Risk, Reliability & Functional Safety Knowledge Base

Computer-Aided Specification and Design Tools — IEC 61508

Computer-aided tools help engineers create clear, consistent safety requirements and designs. Learn how they support IEC 61508 compliance and reduce systematic failures early in the lifecycle.

Structured Diagrammatic Methods in Functional Safety

Structured diagrammatic methods provide visual, rigorous ways to specify and verify safety requirements. Learn how they support IEC 61508 compliance and reduce systematic failures.

Use of Trusted and Verified Software Elements — IEC 61508

Trusted and verified software elements are pre-qualified components used to reduce development effort and systematic risk. Learn how IEC 61508 defines their use in safety applications.

Graceful Degradation — Degraded Mode in Safety Systems

Graceful degradation defines how a safety system behaves when full redundancy is lost. Learn how to specify, quantify, and verify degraded-mode behaviour to maintain functional safety.

Diverse Monitor Techniques in Functional Safety

Diverse monitor techniques use independent monitoring channels to detect failures that a primary channel may miss. Learn how IEC 61508 applies them to control systematic and random failures.

Failure Assertion Programming — IEC 61508 Software Technique

Failure assertion programming inserts checks into safety software to detect and respond to unexpected states. Learn how IEC 61508 uses it to prevent systematic software failures.

Error Detecting Codes in Functional Safety — IEC 61508

Error detecting codes identify corrupted data in safety-critical communication and storage. Learn how IEC 61508 recommends them and how they contribute to systematic failure control.

Fault Detection in Functional Safety — IEC 61508

Fault detection identifies hardware and software failures before they cause unsafe conditions. Learn how IEC 61508 defines fault detection coverage and why it matters for SIL achievement.

Backward Traceability in Functional Safety Requirements

Backward traceability ensures every implemented element can be traced back to a safety requirement. Learn how it supports IEC 61508 verification and prevents gaps in safety coverage.

Forward Traceability in Functional Safety Requirements

Forward traceability ensures every safety requirement is implemented and verified. Learn how IEC 61508 uses it to demonstrate complete coverage across the safety lifecycle.
