3. COMDES-II Framework COMDES-II: Component-based Design of Software for Distributed Embedded Systems [version 2] A domain-specific software framework providing modelling concepts and constraints for different issues in the problem space of a distributed real-time embedded system, such as: Component structures, interaction, hierarchy System architecture, concurrency Environmental physicality (external events, etc.) Time

COMDES-II Toolset Eclipse + CodeWorker Java API Verification models COMDES-II Meta-models xme files Component/ Application models Component Implementations (C files, makefile) Model checkers (e.g. UPPAAL) Automatic synthesis Model transformation Input Parsed repository compiled Code generator GME Application configurations, linker scripts Configurator read Executables for deployment stored

9. Conclusion Provides an overview of the generative programming approach for COMDES-II Various modeling concepts and models of computation in COMDES-II are presented Meta-models and semantic constraints of COMDES-II components established in GME are discussed and exemplified An automatic code generation technique developed with CodeWorker tool is demonstrated The deployment of executables based on GCC is briefly described
