Model-Driven Development of High-Integrity Distributed Real-Time Systems Using the End-to-End Flow Model

Building High-integrity Distributed Real-Time (HDRT) systems requires a rigorous methodology to assist in the design and development of verifiable software. This paper describes an approach based on the Model-Driven Engineering (MDE) paradigm to ease the automatic generation of HDRT applications from high-level system models. Since those applications must be amenable to stringent timing analysis, such as the determination of worst-case execution time or schedulability analysis, we present the integration of a set of timing analysis tools with a toolset for MDE. In addition, this paper explores a new approach to integrating the real-time end-to-end flow model with the automatic generation of Raven scar-compliant source code in distribution middleware.
