Reactis V2011 Now Available

Cary, NC (June 23, 2011) -- Today Reactive Systems, Inc. announced the V2011 release of its Reactis® testing and validation package for Simulink®/Stateflow® models. The new version includes many new features and enhancements to both Reactis and the Reactis for C Plugin. Some highlights are as follows.


A simplified Reactis Tester launch dialog makes it even easier to generate tests from a model. The user may now specify how long automatic test generation should last by giving a maximum run time or maximum number of simulation steps to take while constructing the test vectors. The old launch parameters are also still available.

When running Reactis-generated tests either in Reactis Simulator or in Simulink using the runtests utility, Reactis compares the values computed by a model for top-level output ports and for test points against the values stored in the test suite for those items. Any differences are flagged. Reactis has always supported a global tolerance for performing these comparisons to avoid flagging small rounding errors. A new feature in V2011 enables the specification of a different tolerance for each output or test point.

A new search facility lets you perform a text search of your model for strings matching a pattern you specify. You can easily search Simulink block names and parameters, Stateflow state names and actions, Reactis Validator objective names, configuration variable names, and C code (if you are using the Reactis for C Plugin).

Additionally in V2011:

  • Model initialization speed is improved for some models.
  • Right-clicking on a system in the hierarchy panel offers an option "Copy System Path" which will copy the system path of that subsystem to the clipboard.
  • When extracting a subsystem, the user can select whether or not to include any triggering mechanism for the subsystem in the extracted model.

The following Simulink features are newly supported in V2011:

  • Initial support for MATLAB R2011a models.
  • Newly supported blocks: Rate Limiter, Function-Call Split, Function-Call Feedback Latch.
  • Support enumerated types and values in S-Functions and Legacy Code blocks.

Reactis for C Plugin

V2011 also includes a number of new features in the Reactis for C Plugin. Some highlights are as follows.

  • Comments and inactive C code within #ifdef statements are colored differently to differentiate them from exercised code.
  • Improved reachability analysis to identify and highlight dead code.
  • Allow (small) numeric arrays to be added as watched variables.
  • Produce a warning if:
    • the result of an expression with no side-effects is ignored.
    • a non-void function does not return a value.
    • __declspec and __attribute clauses are used.

About Reactis. Reactis provides automated test-generation and model-validation capabilities for Simulink/Stateflow models of control software. The tool can be used to test for conformance between a model and implementation code, and it can also be employed to validate model behavior. Reactis is used at dozens of companies worldwide in the automotive, aerospace, and heavy equipment industries.
