Build an Architecture Model from Command Line

This example shows how to build an architecture model using the System Composer API.

Prepare Workspace

systemcomposer.profile.Profile.closeAll;

Build a Model

Add Components, Ports, and Connections

model = systemcomposer.createModel('mobileRobotAPI');
arch = model.Architecture;
components = addComponent(arch,{'Sensor','Planning','Motion'});
sensorPorts = addPort(components(1).Architecture,{'MotionData','SensorData'},{'in','out'});
planningPorts = addPort(components(2).Architecture,{'Command','SensorData','MotionCommand'},{'in','in','out'});
motionPorts = addPort(components(3).Architecture,{'MotionCommand','MotionData'},{'in','out'});
c_sensorData = connect(arch,components(1),components(2));
c_motionData = connect(arch,components(3),components(1));
c_motionCommand = connect(arch,components(2),components(3));

Add and Connect an Architecture Port

Add a port on the architecture. This is an architecture port.

archPort = addPort(arch,'Command','in');

The connect command requires a component port as argument. Obtain the component port and connect:

compPort = getPort(components(2),'Command');
c_Command = connect(archPort,compPort);

Save the model.

save(model)

Open the model

open_system(gcs);

Arrange the layout by pressıng Ctrl+Shift+A or using the following command.

Simulink.BlockDiagram.arrangeSystem('mobileRobotAPI'); 

Create and Apply Profile and Stereotypes

Profiles are xml files that can be applied to any model.

Create a Profile and Add Stereotypes

Create a profile.

profile = systemcomposer.createProfile('GeneralProfile');

Create a stereotype that applies to all element types:

elemSType = addStereotype(profile,'projectElement');

Create stereotypes for different types of components. These types are dictated by design needs and are at the discretion of the user:

pCompSType = addStereotype(profile,'physicalComponent','AppliesTo','Component');
sCompSType = addStereotype(profile,'softwareComponent','AppliesTo','Component');

Create a stereotype for connections:

sConnSType = addStereotype(profile,'standardConn','AppliesTo','Connector');

Add Properties

Add properties to stereotypes. You can use properties to capture metadata for model elements and analyze non-functional requirements. These properties are added to all elements to which the stereotype is applied, in any model that imports the profile.

addProperty(elemSType,'ID','Type','uint8');
addProperty(elemSType,'Description','Type','string');
addProperty(pCompSType,'Cost','Type','double','Units','USD');
addProperty(pCompSType,'Weight','Type','double','Units','g');
addProperty(sCompSType,'develCost','Type','double','Units','USD');
addProperty(sCompSType,'develTime','Type','double','Units','hour');
addProperty(sConnSType,'unitCost','Type','double','Units','USD');
addProperty(sConnSType,'unitWeight','Type','double','Units','g');
addProperty(sConnSType,'length','Type','double','Units','m');

Apply Profile to Model

Apply profile to the model:

applyProfile(model,'GeneralProfile');

Apply stereotypes to components. Some components are physical components, others are software components.

applyStereotype(components(2),'GeneralProfile.softwareComponent')
applyStereotype(components(1),'GeneralProfile.physicalComponent')
applyStereotype(components(3),'GeneralProfile.physicalComponent')

Apply the connector stereotype to all connections:

batchApplyStereotype(arch,'Connector','GeneralProfile.standardConn');

Apply the general element stereotype to all connectors and ports:

batchApplyStereotype(arch,'Component','GeneralProfile.projectElement');
batchApplyStereotype(arch,'Connector','GeneralProfile.projectElement');

Set properties for each component:

setProperty(components(1),'GeneralProfile.projectElement.ID','001');
setProperty(components(1),'GeneralProfile.projectElement.Description','''Central unit for all sensors''');
setProperty(components(1),'GeneralProfile.physicalComponent.Cost','200');
setProperty(components(1),'GeneralProfile.physicalComponent.Weight','450');
setProperty(components(2),'GeneralProfile.projectElement.ID','002');
setProperty(components(2),'GeneralProfile.projectElement.Description','''Planning computer''');
setProperty(components(2),'GeneralProfile.softwareComponent.develCost','20000');
setProperty(components(2),'GeneralProfile.softwareComponent.develTime','300');
setProperty(components(3),'GeneralProfile.projectElement.ID','003');
setProperty(components(3),'GeneralProfile.projectElement.Description','''Motor and motor controller''');
setProperty(components(3),'GeneralProfile.physicalComponent.Cost','4500');
setProperty(components(3),'GeneralProfile.physicalComponent.Weight','2500');

Set the properties of connections to be identical:

connections = [c_sensorData c_motionData c_motionCommand  c_Command];
for k = 1:length(connections)
    setProperty(connections(k),'GeneralProfile.standardConn.unitCost','0.2');
    setProperty(connections(k),'GeneralProfile.standardConn.unitWeight','100');
    setProperty(connections(k),'GeneralProfile.standardConn.length','0.3');
end

Create an Interface

Create a data dictionary and add an interface:

dictionary = systemcomposer.createDictionary('SensorInterfaces.sldd');
interface = addInterface(dictionary,'GPSInterface');

Link the interface to the model:

linkDictionary(model,'SensorInterfaces.sldd');

Identify the interface in the dictionary:

interface_GPS = getInterface(model.InterfaceDictionary,'GPSInterface');

Set the interface for the port:

setInterface(sensorPorts(2),interface_GPS);

Save Data Dictionary

Save the changes to the data dictionary.

dictionary.save(); 

Clean Up

Uncomment the following code and run to clean up the artifacts created by this example:

% bdclose('mobileRobotAPI');
% systemcomposer.profile.Profile.closeAll;
% delete('SensorInterfaces.sldd');
