Signal Tracing

Visualize signal tracing by running the real-time application

Signal tracing lets you visualize real-time signals when you run a real-time application on the target computer. The signal tracing work flows provide options for selecting the signals for tracing and the selecting the way you view the signals.

To select signals for tracing, you can mark signals for logging by the Simulation Data Inspector, you can connect signals to a Simulink^® Scope block (for external mode simulation), or you can select signals in Simulink Real-Time™ Explorer to stream to the Simulation Data Inspector.

To view signals as you run the real-time application, you can open the Simulation Data Inspector or open the Simulink Scope block (for external mode simulation).

The advantage of tracing signals in the Simulation Data Inspector is that you can choose to save the run data for later review. Tracing signals by using the Simulink Scope block does not support saving the run data.
