Simulink Real-Time went through a major product update in the R2020b release. As part of this, a new "Test Engineer" license model was introduced: Simulink, MATLAB Coder, and Simulink Coder are no longer required if you don't need to modify and rebuild the real-time application MLDATX file.
The following workflows require only MATLAB and Simulink Real-Time to be installed and licensed on the host computer:
1. Simulink Real-Time Explorer
The easiest interactive way to interact with a real-time application, without extra development effort, is by using the Simulink Real-Time Explorer GUI:
2. MATLAB API for Simulink Real-Time
To develop a custom script using MATLAB code, or interact with a real-time application from the MATLAB command window, the the following APIs are available:
- Install, load, start, or stop real-time applications: 'slrealtime' target object
- Apply Input Stimulation: Target.Stimulation (R2021a+)
- Tune Parameters: setparam or Parameter Sets (R2021a+)
- Signal Logging & Live Streaming: Simulation Data Inspector, instrument objects, and start/stopRecording API (R2022a+)
- Import and Visualize File Logs: Target.FileLog.import
3. MATLAB App
The recommended way to create a fully customizable GUI to interact with applications on Speedgoat is with MATLAB App Designer. Using App Designer gives you access to the full MATLAB API for Simulink Real-Time as mentioned in item 2. To facilitate the app development, use the handy automatic App Generator (R2022a+) and dedicated Simulink Real-Time App Components (R2021b+). For more information, see:
- How can I create an SLRT app with App Designer to control, tune, and monitor my real-time application running on a Speedgoat computer?
- Create App Designer Instrument Panels by Using App Generator
4. MATLAB Engine API
You can write a script or design GUIs in languages like C#, C/C++, or Python using MATLAB External Language Interfaces. This method also gives you access to the full MATLAB API for Simulink Real-Time as mentioned in item 2. For more information, see:
5. Simulink Real-Time ASAM XIL API (R2021b+)
Starting from R2021b, you can interface Simulink Real-Time models with automatic test cases from third-party software that supports the ASAM XIL API, for example, TraceTronic ECU-TEST or Synopsys TPT (previously "PikeTec TPT"). To use this workflow, you need to install the Simulink Real-Time XIL API support package. It provides an API that allows control of real-time applications using a C# program.
