This paper will first introduce and classify the basic principles of architecture-driven software development and will briefly sketch the presumed development process. This background information is then used to explain extensions which enable current behavior modeling and code generation tools to operate as software component generators. The generation of AUTOSAR software components using dSPACE's production code generator TargetLink is described as an example.

Function models have a well-established position in automotive software development. Formal system models, on the other hand, are rare. This article describes the various aspects of function and system models, focusing mainly on AUTOSAR-compatible models. It also depicts the challenges for future overall models that combine the function models and the system model, and the resulting benefits, such as early system verification via PC-based simulations.

Over the last few years the introduction of explicit system and software architecture models (e.g. AUTOSAR models) has led to changes in the automotive development process. The ability to simulate these models on a PC will be decisive for the acceptance of such approaches. This would support the early verification of distributed ECU and software systems and could therefore lead to cost savings. This paper describes an implementation of such an approach which fits into current development processes.
