Experiences with AUTOSAR compliant Autocode generation using TargetLink

Increased safety, comfort and emission norms are pushing the complexity of vehicle systems up exponentially. Model-based development processes have increasingly been adopted for the development of automotive embedded control software to help implement the complex systems and reduce the development time. Model-based and autocode technology has become mature and brings many advantages in automotive software development. In parallel, consortium of major OEMs and suppliers are driving towards standard specification of automotive software architecture, AUTOSAR (AUTomotive Open System Architecture). AUTOSAR would enable flexibility for product modification, upgrade and update scalability of solutions within and across product lines. To model algorithms and generate AUTOSAR compatible Autocode has become the necessity for the projects using AUTOSAR architecture. To streamline development phases and shorten them effectively, seamless integration between the architecture system design models and algorithm models, ECU testing and calibration is required. This paper focuses on the coupling between architecture system design models and algorithm models and to Autocoding.
