Press Room - Latest Press Releases

The MathWorks today announced the release of SystemTest, a software product that provides a framework for engineers to develop and automate testing for verifying algorithms and models using Model-Based Design .  SystemTest manages and streamlines the testing process for system development by enabling continuous verification and validation starting at the specification and design phase.  Using SystemTest, engineers can produce validated systems faster, reach product performance goals, shrink design times, and decrease time-to-market for even the most sophisticated system designs.

Engineers in the aerospace, automotive, defense, and communications industries can use the integrated simulation and test environment that SystemTest provides as a consistent testing framework for Model-Based Design.  Because the framework handles design and software testing, engineers can reuse the tests they create early in the development process throughout their development process, reducing development effort.  Additionally, test reuse ensures standard and repeatable verification throughout the workflow, increasing a product or design's quality by ensuring a consistent process.  These capabilities allow engineers to find errors earlier in the development process when they are less costly and easier to fix. 

"There have been instances where we have run as many as hundreds of thousands of simulations at a time to analyze and validate our Simulink ® models," said Ollen Landrum, development manager at the National Air and Space Intelligence Center.  "With SystemTest, we can not only automate our parameter sweep runs on one of our more challenging systems, but do so at a significantly faster rate.  Process times that once took two weeks can now be done in 30 minutes."

The MathWorks SystemTest provides engineers with a framework for setting up and executing tests, managing input/output data, and analyzing results.  The framework's ability to sweep parameters allows users to easily analyze multi-dimensional datasets, and gives designers a complete picture of the system being tested.  The framework also provides the ability to reload the results of simulations and measurement sequences for further analysis and comparison. 

"Engineers today are designing more complex systems then ever before.  At the same time, demands for decreased time-to-market are on the rise," said Brett Murphy, manager, technical marketing for The MathWorks.  "SystemTest, coupled with Model-Based Design, addresses these issues by providing a single environment for the continuous testing of specifications, designs and software at every stage of development -- from concept to production implementation."
