Configure AUTOSAR Architecture Model Programmatically

An AUTOSAR architecture model provides resources and a canvas for developing AUTOSAR composition and component models. You develop the software architecture by using graphical user interfaces, equivalent architecture modeling functions, or both. AUTOSAR Blockset provides functions for these architecture related tasks.

This example script:

  1. Creates and opens an AUTOSAR architecture model.

  2. Adds a composition and components.

  3. Adds architecture, composition, and component ports.

  4. Connects architecture, composition, and component ports.

  5. Creates and links Simulink implementation models for components.

  6. Arranges architecture model layout based on heuristics.

  7. Sets component and port properties.

  8. Removes a component.

  9. Searches for elements at different levels of the architecture model hierarchy.

  10. Lists property values for composition ports.

To run the script, copy commands from the MATLAB® script listing below to the MATLAB command window.

Alternatively, you can copy the script file configAutosarArchModel.m to your working folder and run the file. To copy the script to your working folder, enter this MATLAB command:

copyfile(fullfile(matlabroot,'help/toolbox/autosar/examples/configAutosarArchModel.m'),'.')
% configAutosarArchModel.m
%
% Configure AUTOSAR architecture model.
% This script creates models Controller1.slx and Actuator.slx.
% To rerun the script, remove the models from the working folder.

% Create and open AUTOSAR architecture model
modelName = 'myArchModel';
archModel = autosar.arch.createModel(modelName);

% Add a composition
composition = addComposition(archModel,'Sensors');

% Add 2 components inside Sensors composition
names = {'PedalSnsr','ThrottleSnsr'};
sensorSWCs = addComponent(composition,names,'Kind','SensorActuator');
layout(composition);  % Auto-arrange composition layout

% Add components at architecture model top level (call layout to arrange blocks)
addComponent(archModel,'Controller1');
actuator = addComponent(archModel,'Actuator');
set(actuator,'Kind','SensorActuator');

% Add architecture ports
addPort(archModel,'Receiver',{'TPS_Hw','APP_Hw'});
addPort(archModel,'Sender','ThrCmd_Hw');

% Add composition ports
addPort(composition,'Receiver',{'TPS_Hw','APP_Hw'});
addPort(composition,'Sender',{'TPS_Perc','APP_Perc'});

% Add component ports
controller = find(archModel,'Component','Name','Controller1');
addPort(controller,'Receiver',{'TPS_Perc','APP_Perc'});
addPort(controller,'Sender','ThrCmd_Perc');
addPort(actuator,'Receiver','ThrCmd_Perc');
addPort(actuator,'Sender','ThrCmd_Hw');

% At top level, connect composition and components based on matching port names
connect(archModel,composition,controller);
connect(archModel,controller,actuator);

% Connect specified arch root ports to specified composition and component ports
connect(archModel,archModel.Ports(1),composition.Ports(1));
% Use find to construct port specifications
connect(archModel,...
    find(archModel,'Port','Name','APP_Hw'),...
    find(composition,'Port','Name','APP_Hw'));
connect(archModel,actuator.Ports(2),archModel.Ports(3));
% ALTERNATIVELY, connect architecture root ports based on matching port names
% connect(archModel,[],composition);
% connect(archModel,actuator,[]);

% Create implementation models for controller and actuator components
createModel(controller);
createModel(actuator);

% Link implementation model to PedalSnsr component inside Sensors
pedalSnsr = find(composition,'Component','Name','PedalSnsr');
% Add path to implementation model
addpath(fullfile(matlabroot,'/examples/autosarblockset/main'));
linkToModel(pedalSnsr,'autosar_tpc_pedal_sensor');

% Set properties
set(composition.Ports(1),'Name','NewPortName1'); % Names for Sensors composition ports
set(composition.Ports(3),'Name','NewPortName2');
set(find(controller,'Port','Name','TPS_Perc'),...
    'Name','NewPortName3');     % Port name for Controller1 component & implementation
set(controller,'Kind','ServiceProxy');  % Component type for Controller1 component
set(controller,'Name','Instance1');     % Name for Controller1 component

% Destroy component ThrottleSensor inside Sensors
throttleSnsr = find(composition,'Component','Name','ThrottleSnsr');

% Find components in all hierarchy

% Find ports for composition block only
