Abstract
The UML (Unified Modeling Language), with the enhancements in UML 2.0, is receiving interest by an increasing number of industrial and academic groups from the EDA, embedded software and hardware systems, who look at it and at its extension mechanisms as a practical and standard means to define family of languages targeted to specific application domains and levels of abstraction, while providing unification. In the Embedded Systems and SoC (System-on-Chip) area, we defined a model-driven design methodology based on UML 2.0, UML profiles and C/C++/SystemC. In this paper, we extend this design flow in order to support the platform-based design principles. We also present the architecture of a prototype tool, which provides a graphical representation in UML (from a highlevel functional model down to RTL) of hardware and software components, C/C++/SystemC code generation from UML models, and a reverse engineering process from C/C++/SystemC code to UML models.
