Build Architecture Models Programmatically

Open Live Script

Build an architecture model programmatically using System Composer™.

To build a model, add a data dictionary with data interfaces, data elements, a value type, and a physical interface, then add components, ports, and connections. Create a profile with stereotypes and properties and then apply those stereotypes to model elements. Assign an owned interface to a port. After the model is built, you can create custom views to focus on specific considerations. You can also query the model to collect different model elements according to criteria you specify.

Add Components, Ports, Connections, and Interfaces

Create a model and extract its architecture.

model = systemcomposer.createModel("mobileRobotAPI");
arch = model.Architecture;

Create an interface data dictionary and add a data interface. Add a data element to the data interface. Add a value type to the interface data dictionary. Assign the type of the data element to the value type. Add a physical interface and physical element with a physical domain type. Link the data dictionary to the model.

dictionary = systemcomposer.createDictionary("SensorInterfaces.sldd");
interface = dictionary.addInterface("GPSInterface");
element = interface.addElement("SignalStrength");
valueType = dictionary.addValueType("SignalStrengthType",Units="dB", ...
    Description="GPS Signal Strength");
element.setType(valueType);
physicalInterface = dictionary.addPhysicalInterface("PhysicalInterface");
physicalElement = addElement(physicalInterface,"ElectricalElement", ...
    Type="electrical.electrical");
linkDictionary(model,"SensorInterfaces.sldd");

Save the changes to the interface data dictionary.

dictionary.save

Save the model.

model.save

Open the model.

systemcomposer.openModel("mobileRobotAPI");

View the interfaces in the Interface Editor.

Interface Editor with new data interfaces, data elements, value type, and physical interface

Add components, ports, and connections. Set the physical interface to the physical ports, which you connect later.

componentSensor = addComponent(arch,"Sensor");
sensorPorts = addPort(componentSensor.Architecture,{'MotionData','SensorPower'}, ...
    {'in','physical'});
sensorPorts(2).setInterface(physicalInterface)

componentPlanning = addComponent(arch,"Planning");
planningPorts = addPort(componentPlanning.Architecture, ...
    {'Command','SensorPower1','MotionCommand'}, ...
    {'in','physical','out'});
planningPorts(2).setInterface(physicalInterface)

componentMotion = addComponent(arch,"Motion");
motionPorts = addPort(componentMotion.Architecture,{'MotionCommand','MotionData'}, ...
    {'in','out'});

Create an owned interface on the MotionData port. Add an owned data element under the owned data interface. Assign the data element Rotation to a value type with units set to degrees.

ownedInterface = motionPorts(2).createInterface("DataInterface");
ownedElement = ownedInterface.addElement("Rotation");
subInterface = ownedElement.createOwnedType(Units="degrees");

View the interfaces in the Interface Editor. Select the MotionData port on the Motion component. In the Interface Editor, switch from Dictionary View to Port Interface View.

Port interface view in the Interface Editor with the MotionData port and its elements

Connect components with an interface rule and the default name rule. The interface rule connects ports on components that share the same interface. By default, the name rule connects ports on components that share the same name.

c_sensorData = connect(arch,componentSensor,componentPlanning,Rule="interface");
c_motionData = connect(arch,componentMotion,componentSensor);
c_motionCommand = connect(arch,componentPlanning,componentMotion);

Add and Connect Architecture Port

Add an architecture port on the architecture.

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

The connect command requires a component port as an argument. Obtain the component port, then connect.

compPort = getPort(componentPlanning,"Command");
c_Command = connect(archPort,compPort);

Save the model.

model.save

Create and Apply Profile with Stereotypes

Profiles are XML files that you can apply to any model. You can add stereotypes with properties to profiles and then populate the properties with specific values in the Profile Editor. Along with the built-in analysis capabilities of System Composer, stereotypes help you optimize your system for performance, cost, and reliability.

Create 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. You select these types according to your design needs.

