The software complexity in modern vehicle electronic systems is increasingly growing. Vehicle projects have to take into account a growing number of interconnected functions, which are jointly developed by many persons in many different companies. For facing these challenges, new design methodologies for a formalized and partially automated software development are required. The DaVinci design methodology has been developed to match the specific requirements of distributed automotive systems. This includes the function-oriented design of the system structure as well as the deployment on a network and software integration on ECUs (electronic control units). Such a design serves as basis for an automatic code generation process, which integrates the applications into an efficient ECU target architecture with real-time operating system (RTOS) and communication stack. Typical scenarios during the development processes like the reuse, exchange and integration of design data are supported and combined with a flexible configuration management. PC-based test environments may be used for functional integration tests or verification of the network communication. This article is supposed to give a brief overview of the methodology as well as some selected aspects of its implementation in the DaVinci tool suite.
