  • Reactis V2004 Now Available.
  • Reactive Systems to Exhibit at SAE World Congress.


We are pleased to announce the availability of Reactis V2004, which includes numerous new features and enhancements since the previous major release in October of 2003. Some highlights are below. For more details please see the Reactis User's Guide in the distribution and also available from

  • Reactis can now automatically extract subsystems from models. This feature facilitates the decomposition of a large model into smaller pieces for test-generation and validation. The utility is invoked by right-clicking on a subsystem in the main Reactis window and selecting ``Extract Subsystem.''
  • Reactis now supports the fixed-step solver as well as the variable-step solver for Simulink/Stateflow models.
  • A new License Monitor utility enables users to monitor available Reactis licenses across various servers without starting Reactis.
  • In Reactis Simulator, breakpoints can now be set on individual Simulink blocks or Stateflow transitions and states by right-clicking on the item and selecting ``Toggle Breakpoint.''
  • The analysis that Reactis employs to detect unreachable model elements has been improved.
  • The performance of model initialization has been improved.

This is installment twelve of ``The Reactis Communicator'', a low volume mailing list for conveying information about Reactis, RSI's embedded software design automation tool suite. Reactis enables users to deploy model-based software testing and validation to dramatically reduce the costs of testing embedded control software. The tools are designed for use in conjunction with the Simulink and Stateflow modeling and simulation environments offered by The MathWorks, Inc.

If you are no longer interested in receiving information about Reactis, please see the instructions below for removing yourself from the list and we apologize for the intrusion.
