An overall system design approach from system design to code-generation based on object-oriented modeling for embedded heterogeneous systems

摘要

In this paper we present a new approach for an overall system design. It supports object-oriented system modeling for software components in embedded systems in addition to time-discrete and time-continuous modeling concepts. Our approach provides structural and behavioral modeling with front-end tools and simulation/emulation with back-end tools. The UML meta model is used for storing CASE data to a MOF object repository and XMI (XML Metadata Interchange format) to interchange this data with UML-CASE-tools. The CASE tool chain we present in this paper supports concurrent engineering with versioning and configuration management. It provides adaptors for the tools MATLAB/Simulink/State flow and ARTiSAN Real-Time Studio as well as an im- and exporter for XML. Utilizing the Unified Modeling Language notation for an overall system design cycle, the focus of this paper lies on the subsystem coupling of different modeling domains and on a new code generation approach.