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 the stereotypes. You can use properties to capture metadata for model elements and analyze nonfunctional 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");

Save Profile

profile.save;

Apply Profile to Model

Apply the profile to the model.

applyProfile(model,"GeneralProfile");

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

applyStereotype(componentPlanning,"GeneralProfile.softwareComponent")
applyStereotype(componentSensor,"GeneralProfile.physicalComponent")
applyStereotype(componentMotion,"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(componentSensor,'GeneralProfile.projectElement.ID','001');
setProperty(componentSensor,'GeneralProfile.projectElement.Description', ...
    'Central unit for all sensors');
setProperty(componentSensor,'GeneralProfile.physicalComponent.Cost','200');
setProperty(componentSensor,'GeneralProfile.physicalComponent.Weight','450');
setProperty(componentPlanning,'GeneralProfile.projectElement.ID','002');
setProperty(componentPlanning,'GeneralProfile.projectElement.Description', ...
    'Planning computer');
setProperty(componentPlanning,'GeneralProfile.softwareComponent.develCost','20000');
setProperty(componentPlanning,'GeneralProfile.softwareComponent.develTime','300');
setProperty(componentMotion,'GeneralProfile.projectElement.ID','003');
setProperty(componentMotion,'GeneralProfile.projectElement.Description', ...
    'Motor and motor controller');
setProperty(componentMotion,'GeneralProfile.physicalComponent.Cost','4500');
setProperty(componentMotion,'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

Add Hierarchy

Add two components named Controller and Scope inside the Motion component. Define the ports. Connect the components to the architecture and to each other, applying a connector stereotype. Hierarchy in an architecture diagram creates an additional level of detail that specifies how components behave internally.

motionArch = componentMotion.Architecture;

motionController = motionArch.addComponent('Controller');
controllerPorts = addPort(motionController.Architecture,{'controlIn','controlOut'}, ...
    {'in','out'});
controllerCompPortIn = motionController.getPort('controlIn');
controllerCompPortOut = motionController.getPort('controlOut');

motionScope = motionArch.addComponent('Scope');
scopePorts = addPort(motionScope.Architecture,{'scopeIn','scopeOut'},{'in','out'});
scopeCompPortIn = motionScope.getPort('scopeIn');
scopeCompPortOut = motionScope.getPort('scopeOut');

c_planningController = connect(motionPorts(1),controllerCompPortIn);

For output port connections, you can specify the destination data element.

c_planningScope = connect(scopeCompPortOut,motionPorts(2),DestinationElement="Rotation");
c_planningConnect = connect(controllerCompPortOut,scopeCompPortIn, ...
    "GeneralProfile.standardConn");

Save the model.

model.save

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

Create Model Reference

Model references can help you organize large models hierarchically and define architectures or behaviors once that you can then reuse. When a component references another model, any existing ports on the component are removed, and ports that exist on the referenced model will appear on the component.

Create a new System Composer model. Convert the Controller component into a reference component to reference the new model. To add ports on the Controller component, you must update the referenced model mobileMotion.

referenceModel = systemcomposer.createModel("mobileMotion");
referenceArch = referenceModel.Architecture;
newComponents = addComponent(referenceArch,"Gyroscope");
referenceModel.save

linkToModel(motionController,"mobileMotion");

Controller component linked to the referenced model mobileMotion

Save the models.

referenceModel.save
model.save

Make Variant Component

You can convert the Planning component to a variant component using the makeVariant function. The original component is embedded within a variant component as one of the available variant choices. You can design other variant choices within the variant component and toggle the active choice. Variant components allow you to choose behavioral designs programmatically in an architecture model to perform trade studies and analysis.

[variantComp,choice1] = makeVariant(componentMotion);

Add a variant choice named MotionAlt. The second argument defines the name, and the third argument defines the label. The label identifies the choice. The active choice is controlled by the label.

choice2 = addChoice(variantComp,{'MotionAlt'},{'MotionAlt'});

Create the necessary ports on MotionAlt.

motionAltPorts = addPort(choice2.Architecture,{'MotionCommand','MotionData'},{'in','out'});

Make MotionAlt the active variant.

setActiveChoice(variantComp,"MotionAlt")

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