(
)
Ensure consistency between system requirements and hardware requirements. Ensure consistency between the system architecture and hardware requirements. [OUTCOME 6] [ISO 26262-5:2018, clause 6.4.9] NOTE 13: Consistency is supported by bidirectional traceability and can be demonstrated by review records. NOTE 14: In case of hardware development only, the system requirements and system architecture refer to a given operating environment (see also note 13). In that case, consistency and bidirectional traceability have to be ensured between stakeholder requirements and hardware requirements. NOTE 15: Safety related requirements shall be compliant with system architectural constraints such as • Fault tolerant time interval [ISO 26262-5:2018, clause 6.4.7] • Fault handling time interval [ISO 26262-5:2018, clause 6.4.7] • Multiple-point fault detection interval [ISO 26262-5:2018, clause 6.4.8]
