Graphically Manage Shared Interfaces, Data Types, and Constants

The Architectural Data section of a Simulink® data dictionary enables interfaces, data types, and constants to be authored, managed, and shared between components and compositions modeled in Simulink. The Architectural Data section provides scalability for system-level and multicomponent designs by containing these shared elements in a central location. For programmatic workflows related to the Architectural Data section, see Create Architectural Data Object and Use It to Configure Architectural Data.

You can configure architectural data and apply your changes to a model using this basic workflow:

  1. Create a data dictionary.

  2. Design interface, data types, and constants with the Architectural Data Editor.

  3. Link the data dictionary containing architectural data to a Simulink or architecture model.

Create Simulink Data Dictionary and Open Architectural Data Section for Editing

To create a data dictionary programmatically, see Store Data in Dictionary Programmatically or Create Architectural Data Object and Use It to Configure Architectural Data.

To create a data dictionary outside the context of a model open Model Explorer. From the toolbar select File, New, and then Data Dictionary.

Model Explorer with Data Dictionary option selected.

To create a data dictionary from a Simulink model:

  1. Open the f14 model, which loads design data into the base workspace.

  2. Save a copy of the model to your working folder location. Open the copy.

  3. In the Simulink Editor, on the Modeling toolstrip, open the Design menu, select Link to Data Dictionary.

  4. In the Model Properties dialog box, select New to create a data dictionary.

    Model Properties of f14 model.

  5. Name the data dictionary, save it, and click Apply.

Design Data Types, Interfaces, and Constants Using Architectural Data Editor

Once you create your data dictionary, you can add and edit architectural data using the Architectural Data Editor. This tool allows you to author elements shared outside of the context of a particular component or composition and allow multiple team members to define and manage these elements.

Open Architectural Data Editor

To open the editor from a Simulink model already linked to a data dictionary:

  1. In the bottom left of the model, select the Model data icon Model data, and then select External Data. This opens Model Explorer.

  2. In Model Explorer select the Architectural Data node to expose and select the Open Architectural Data Editor button.

    Model Explorer with the architectural data node selected.

To open the editor from outside the context of a model, use one of these methods:

  • In the MATLAB® Current Folder browser, navigate to and double-click the .sldd file to open Model Explorer. Expand the data dictionary file and select Architectural Data, then click Open Architectural Data Editor from the Dialog pane.

  • Use the show function on an Architectural Data object created using Simulink.dictionary.archdata.create or

  • Enter archdataeditor at the MATLAB command line.

The standalone Architectural Data Editor with an interface selected. The Code Generation section includes the Data scope property Auto.

Add and Configure Data Using Architectural Data Editor

With the Architectural Data Editor, you can create, configure, and manage architectural data.

  • Create — On the toolstrip, in the Create section, add data type definitions, interfaces, and constants. Data types, interfaces, and constants each have a dedicated tab for data management.

  • Configure — In the right panel, use the Details pane to configure your data. The Details pane can also display platform-specific properties.

    For example, when you open a Simulink data dictionary linked to a model that is mapped to a Native platform, the Details pane displays a Code Generation pane. You can then define Data scope and Header file. For more information on how to determine these settings, see Control File Placement of Custom Data Types (Embedded Coder). To preserve dimensions of bus objects that contain multidimensional bus elements, select the Preserve element dimensions option.

  • Manage — You can filter, sort, and search data on the Interfaces, Data Types, and Constants tabs.

Link Data Dictionary to Model

To link an existing data dictionary from the Simulink model toolstrip, on the Modeling tab, open the Design gallery and select Link to Data Dictionary. In the Model Properties dialog box, click Browse to select a data dictionary. Select Apply then OK.
