Argos: imperative synchronous language developed at Verimag. Argonaute: programming environment based on it, with compiler and some connections to verification tools. Aim: study, implement 2 mixed languages: Argos + Esterel/Lustre.

A set of tools for the specification, verification, and implementation of reactive systems. It includes a compiler for synchronous programs, a symbolic model checker, and a tool for hardware/software synthesis. Downloadable in binary form for Linux (i586).

By R.J. Wieringa; Morgan Kaufmann, 2002, ISBN 1558607552. Shows how techniques and approaches of 3 most popular design methods can be mixed in flexible, problem-driven way; more examples on companion website. [Morgan Kaufmann]

Declarative synchronous language, kernel language of SCADE (was SAO+/SAGA) industrial environment developed by Esterel Technologies; a description is a set of equations that must be verified always by program variables. [Verimag]

Graphical formalism (name of model, a syncChart is an instance) dedicated to reactive system modeling. Many features inherited from StateCharts, Argos. Brief introduction, related publications, distribution, downloads.

Languages and reactive systems laboratory: research topics, papers, tools, people, industrial and academic cooperations, projects/contracts. France.

Nicolas Halbwachs; Kluwer Academic Publishers, 1992, ISBN 0792393112. Presents synthesis of recent works on reactive system design, a term introduced to avoid ambiguities often involved with term realtime. [Kluwer]

Abstract on paper on reactive kernels making the central, hardest part of reactive systems; Esterel is not full language, it is a program generator used to program reactive kernels as YACC programs parsers from grammars. [ResearchIndex]

To program synchronous reactive systems, made by merging 3 existing synchronous languages (Lustre, Esterel, Argos) by uniform translation rules to a common intermediate format called Boolean automata. Paper, PDF format.

For this declarative language, for realtime uses: reactive, embedded systems. Synchronous languages are opposite to the asynchronous types, as in C, Ada. Five chapters. Paper, PDF format.

Thesis proposing parallel language, based on C, that lets programmers explicitly specify and manage parallelism on a broad class of architectures. [Purdue University]
