RATAN: A tool for rate analysis and rate constraint debugging for embedded systems

The increasingly complex design of embedded systems creates the problems of specifying consistent and satisfiable rate constraints on process execution rates, checking them for consistency and satisfiability, computing process execution rates, and debugging rate constraint violations. The high complexity of these problems requires a complete and automated framework to help the designer in producing correct systems in shorter design time. We present such a framework and its implementation in a tool called Ratan. Experiments on large benchmarks show the suitability of the tool for an interactive debugging environment.
