Export Signal Data Using Signal Logging (Simulink)

To capture signal data from a simulation, you can use signal logging. Mark the signals that you want to log and enable signal logging for the model.

Configure a Signal for Logging (Simulink)

Mark the signals that you want to log simulation data for.

Enable Signal Logging for a Model (Simulink)

To log signals marked for signal logging, set the Signal logging configuration parameter.
