Synchronous languages have been introduced in the 80s to program reactive systems. Such systems are characterised by their continuous reaction to their environment, at a speed determined by the latter. Synchronous languages have recently seen a tremendous interest from leading companies developing automatic control software for critical applications. For instance, Schneider Electric uses a Lustre-based tool, named Scade, to develop the control software for nuclear plants. Aerospatiale also uses this tool to develop the flight control of the new Airbus planes. Dassault Aviation uses Esterel Studio to program the flight control software of the Rafale fighter. Snecma uses Sildex, a Signal-based tool to develop airplane engines. ST Microelectronics, Texas Instrument, Motorola, Intel, are also interested in the Esterel technology for chip design. The key advantage pointed by these companies is that the synchronous approach has a rigorous mathematical semantics which allows the programmers to develop critical software faster and better.
Indeed, the semantics of the languages is used as formal model upon which all the programming environments are defined. The compilation involves the construction of these formal models, and their analysis for static properties, their optimisation, the synthesis of executable sequential implementations, the automated distribution of programs. It can also build a model of the dynamical behaviours, in the form of a transition system, upon which are based the analysis of dynamical properties, e.g., through model-checking based verification, or discrete controller synthesis. Hence, synchronous programming is at the cross-roads of many approaches in compilation, formal analysis and verification techniques, and software or hardware implementations generation.The approach is related to formal methods for reactive systems like Statecharts, StateFlow, UML StateCharts.
After SLAP 2002 in Grenoble, SLAP 2003 is the second workshop devoted entirely to synchronous languages, applications, and programming. It will take place on July 1st 2003, in Porto (Portugal), as a satellite event of ECRTS 2003. Its purpose is to bring together researchers and practitioners who work in the field of reactive systems.
The workshop topics cover the following issues:
This year's (non-exclusive) focus will be on implementation aspects, especially:
The format of the workshop will feature technical presentation and also a significant time for discussion, e.g., on the basis of a challenge problem session open to different technical approaches. Judging from the previous SLAP 2002 and the annual Workshop on Synchronous Programming, the expected number of participants should be around 30.
