Chi is a modeling language for describing and analyzing performance of discrete event systems by means of simulation. It uses a process-based view, and uses synchronous point-to-point communication between processes. A process is written as an imperative program, with a syntax much inspired by the well-known Python language.
Chi is one of the tools of the Eclipse ESCET™ project. Visit the project website for downloads, installation instructions, source code, general tool usage information, information on how to contribute, and more.

The Eclipse ESCET project, including the Chi language and toolset, is currently in the Incubation Phase.
