COMBEST will provide a formal framework for component based design of complex embedded systems. This framework will:

• Enable formal integration of heterogeneous components, such as with different models of communication or execution;
• Provide complete encapsulation of components both for functional and extrafunctional properties and develop foundations and methods ensuring composability of components;
• Enable prediction of emergent key system characteristics such as performance and robustness (timing, safety) from such characterizations of its subcomponents;
• Provide certificates for guarantees of such key system characteristics when deployed on distributed HW-architectures

To achieve these objectives, COMBEST will:

• Develop a design theory for complex embedded systems, fully covering heterogeneity, interface specifications, composability, compositionality, and refinement for functional and extra-functional properties
• Build on substantial highly recognized background results of the academic partners, partly carried out within the integrated project SPEEDS;
• Extend results of the Integrated Project SPEEDS, both regarding heterogeneous rich components and compositional analysis methods.
