Press Room - Latest Press Releases

The MathWorks today announced a new version of SystemTest, its test management and analysis software for system verification and validation.

Engineers can now automatically distribute independent tests or simulation runs of Simulink® models to multiple processors, without requiring manual coding, because SystemTest 2 works seamlessly with Distributed Computing Toolbox, also from The MathWorks. The enhancements in SystemTest 2 dramatically reduce the time needed for testing, leading to faster production of high-quality system designs.

SystemTest 2 is especially useful for engineers who run multiple iterations of Simulink models. Previously, to leverage the computing power of multiprocessor environments, these engineers needed to hand-code scripts to distribute Simulink test cases to each processor, which is a time-intensive and error-prone process.

With SystemTest 2 and Distributed Computing Toolbox, users can automate the distribution of Simulink tests to up to four simultaneous Simulink sessions on one machine through a simple graphical user interface. Engineers who have MATLAB® Distributed Computing Engine can also take advantage of multiple processors in a computer cluster, using the same simple interface. By distributing test cases to multiple processors and eliminating hand-coding, the total test can be conducted more quickly and accurately.

“Multicore, multiprocessor technology has advanced at a rapid pace in recent years, providing tremendous opportunity to the engineers and system designers who can find effective ways to harness its potential,” said Brett Murphy, technical marketing manager for verification, validation, and test at The MathWorks. “With SystemTest 2, we’re enabling our customers to apply the power of computing clusters to their verification and validation efforts, resulting in time and quality gains bound only by the number of processors they can access.”

The distributed computing features in SystemTest 2 build on the tool’s capabilities for developing and executing tests for MATLAB algorithms and Simulink models. With SystemTest 2, engineers are provided a framework for setting up and executing tests, managing input/output data, and analyzing results. The tool efficiently analyzes multidimensional data sets to give designers a complete picture of the system being tested. SystemTest 2 also provides the ability to reload the results of simulations and measurement sequences for further analysis and comparison.
