MathWorks has added a fault analyzer and polyspace code testing to the latest release of its Simulink and Matlab tools.   

Release 2023b (R2023b) includes the Simulink Fault Analyzer for systematic fault effect and safety analysis using simulation.

The new product performs fault injection simulations without modifying engineering designs so that engineers time or trigger faults by specific system conditions and can perform safety analyses, such as Failure Mode and Effects Analysis (FMEA), in simulation. This also helps engineers create and document formal connections between faults, hazards, fault detection and mitigation logic, and other artifacts when paired with Requirements Toolbox.

R2023b also includes Polyspace Test, a new product that empowers engineers to develop, manage, and execute C and C++ code tests in embedded systems. Users can create stubs and mocks to isolate and verify components under test using the Polyspace xUnit API or a graphical test authoring editor. Polyspace Test also lets engineers execute tests on host computers or embedded targets, automate test execution, and link tests to requirements for traceability.

 R2023b also includes an Aerospace Toolbox to propagate and visualize orbits of satellite constellations and to perform line-of-sight (LOS) and eclipse analyses and wireless engineers can design and implement 5G, satellite, WLAN, and custom OFDM-based communication subsystems for FPGAs, ASICs, and SoCs with Wireless HDL Toolbox. The DO Qualification Kit allows aerospace engineers to qualify Polyspace Test according to DO-178C and DO-330 Standards.

 A Predictive Maintenance Toolbox now extracts physics-based features from motors and rotating machinery while a Signal Integrity Toolbox allows engineers to automate simulations, analyze data, and create visualizations from the Matlab command line.

 The Simulink Desktop Real-Time can execute real-time tests from Linux desktop computers while the Wavelet Toolbox enables engineers to apply wavelet and time-frequency analysis using apps. The toolbox also now uses automatic feature extraction for AI workflows.

“The growing complexity of design models makes simulation a critical engineering tool,” said MathWorks Director of Technical Product Marketing Dominic Viens. “R2023b’s new products and updates were built to simplify Model-Based Design and help engineers and researchers deliver their best work.”
