Systematic Capability SC which is a measure of design quality. Who should buy it? Search all products by. It defines functional safety as: MISRA has also developed guidelines for the use of model based development. BS EN applies to any software that forms a part of safety devices or is used to develop a safety related system. Before the launch 611508-3 ISOthe development of software for safety related automotive systems was predominantly covered by the Motor Industry Software Reliability Association guidelines.

Those requirements are listed in a document called the certification scheme.

What is IEC 61508?

Requirement for SC are presented in a series of tables in Part 2 and Part 3. A set of guidelines for the development of vehicle based software was published in November iex The standard requires that hazard and risk assessment be carried out for bespoke systems: IEC specifies techniques that should be used for each phase of the life-cycle.


Each device in the design has an SC rating. The safety integrity level SIL provides a target to attain for each safety function. To obtain the MCDC modified condition decision coverage coverage information, one will need a Unit Testing tool, sometimes referred to as a Software Module Testing tool. Software written in accordance with IEC may need to be unit testeddepending up on the SIL level it needs to achieve.
