Review Data Logging and Visualization Setup: Ensure that your model's data logging and visualization configurations are compatible with real-time execution. This includes checking the sizes and dimensions of the data being logged and ensuring they match with what your scopes and logging utilities expect. Real-time systems may have specific requirements or limitations for data logging and visualization.
Synchronize Time and Data Sampling: Verify that the time base used for your model is correctly configured to match the data sampling rates. Mismatches between the sampling rates of different signals or between the model's time base and the data rates can lead to compatibility issues, as the system may be unable to correctly align data points with time steps.
Avoid Overloading the Communication Link: When executing models in real-time and visualizing data on Simulink scopes, there's continuous data exchange between MATLAB/Simulink and the Speedgoat target. Executing additional commands in MATLAB (like launching the help system) could temporarily strain this communication, potentially leading to errors. Try to minimize additional MATLAB tasks during critical real-time execution periods.
Consult Speedgoat Support: Since Speedgoat systems are highly specialized, reaching out to Speedgoat's technical support can provide specific advice and potentially a solution. They might be familiar with this issue and could offer a patch, configuration advice, or an update to resolve the problem.
Review Custom Code: If your model includes custom code or S-Functions, review them to ensure they properly handle data and time dimensions. Custom code that doesn't correctly manage data sizes or time steps could cause issues during real-time execution.
Increase Real-time Task Priority: In some cases, adjusting the priority of real-time tasks or the communication thread between MATLAB and Speedgoat might help. This is a more advanced and system-specific solution, so it should be done with caution and possibly with support from Speedgoat.
Check for Software Updates: Ensure that your MATLAB, Simulink, and Speedgoat firmware are up to date. Bugs or compatibility issues are resolved in newer versions of the software or firmware.
