26 Sphinx Model Editors ITEA 2-26 of 36

27 Variants Model and Editors Problem: Handling the complexity and the variety of products, especially when combining hardware and software components. Solution: Combined modeling of variants (hardware and software) and their dependencies (properties, constraints). Tool: Prototype for variant handling. ITEA 2-27 of 36

28 Component Model Problem: Software construction includes the use of heterogeneous behavioral models or hand written code that have to be integrated in order to be processed. Solution: Provide an open and extendable component model that integrates different behavioral models (used as input to the tool chain and code generators). Example: Component Model of pedestrian traffic light crossing. ITEA 2-28 of 36
