Main Content

To import, visualize, and map signal and bus data to root-level input ports, use the Root Inport Mapper tool or the getRootInportMap function. At the top level of a model or referenced model, root-level input ports include:

• Inport blocks
• Enable blocks
• Trigger blocks

Root-level input ports import data from the MATLAB® workspace based on the value of the > > parameter.

Root-level inport mapping imports signal data in a way that meets most modeling requirements and maintains model flexibility. You can:

• Test your model with signals from the workspace and use your model as a referenced model in a larger context without any modification.
• Update the Input parameter based on the signal data you import and map to root-level inports.
• Visually inspect signal data without loading all the data into MATLAB memory.

Tip

To determine whether another data import technique meets your specific modeling requirements (such as the amount of data or the storage location) better, see Comparison of Signal Loading Techniques.

Command-Line Interface

You can use the [getRootInportMap](../slref/getrootinportmap.html) to create a custom object to map signals to root-level input ports and [getSlRootInportMap](../slref/getslrootinportmap.html) to create a custom map mode. For more information, see Create and Use Custom Map Modes.

Import and Mapping Workflow

1. Identify and possibly create signal data to import and map.
2. Import and View and Inspect Signal Data.
3. Map the imported signal data. For example, you can map the signal data by block path or signal name.
4. Simulate the model using the mapped data. After associating a scenario with the model, you can generate scripts for simulation with scenarios to perform batch simulations.
5. Optionally, save the current Root Inport Mapper scenario for future reference or to share with other people.

Tip

To extend the Root Inport Mapper tool map modes, you can create a custom mapping file function to map data to root-level inports.

View and Inspect Signal Data

After you import signal or bus data, you can view and inspect signal data using tools such as:

• Signal Editor
• Simulation Data Inspector
• The Simulink.SimulationData.Dataset or Simulink.SimulationData.DatasetRef plot method.

For a summary of the other steps involved in using the Root Inport Mapper tool, see Import and Mapping Workflow.
