The replacement of the former, purely mechanical, functionality with mechatronics-basedsolutions, the introduction of new propulsion technologies, and the connection of cars to theirenvironment are just a few reasons for the continuously increasing electrical and/or electronicsystem (E/E system) complexity in modern passenger cars. Smart methodologies and techniqueshave been introduced in system development to cope with these new challenges. A topic that isoften neglected is the definition of the interface between the hardware and software subsystems.However, during the development of safety-critical E/E systems, according to the automotivefunctional safety standard ISO 26262, an unambiguous definition of the hardware-softwareinterface (HSI) has become vital. This paper presents a domain-specific modelling approach formechatronic systems with an integrated hardware-software interface definition feature. Thenewly developed model-based domain-specific language is tailored to the needs of mechatronicsystem engineers and supports the system’s architectural design including the interfacedefinition, with a special focus on safety-criticality.
