The hardware-software interface specification defines the hardware and software interaction consistent with the technical safety concept: the hardware devices and resources controlled by software, their operating modes and configuration, the shared and exclusive use of resources, the timing constraints and the diagnostic capabilities of the hardware and their use by software; it is refined during hardware and software development. This sits in clause 6, whose stated aims, per the SGS quotation, are technical safety requirements for the functions, dependencies, constraints and properties of system elements and interfaces and for their safety mechanisms, requirements for safety in production, operation, service and decommissioning, a system architectural design and technical safety concept that meet the safety requirements without conflicting with other requirements, an architecture analysis that prevents faults and yields the safety-related special characteristics, and verification of it all against the ASIL. Requirement text not held.
