We describe InterPlay, a simulation engine coordinator that supports cooperation and
interaction of multiple simulation and execution tools, thus helping to scale-up the design
and development cycle of reactive systems. InterPlay involves two main ideas. In the first, we
concentrate on the inter-object design approach involving LSCs and the Play-Engine tool,
enabling multiple Play-Engines to run in cooperation. This makes possible the distributed
design of large-scale systems by different teams, as well as the refinement of parts of a …

(LSCs) and its support tool, the play-engine, enabling multiple play-engines to run in
