Before you can analyze and preprocess the estimation data, you must assign the data to the model's channels. In order to assign the data, the Simulink® model must contains one of the following elements:
Top-level Inport block
Top-level Outport block
Logged signal. The logged signal can be a top-level signal in the model or a signal in the model subsystem.
To enable signal logging for a signal, in the Simulink Editor, select that signal, click the Record button arrow and click Log/Unlog Selected Signals. For more information, see Export Signal Data Using Signal Logging in the Simulink documentation.
In the Control and Estimation Tools Manager GUI, the rows in the Input Data tab correspond to the model's top-level Inport blocks.
Similarly, the rows in the Output Data tab correspond to either the top-level Outport blocks or logged signals in the model.
Adding an Inport or Outport block or marking a signal for logging creates a new row in the corresponding Input Data or Output Data tab. You can use the new row to import estimation data for the corresponding signal. To view the new row, click Update Task in the Estimation Task node of the Control and Estimation Tools Manager GUI.
