This paper presents a formalism‐based methodology and its implemented environment which constitutes a sound framework for real‐time systems development. The software and/or hardware systems developed in such a formal manner are wellstructured and maintainable. We first propose a set‐theoretic VSSS (Variable Structure System Specification) formalism. This formalism is the core of the presented methodology which supports a means of formal specification for real‐time systems. We then develop the environment, including VSSS language definition, a translator for the language, and supporting libraries for real‐time execution. Finally, a demonstration of the methodology in development of a real‐time event manager, a subsystem of an ATM‐based communication system, shows the correctness and efficiency of the methodology.
