GRL: A Specification Language for Globally Asynchronous Locally Synchronous Systems

  • Conference paper

Part of the book series: Lecture Notes in Computer Science ((LNPSE,volume 8829))

Abstract

A GALS (Globally Asynchronous, Locally Synchronous) system consists of several synchronous subsystems that evolve concurrently and interact with each other asynchronously. Most formalisms and design tools support either the synchronous paradigm or the asynchronous paradigm but rarely combine both, which requires an intricate modeling of GALS systems. In this paper, we present a new language, called GRL (GALS Representation Language) designed to model GALS systems in an abstract and versatile manner for the purpose of formal verification. GRL has formal semantics combining the synchronous reactive model underlying dataflow languages and the asynchronous concurrent model underlying process algebras. We present the basic concepts and the main constructs of the language, together with an illustrative example.

This work was partly funded by the French Fonds unique interministériel (FUI), Pôle Minalogic (project “Bluesky for I-Automation”).
