Analyzing Partially-Implemented Real-Time Systems

—Most analysis methods for real-time systems assume that all the components of the system are at roughly the same stage of development and can be expressed in a single notation, such as a specification or programming language. There are, however, many situations in which developers would benefit from tools that could analyze partially-implemented systems, those for which some components are given only as high-level specifications while others are fully implemented in a programming language. In this paper, we propose a method for analyzing such partially-implemented real-time systems. Here we consider real-time concurrent systems for which some components are implemented in Ada and some are partially specified using regular expressions and Graphical Interval Logic (GIL), a real-time temporal logic. We show how to construct models of the partially-implemented systems that account for such properties as run-time overhead and scheduling of processes, yet support tractable analysis of non...
