Towards satisfaction checking of power contracts in Uppaal

Since energy consumption is one of the most limiting factors for embedded and integrated systems, today's microelectronic design demands urgently for power-aware methodologies for early specification, design-space exploration and verification of the designs' power properties. To this end, we currently develop a contract- and component-based design concept for power properties, called Power Contracts, to provide a formal link between the bottom-up power characterization of low-level system components and the top-down specification of the systems' high-level power intent. In this paper, we present a first proof of concept for the verification of the leaf-component power contracts of a hierarchical system design w. r. t. their implementation in UPPAAL. Building on these, we can provide assured power contracts for the hierarchical Virtual Integration (VI) of the leaf-components to a compound power contract of the integrated final system and thus allow for a sound and traceable bottom-up integration and verification methodology for power properties.
