Integrating different tools to develop multiprocessor real-time systems

Presents a working environment for the development of real-time systems. This working environment is a collection of CASE tools, which are a heavy graphical orientation, intended for the specification, analysis, design and implementation of large and complex real-time systems. It enables a user to prepare, analyze and debug diagrammatic, yet precise, descriptions of the objects of the system under development from five interrelated points of view, capturing the environment, functionality, behavior, performance and hardware. These views are represented by a set of graphical languages, the most intricate of which are the tools of performance analysis, used to support the analysis of temporal behavior of systems for completeness, correctness, feasibility and predictability. In addition to the use of performance analysis tools, the main novelty of our working environment is in the fact that it can design real-time systems at different levels of granularity, carry out rigorous executions, simulations and animation of the described system, and create running code automatically.
