Import and Export Architectures

Open Script

This example shows how to import and export Architectures. In System Composer, an architecture is fully defined by three sets of information:

  • Component information

  • Port information

  • Connection information

You can import an architecture into System Composer when this information is defined in, or converted into, MATLAB tables.

In this example, the architecture information of a simple UAV system is defined in an Excel spreadsheet and is used to create a System Composer architecture model. You can modify the files in this example to import architectures defined in external tools, when the data includes the required information. The example also shows how to export this architecture information from System Composer architecture model to an Excel spreadsheet.

Architecture Definition Data

You can characterize the architecture as a network of components and import by defining components, ports, connections, and interfaces in MATLAB tables. The component table must include name, unique ID, and parent component ID for each component. It can also include other relevant information such as referenced model, stereotype qualifier name and so on. required to construct the architecture hierarchy. The port table must include port name, direction, component, and port ID information. Port interface information may also be required to assign ports to components. The connection table includes information to connect ports. This includes, at a minimum, connection ID, source port ID, and destination port ID.

The systemcomposer.importModel(importModelName) API :

  • Reads stereotype names from Component table and load the profiles

  • Creates components and attach ports

  • Creates connections using the connection map

  • Saves referenced models

  • Saves the architecture model

Make sure the current directory is writable because this example will be creating files.

[stat, fa] = fileattrib(pwd);
if ~fa.UserWrite
    disp('This script must be run in a writable directory');
    return;
end
% Instantiate adapter class to read from Excel.
modelName = 'simpleUAVArchitecture';
% importModelFromExcel function reads the Excel file and creates the MATLAB
% tables.
importAdapter = ImportModelFromExcel('SmallUAVModel.xls','Components','Ports','Connections','PortInterfaces');
importAdapter.readTableFromExcel();

Import an Architecture

model = systemcomposer.importModel(modelName,importAdapter.Components,importAdapter.Ports,importAdapter.Connections,importAdapter.Interfaces);
% Auto-arrange blocks in the generated model
Simulink.BlockDiagram.arrangeSystem(modelName);

Export an Architecture

You can export an architecture to MATLAB tables and then convert to an external file

exportedSet = systemcomposer.exportModel(modelName);
% The output of the function is a structure that contains the component table, port table,
% connection table, and the interface table.
% Save the above structure to excel file.
SaveToExcel('ExportedUAVModel',exportedSet);

Close Model

bdclose(modelName);
