Reactis V2006 Now Available
We are pleased to announce the availability of Reactis V2006, which
includes numerous new features and enhancements since the previous
major release in May of 2005. Some highlights are below.
For more details please see the revision history in the Reactis User's
Guide which is included in the distribution and is also available
The following are some of the features added since V2005.
New Test Suite File Format
The V2006 Reactis release introduces a new file format for test suites
(.rst files). The new format allows Reactis to access a test
suite directly on disk instead of requiring the entire suite to be
loaded in memory. The format enables Reactis to manipulate
dramatically larger test suites. The new capability is especially
useful when importing very large test suites created outside of Reactis.
The new format also enables several other new features
including the following:
- Tests may now have user-specified names.
- Detailed logs for each test and the suite as a whole are
maintained by Reactis.
When loading a test suite stored in the pre-V2006 format, the test
suite will be automatically converted to the new format.
Test suites can also be exported to the pre-V2006 format.
New Tools for Covering Timer Conditions
Creating tests that cause interruptible timer conditions to reach
their end value is often a challenge. An interruptible timer
condition is a model variable that changes its value from a start
value to an end value by some increment. In such cases, it is often
possible for the variable to be reset to its start value as the system
executes. V2006 includes several new features to assist you in
creating tests that cause timer conditions to reach their end values.
Enhanced Model Navigation
Dragging with left mouse button in the main window will now scroll
- When hovering over an item in the hierarchy panel that
is a child of the system currently displayed in the main
panel, Reactis now highlights child in the main window.
- Added a Go to Parent button to the Reactis toolbar.
License Manager Enhancements
- The Reactis License Manager may now be configured to log
license usage to two different locations: the Windows Application
Event Log and a log file. The logs include information about
when licenses are granted and released as well as who occupies
- In the User Info tab of the Settings dialog,
an option is now available to automatically set the name
field to the Windows username of the person currently
The API now uses MATLAB version as set in the Reactis GUI.
- Added file libreactis_lcc.lib to API. This enables
applications using the Reactis API to be compiled
using the default compiler distributed with MATLAB.
Newly-Supported Simulink / Stateflow Features
V2006 adds support for many new Simulink blocks and features.
Some of these are listed below.
- Support for Look-Up-Table Dynamic blocks.
- Support Simulink Signal Viewer Scopes.
- Support Simulink From Workspace, From File and Signal Builder
- Support for exporting Stateflow graphical functions from a
- Support models created with MATLAB R14.3. Not all new
features of R14.3 are supported yet.
- Support for alias types created with Simulink.NumericType or
Simulink.AliasType. These alias types are now supported both in
Simulink and Stateflow. Alias types are dereferenced and show up
in Reactis as the native Simulink base types.
- Configuration variables of type array and structure are now
- Reactis now flags a number of different types of modeling
constructs that can lead to unexpected behavior.
- If an error occurs during test generation, Tester will add the
current test (which caused the error) to the test suite before terminating.
- Added a Forward button to the Tester launch dialog that
allows the user to return to the Tester results dialog after
- Allow import of test suites (.rst files) that do not exactly
match the current model. This can be achieved by selecting the
Test Suite -> Import menu item and then selecting a test
suite file. Types will be adapted and ports and configuration
variables added or removed to fit the current model.
- In user guided simulation mode, provide a menu to switch
all inputs to Random or Entry mode at once.
- Show current step number when in user-guided or random simulation mode.
- Improved the type editor dialog when editing array types.
The dialog now handles 2-dimensional arrays and includes a
capability to copy and paste type-specifications for the elements
of the array.
- Track branch coverage for Relay blocks.
- In Simulator, when one or more tests are selected to be run,
the number of steps entry box in the toolbar will be pre-filled
with the number of steps selected.
- When choosing configuration variables, the list of workspace
data items is now sorted alphabetically.
- Tester now obtains better boundary value coverage for vector inputs.
RSI Logs Strong Growth in 2005
We are pleased to report that 2005 was a good year for Reactis.
The number of companies using Reactis almost doubled and, due to
strong growth within existing customers, active licenses more than
doubled. Use of Reactis increased in both the automotive and
Model-Based Testing with Reactis at Azure Dynamics
A recent article published on The MathWorks website describes how a
Model-Based Design process that includes Reactis helped Azure Dynamics
achieve a level of test coverage "reserved for highly regulated industries."
The Azure team uses Reactis in the development of hybrid-electric and
electric powertrain applications.
The article is no longer available on the MathWorks site.
Revamped Reactis FAQs Now Available
A new version of the Reactis FAQs is now available from the RSI
website. It has been reorganized for easier navigation and includes
numerous new questions and answers. Please keep the questions
coming... The FAQs may be found at:
Jump-Start Reactis Deployment with On-Site Training
Reactive Systems now offers one- and two-day Reactis training courses
delivered by a qualified instructor at your site. The hands-on courses
include numerous exercises to introduce engineers to model-based
testing and validation with Reactis. No prior experience with Reactis
is required. For more information on the cost-effective way to spread
the benefits of Reactis within your organization, please send email to
email@example.com or call 703-534-6458.
The Reactis Team
This is installment sixteen 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,
