Challenges in Revising the Same Work Product Across Different Phases of the Functional Safety (FuSa) Lifecycle
In the automotive functional safety (FuSa) lifecycle, work products evolve across multiple phases, from concept to decommissioning. A single work product—such as the Safety Plan, Safety Requirements, or Safety Case—undergoes multiple revisions to reflect new information, refinements, and compliance needs. However, managing these revisions across different phases presents significant challenges. 1. Traceability and Consistency Across […]
Challenges in Software Verification and Compliance
Introduction In the world of safety-critical systems, software verification and compliance are not just technical requirements—they are mandatory for ensuring the safety, security, and functionality of the system. With regulations such as ISO 26262, DO-178C, and IEC 61508, developers face significant challenges in meeting these standards. Ensuring that software complies with safety and quality standards […]

Platform-level safety mechanisms are critical to mitigate these risks by providing a robust foundation for […]
Why “Check the Checker” Matters in Safety-Critical Systems
Introduction In the world of automotive functional safety, ISO 26262 mandates rigorous safety mechanisms to detect, mitigate, or prevent failures. However, what happens when the safety mechanism itself fails? Can we blindly trust that an error-detecting system will always work? This is where latent safety mechanisms come into play—designed to verify the integrity of primary […]
The Challenge of Lockstep Safety Mechanisms – Analyzing Failures Due to Random Hardware Faults
Introduction In the world of safety-critical systems, ensuring reliability and fault tolerance is crucial. One such safety mechanism used widely is the lockstep mechanism, where two identical processing units run in parallel and compare their outputs. This redundancy helps catch discrepancies that could signal hardware faults, ensuring that the system operates reliably. However, even the […]
Automotive Safety FuSa Architecture Safety Controller
Introduction In modern System-on-Chip (SoC) designs, a Safety Controller serves as an independent island, responsible for managing functional safety mechanisms (SMs) and ensuring fault detection, error reporting, and system recovery. It operates within a separate wrapper, ensuring functional independence from other IPs. However, integrating the Safety Controller with various IP blocks and their Safety Mechanisms […]
