About this event

A live 30-minute expert session on Structural Coverage — Statement, Branch, and MC/DC Explained with Worked Code (V-Model — The V-Model & Safety Lifecycle). What We'll Cover: Where structural coverage measurement sits in the unit-test rung of the V and what it does and does not prove Computing coverage step by step: instrumenting code, reading MC/DC truth tables, and analyzing uncovered code How coverage targets map to IEC 61508-3, ISO 26262-6, and DO-178C objectives and the coverage reports produced Common mistakes: chasing 100% with meaningless tests, unjustified deactivated code, and coverage measured on the wrong build The coverage-gap justifications and dead-code dispositions auditors expect alongside the raw percentages Related topics: structural coverage · mcdc coverage · branch coverage · statement coverage · code instrumentation · coverage analysis · dead code · deactivated code · coverage justification · unit testing · do-178c coverage · coverage tools · truth tables · coverage gaps Critical Systems Analysis provides embedded functional safety consulting for V-Model — The V-Model & Safety Lifecycle.

About Functional Safety Foundations

This online session delivers expert-led instruction on the regulatory landscape and implementation approach for Functional Safety Foundations.

The cross-sector fundamentals underlying every functional safety standard: risk as severity × likelihood, the safety function concept, integrity levels, the safety lifecycle, and the split between random and systematic failures.

What it regulates

Shared vocabulary and reasoning: hazard → risk → risk reduction allocation → safety requirement → verified implementation → maintained integrity in operation.

Who must comply

Everyone entering the field — the conceptual base of the entire catalog.

Key requirements of Functional Safety Foundations

  • Hazard and risk fundamentals
  • Safety function anatomy: sensor-logic-actuator with defined safe state
  • Integrity ladders (SIL/PL/ASIL/DAL) as risk-reduction currencies
  • Random vs systematic failure treatment
  • Lifecycle and management of functional safety incl. competence

Key concepts: Functional Safety Foundations

Functional safety management
Planning, competence, documentation and assessment wrapped around technical work.
Random vs systematic
Hardware wear-out/chance failures quantified statistically versus design/process errors controlled by rigor.
Risk reduction allocation
Distributing required risk reduction among mechanical design, safeguards, control functions and procedures.
Safe state
The defined condition a function drives the equipment to on demand or fault.

Frequently asked questions: Functional Safety Foundations

Why can't testing alone prove safety?

Rare-event targets (like 1e-7/h) are unverifiable by test duration, and systematic errors evade random testing — hence the standards' dual machinery of quantified hardware analysis plus process rigor and independent assessment.
