Description

This course is about ISO 26262-4: Product development at the system level. All relevant clauses of this part of ISO 26262 are explained in the course. The following clauses are considered:Clause 6: Specification of hardware safety requirementsClause 7: Hardware designClause 8: Evaluation of hardware architectural metricsClause 9: Evaluation of the safety goal violations due to random hardware failuresClause 10: Hardware integration and testingThe following aspects are considered in Clause 6: Specification of hardware safety requirements:The ISO 26262 V-model for the hardware phaseRefinement of the Hardware Software Interface (HSI)Characteristics and attributes for the hardware safety requirementsThe following aspects are considered in Clause 7: Hardware design:Relevant aspects for creation of the hardware designThe following aspects are considered in Clause 8: Evaluation of hardware architectural metrics:Hardware fault classification (Safe Fault, Single Point Fault, Residual Fault, Dual Point Fault, Multiple Point Faults, Latent Fault)Examples for several hardware fault categoriesDecision Tree for fault classification according to ISO 26262Calculation of the Single Point Fault Metric (SPFM) and the Latent Fault Metric (LFM)The following aspects are considered in Clause 9: Evaluation of the safety goal violations due to random hardware failures:Evaluation of the safety goal violations due to random hardware failuresCalculation of the Probabilistic Metric of random Hardware Failures (PMHF)The following aspects are considered in Clause 10: Hardware integration and testing:Methods to derive test casesTest methodsThe course includes an exercise for determination of the hardware metrics SPFM, LFM and PMHF.A possible solution for the exercise is presented in a video.In the first part of the course you get a quick overview of all ISO 26262:2018 parts. Also the term functional safety is explained in the first part of the course. And you get an overview of functional safety standards for other industries, such as nuclear plants or process industry.In case you already have some basic knowledge about functional safety and ISO 26262 the first part of the course is optional and you can skip it.
