What you'll learn:
- Functional Safety
- ISO 26262
- ISO 26262-5: Product development at the hardware level
- Hardware Fault Classification
- Single Point Fault Metric
- Latent Fault Metric
- Hardware Safety Requirements
- Hardware Design
- Probabilistic Metric for random Hardware Failures
- Hardware Safety for Electric Vehicles according to ISO 26262
This course is about ISO26262-4: Product development at the system level. All relevant clauses of this part of ISO26262 are explained in the course. The following clauses are considered:
Clause 6: Specification of hardware safety requirements
Clause 7:Hardware design
Clause 8: Evaluation of hardware architectural metrics
Clause 9: Evaluation of the safety goal violations due to random hardware failures
Clause 10: Hardware integration and testing
The following aspects are considered in Clause 6: Specification of hardware safety requirements:
The ISO26262 V-model for the hardware phase
Refinement of the Hardware Software Interface (HSI)
Characteristics and attributes for the hardware safety requirements
The following aspects are considered in Clause 7:Hardware design:
Relevant aspects for creation of the hardware design
The 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 categories
Decision Tree for fault classification according to ISO26262
Calculation 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 failures
Calculation 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 cases
Test methods
The 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 ISO26262:2018 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 ISO26262 the first part of the course is optional and you can skip it.
