Synergy of UML and Simulink

ion and partitioning can be regarded from three dimensions: Software The key for software specification and development is a target group specific presentation of the realised functions and their connections and distribution for all roles involved along the development process. The partitioning represents the mapping between functional specification from a user’s point of view and the functional architecture of the implementation. Methodology Numerous functional requirements in an automotive ECU can not be handled at once. A methodology has to be defined thus these aspects are handled separately in a deeply structured process, e.g. user functions vs. communication, software architecture vs. hardware architecture vs. software distribution on the components. Tool & Notation The realisation of a structured process handling different abstractions along the path requires the use of the most appropriate notation for each abstraction. The UML provides a much broader range of means of description, with advantages especially for the analysis and design phases. In Simulink a clear defined methodology and modelling guidelines are necessary in order to realise the necessary abstractions and topology descriptions. 2.5. Integration in three dimensions The integration of steps of the development process and objects developed requires the integration in these three dimensions.
