During this phase the necessary activities and processes needed to develop safety critical hardware are planned.
These activities and processes include:
- Hardware implementation of the technical safety concept
- Analysis of potentioal hardware faults and their effects
- Coordination with software development
5-5 Initiation of Product Development at Hardware Level
- Planning of safety activities in hardware development - Further refinement of the Safety Plan
5-6 Specification of Hardware Safety Requirements
- Derivation of hardware safety requirements from the technical safety concept and system design specification - Specification of reliability requirements to be met by hardware - Detailing of the hardware-Software Interface specification
- Design the hardware in accordance with the system design specification and the hardware safety requirements - Verify the hardware design against the system design specification and the hardware safety requirements
5-8 Evaluation of the Hardware Architectural Metrics
- Evaluate the hardware architecture regarding the compliance to the safety requirements - Single Point Fault Metrics (SPFM) - Latent Fault Metric (LFM)
5-9 Evaluation of the Safety Goal Violations
- Prove that the risk of a safety goal violation, dus to random hardware failures, is sufficiently low (Use PMHF or Joe Miller method)
5-10 Hardware Integration and Testing
- Verification of the compliance of the developed hardware with the hardware safety requirements and hardware specification, by testing.
