MathWorks updates to  Simulink Real-Time enhance rapid control prototyping and hardware-in-the-loop (HIL) testing with Model-Based Design.

In Release 2020b, Simulink Real-Time has been enabled with the QNX Neutrino RTOS, a multi-process 64-bit POSIX-compliant real-time operating system from BlackBerry.

The QNX RTOS is widely used in life and safety-critical systems for vehicles, medical devices, industrial controls, rail, robotics and aerospace & defense.

The update builds on the existing Simulink Real-Time and Speedgoat integration, enabling engineers to extend their Simulink models with I/O driver blocks, automatically build real-time applications, create instrumentation, and perform interactive or automated runs on a target computer.

Engineers can replace a physical system such as a vehicle, aircraft, or robot with a real-time simulation of a virtual system to reduce the cost of testing. The QNX Neutrino RTOS enables new workflows, making real-time computing problems easier to solve, particularly when multiple tasks compete for a system’s resources.

The downloadable Simulink Real-Time Target Support package includes development tools and run-time components, including a cross-compiler provided at no additional cost, to compile and run real-time applications.

 Additional capabilities now available in Simulink Real-Time include:

• New Simulink Real-Time Explorer and graphical instrument panels and applications: Control and configure a real-time application with a new Simulink Real-Time Explorer, and use App Designer to create graphical instrument panels and custom applications
• Support for test engineering workflows: Develop test and calibration apps and scripts that interact with a real-time application using only MATLAB and Simulink Real-Time
• Upgrade Advisor for Simulink Real-Time: Automatically upgrade models created in prior versions to take advantage of the new 64-bit RTOS
• New File Log block: Enable and disable logging during real-time execution, log multiple runs while disconnected from MATLAB, and import logged data to MATLAB
