Functional Safety Training


Description

Whenever safety depends on the correctness of certain functionality, be this the flap control in an aircraft, the flame detection in a burner furnace, or the lid interlock of a washing machine, a case of “functional safety” is present. To achieve and demonstrate functional safety is particularly challenging, especially if such functionality is implemented in complex microelectronics and software. Standards have been developed to address these challenges, with IEC 61508 as the “mother standard” on functional safety, from which many domain specific or product specific standards have been derived. (E.g.: IEC 61511 for the process industry, IEC 62061 for machinery, ISO 26262 for on-board automotive systems, IEC 61800-5-2 for safety-related motor drives, EN 50156-1 for furnace control systems, …)

This course provides a common sense understanding of the fundamental aspects and principles of functional safety. It explains how these aspects and principles are implemented by concepts and requirements of IEC 61508 and derivate standards.

It provides an overview on what is required to design and develop a safety-related control system in a way that provides the necessary confidence to rely on the safety-related functionality it provides —and, ultimately, to help fulfill the requirements necessary for certification of products or systems in accordance with IEC 61508 and derivate standards.

Completion of this course enables to efficiently conduct self-study of IEC 61508 and derivate standards.

 

Workshop topics include:

  • It’s all about safety: System Safety, Product Safety, Functional Safety, Software Safety
  • Why is there something called Functional Safety?
  • The world according to IEC 61508:
    • Equipment under control (EUC), E/E/PE systems, subsystems, elements
    • Hazard and risk analysis, identification of safety functions
    • Risk reduction to be provided  by safety functions – target failure measures
    • Safety integrity level (SIL), mode of operation
    • HW random failures and systematic failures
  • Management of Safety, Management of Functional Safety
    • The overall safety lifecycle
    • The E/E/PE system safety lifecycle
    • The Software safety lifecycle
    • Modification
  • The two levels of Safety Requirements Specification
    • System Safety Requirements
    • System Design Requirements
  • Achieving and demonstrating architectural hardware safety integrity
    • Hardware fault tolerance
    • Failure Modes Effects and Diagnostic Analysis (FMEDA), Diagnostic coverage
    • Type A and Type B elements, safe failure fraction
    • On-chip redundancy
  • Quantifying the effect of random hardware failures
    • Failure rates of hardware components
    • Simplified approach: architectural patterns (“MooN”) and formulas
    • Other approaches: Fault trees, reliability block diagrams, Markov modeling
  • Quantification of the effect of common cause failures
