysis (DFA) to systematically manage these dependent failures, with Initiator (or DFI, Dependent Failure Initiator) being the core concept that serves as the starting point … Read more

If you’re in the automotive industry, you’ve likely heard of ‘ISO 26262’ and ‘ASIL.’ What was once considered merely ‘regulation for regulation’s sake’ has now become the cornerstone of automotive safety. I’d like to share the real-world challenges and solution strategies I’ve experienced while implementing ASIL in my functional safety work. ASIL Allocation: The Complex … Read more

Balancing Safety and Efficiency: New Challenges in Modern Automotive Systems As modern automotive systems evolve into more integrated and cost-optimized platforms, mixed ASIL (Automotive Safety Integrity Level) environments have become commonplace. It’s no longer unusual for ASIL D safety-critical components to share the same ECU with Quality Management (QM) elements or even legacy software. How … Read more
