NDLI: Constructing abstract models of concurrent real-time software

Content Provider	ACM Digital Library
Author	Corbett, James C.
Abstract	Concurrent real-time software is used in many safety-critical applications. Assuring the quality of such software requires the use of formal methods. Before a program can be analyzed formally, however, we must construct a mathematical model that captures the aspects of the program we want to verify. In this paper, we show how to construct mathematical models of concurrent real-time software that are suitable for analyzing the program's timing properties. Our approach differs from schedulability analysis in that we do not assume that the software has a highly restricted structure (e.g., a set of periodic tasks). Also, unlike most more abstract models of real-time systems, we account for essential properties of real implementations, such as resource constraints and run-time overhead.
