Using Model-based Development for ISO26262 aligned HSI Definition


The ISO 26262 safety standard for road vehicles, among other engineer standards, was established to provide guidance for the development of safety-critical systems. Providing evidence of consistent, correct, and complete system specification covering different work-products is crucial in this context. One of these required work-products is the hardware-software interface (HSI) definition. The HSI definition is especially important since it defines the interfaces between different engineering domains (such as system development, HW development, and SW development). Model-based development (MBD) is the most promising approach to support consistent description of the system under development in a structured way. This paper thus presents an ISO 26262 aligned hardware-software interface definition tool approach which bidirectionally combines the versatility and in-tuitiveness of spreadsheet tools (such as Excel) and the properties of MDB tools (e.g. different views, levels of abstraction, central source of information, and information reuse). The approach presented is capable of defining an ISO 26262 compliant HSI and enables automatic derivation of basic software configurations according to these interface definitions. Index Terms—model-based development, ISO 26262, hardware-software interface.
