We have released several NuSMV models used for the analysis of a digital camera MPSoC. Click on AMBA to see the models! The results of this analysis were published in the following paper:\n\t\t\t\t\t\t

\n\n\t\t\t\t\t\t\n\t\t\t\t\t\t\n\t\t\t\t\t\t\t\tThe Alderis project focuses on the application of Domain Specific Modeling Languages (DSMLs) and meta-modeling to specify a common semantic domain for the analysis of distributed real-time embedded (DRE) systems.\n\t\t\t\t\t\t\n\t\t\t\t\t\t
\n\t\t\t\t\t\t\n\t\t\t\t\t\t\n\t\t\t\t\t\t\n\t\t\t\t\t\t\t\tThe Alderis language has both a visual and textual syntax with formally defined semantics. Alderis models can be verified directly by the open-source Distributed Real-time Embedded Analysis Method (DREAM) tool available for download at http://dre.sourceforge.net.\n\t\t\t\t\t\t\n\t\t\t\t\t\t
\n\t\t\t\t\t\t\n\t\t\t\t\t\t\n\t\t\t\t\t\tMotivation
\n\n\t\t\t\t\t\t\n\t\t\t\t\t\t\nComponent-based development is an emerging paradigm for the design of distributed real-time embedded (DRE) systems with hard QoS support. Components refer to reusable pieces of solutions, which can be configured and composed together to provide a service. Alderis plans to support this paradigm shift by providing a language and semantic domain for the model-driven development (MDD) of DRE systems.\n\t\t\t\t\t\t\n\t\t\t\t\t\t
\n\t\t\t\t\n\t\t\t\t\t\tModel-Driven Development
\n\n\t\t\t\t\t\t\n\t\t\t\t\t\t\nThe Alderis language is specified using meta-modeling as shown in the figure below. We use the GME modeling environment to specify Alderis. The figure shows a part of the Alderis meta-model with its corresponding concrete syntax. The red arrows show how modeling elements and their relations are specified by the meta-model.\n\n\t\t\t\t\t\t

Formal Verification & Analysis
\n\n\t\t\t\t\t\t\n\t\t\t\t\t\t\nA key property of the Alderis language is that it has formally defined semantics allowing real-time verification using timed automata model checker tools such as UPPAAL and the Verimag IF toolset. The DREAM tool provides a way to automatically generate the timed automata models from the Alderis specification. DREAM also provides a way for random simulations that can be used efficiently to find bugs in designs that are too large and lead to state space explosions.\n\n\t\t\t\t\t\t
