What problem does it solve?

This Skill solves the critical need for structured, quantifiable Failure Modes Effects and Diagnostic Analysis (FMEDA) required for functional safety certification of safety-critical hardware and software systems. Without a rigorous FMEDA, teams cannot verify compliance with ISO 26262, IEC 61508, and related regulatory standards, leading to rejected safety cases, costly redesigns, or unsafe products reaching market.

Core Features & Use Cases

• Failure Mode Enumeration & Classification: Systematically lists all credible failure modes for digital ICs, analog components, and software units, classifying each as safe, detected dangerous, undetected dangerous, or multi-point latent/detected.
• Safety Metric Computation: Calculates required regulatory metrics including Single-Point Fault Metric (SPFM), Latent Fault Metric (LFM), and Probabilistic Metric for Hardware Failures (PMHF) to verify compliance with ASIL/SIL thresholds.
• Audit-Ready Artifact Generation: Produces machine-readable FMEDA artifacts that meet Independent Verification and Validation (IV&V) audit requirements, and flags critical gaps such as missing failure rate sources, undiagnosed dangerous modes, unanalyzed common-cause failures, and stale analyses after design changes.
• Use Case: For an automotive ASIL-D electronic brake controller, this skill generates the full FMEDA artifact, verifies all metrics meet the 99% SPFM and 90% LFM thresholds, and flags any missing diagnostic coverage for dangerous failure modes before implementation begins.

Quick Start

Use the fmeda-analyzer skill to generate a complete, compliant FMEDA artifact for your ASIL-D brake pressure monitoring system, including all component failure modes, diagnostic coverage calculations, and regulatory metric verification.
