Idioms for /spl mu/-charts

Abstract

This paper presents an idiomatic construct for /spl mu/-charts which reflects the high-level specification construct of synchronization between activities. This, amongst others, has emerged as a common and useful idea during our use of /spl mu/-charts to design and specify commonly-occurring reactive systems. The purpose of this example, apart from any inherent interest in being able to use synchronization in a specification, is to show how the very simple language of /spl mu/-charts can used as a basis for a more expressive language built by definitional extension.
