REACTIS V2004.2 NOW AVAILABLE
We are pleased to announce the availability of Reactis V2004.2, which
includes numerous new features and enhancements since the previous
major release in March of this year. Some highlights are below. For
more details please see the Reactis User's Guide which is included in
the distribution and is also available from:
The following features were added since V2004.
Support for single precision floating point arithmetic.
- Support for the MATLAB R14 (Simulink 6.0) file format.
- Support for Boundary Value Coverage to track whether an inport
assumes the boundary values of its domain of possible values.
- A new model import architecture that vastly simplifies the preparation
of models for use with Reactis. Benefits include improved error
messages and the elimination of type errors reported by
Reactis but not by Simulink.
- Optimizations in Reactis Simulator to increase the size
of both models and test suites that the tool can handle.
- Support for data objects in Simulink block parameters.
- A capability to export test suites as MATLAB .mat files.
This binary format enables values in tests to be represented with more
precision than is possible in the ASCII-based .m file format. When
running a Reactis-generated test suite on a Simulink model, the
higher precision of test data helps avoid some rounding errors.
- Precision improvements for models with S-Functions and models that
use MATLAB. This higher precision eliminates rounding error in
- A capability to view which users occupy shared licenses.
- Improved dependency-cycle detection and reporting. The reporting
of certain falsely detected dependency cycles was eliminated and
error reporting related to cycles was improved (especially when
cycles are due in part to user-specified block priorities).
- General performance improvements.
- An improved
File -> Synchronize operation in the
Reactis Info File Editor.

MODEL-BASED TESTING WITH REACTIS AT NISSAN.
A recent article published on The MathWorks website describes how a
Model-Based Design process that includes Reactis helped Nissan reduce
by 50% the development time for an advanced emissions control system.
The article is available at:
REACTIVE SYSTEMS LOGS STRONG GROWTH IN 2004.
We are pleased to report strong sales growth for Reactis during 2004.
The number of companies using Reactis has more than doubled while the
number of active licenses has more than tripled. Customers in the
automotive industry now include five of the world's top six OEMs as
well as many Tier 1 suppliers. Reactis also logged its first sales in
the aerospace sector in 2004. The automatic generation of MC/DC test
data by Reactis is expected to help aerospace users dramatically
reduce certification costs.
JAPANESE LOCALIZATION OF REACTIS ENTERS BETA TEST.
We are pleased to announce that a preliminary version of Japanese
language support in Reactis will be available starting with beta
version V2004.3 due out next week.
NEW MAILING LIST WILL ANNOUNCE REACTIS PATCHES.
As a number of you have requested, we have created a new mailing list
on which we will announce the release of all Reactis patches. The
Reactis Communicator list (this one) will still announce major
releases, while the new one will have more frequent postings to
describe all bug fixes and new features as they are released with each
patch. If you would like to join the mailing list, please send
an email message to firstname.lastname@example.org (no
subject or body content are required in the message).
The Reactis Team
This is installment thirteen 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,
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.
