Map Root Inport Signal Data
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:
Root-level input ports import data from the MATLAB® workspace based on the value of the Configuration Parameters > Data Import/Export > Input 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.
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.
Open the Root Inport Mapper Tool
Use either of these approaches to open the Root Inport Mapper tool:
In the Configuration Parameters > Data Import/Export pane, click Connect Inputs.
In the block parameters dialog box for the Inport block, select Connect Inputs.
You can use the
to create a
custom object to map signals to root-level input ports and
to create a custom map mode. For more
information, see Create and Use Custom Map Modes.
Import and Mapping Workflow
Map the imported signal data. For example, you can map the signal data by block path or signal name.
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.
Optionally, save the current Root Inport Mapper scenario for future reference or to share with other people.
To extend the Root Inport Mapper tool map modes, you can create a custom mapping file function to map data to root-level inports.
Choose a Map Mode
To specify how you want the Root Inport Mapper tool to map the signal data to a model, select from these map modes in the Map Configuration section of the toolbar:
Block name — Connect signal data to ports based on the name of a root-level input port block.
Block path — Connect signal data to ports based on the path of a root-level input port block.
Signal name — Connect signal data to ports based on the name of the signal on a port.
Port order — Connect sequential port numbers to the imported data.
Custom — Connect signal data to ports based on the definitions in a custom mapping file.
Each supported input format supports one or more map modes. To import MATLAB
timeseries data, for example, you use any map mode. To import data array
signal data, use the port order map mode.
