A straight foreword identification of a suited implementation of distributed embedded systems is increasingly restricted by the complexity of the solution space and the size of such systems. The proposed specification method denoted as hierarchical CoDesign Model is based on a hierarchical approach, which easily supports the reuse of components and allows a dynamic adoption of the level of detail of specifications. Therefore, the complexity of a specification can be adjusted to the current requirements of the designer. Input/Output Relations provide a powerful means to capture system behavior on different levels of abstraction. The resulting advantages of these concepts are demonstrated by the means of an MP3 decoder application example.
