This poster presents a design language and a tool suite covering the development life-cycle of a Sense/Compute/Control (SCC) application. This language makes it possible to define the architecture of an application, following an architectural pattern commonly used in SCC applications. Our underlying methodology assigns roles to the stakeholders, providing separation of concerns. Our tool suite includes a compiler that takes design artifacts written in our language as input. The compiler generates customized support for subsequent development stages, namely implementation and test. In doing so, it ensures the conformance between the architecture and the code. Our tool suite also includes a simulator for testing SCC applications, without requiring code modification. Our methodology has been applied to a wide spectrum of areas, such as building automation, advanced telecommunications, and health-care.
