Link to architectural definition or Simulink behavior
Use a Reference Component block to link an architectural definition of a System Composer™ component, an architectural definition of an AUTOSAR component, or a Simulink® behavior.
Add ports to the block to connect to other components. Define an interface for the ports, add properties associated with the component using stereotypes, and define parameters.
To add or connect System Composer components:
Add an architecture Reference Component block from the Modeling tab or the palette. You can also click and drag a box on the canvas, then select the Reference Component block.
Attach a referenced model to the component by selecting
<Enter Model Name>.
Add and edit ports on a Reference Component block. Click the edge of the block to add a port, then use the Property Inspector to rename the port.
To import your shared data dictionary from your System Composer architecture model, in the Model Explorer for your referenced model, under Model Properties, on the External Data tab, click Browse. Use the Interface Editor to assign interfaces to the ports of your referenced model and edit interface definitions.
Click and drag any port to create a connection. Connect to another component. You can also create a new component to complete the connection.
To connect Reference Component blocks to architecture or composition model root ports, drag from the component ports to the containing model boundary. When you release the connection, a root port is created at the boundary.
To manage Reference Component block contents:
When you create a Reference Component block, you have the option to right-click the component and select
Block Parameters. From here, you can specify your reference model or subsystem name, if it already exists. The reference model or subsystem can be a System Composer architecture, AUTOSAR architecture, or a Simulink model or subsystem.
To add or remove stereotypes from Reference Component blocks, first import the profile into the referenced model or subsystem using the Profile Editor.
To break the reference link for a Reference Component block, you have the option to right-click and select Inline Model, which removes the contents of the architecture model referenced by the specified component and breaks the link to the reference model. The Reference Component block becomes a regular Component block.
With a regular Component block, you can right-click the block and convert it to a reference component.
To save the contents of the component as an architecture model or subsystem that can be referenced in multiple places and kept in sync, select Create Architecture > Architecture. The component becomes a reference component that links to the referenced architecture model or subsystem.
To type ports on architecture subsystems with interfaces, you must link an external interface data dictionary. Architecture subsystems do not contain a model workspace. For more information, see Manage Interfaces with Data Dictionaries.
To save the contents of the component as software architecture model, select Create Architecture > Software Architecture.
Create Architectureand then select
Software Architecture. For more information, see Create Software Architecture from Architecture.
To save the contents of the component an AUTOSAR architecture model, select Create Architecture > AUTOSAR Architecture. For more information, see Create AUTOSAR Architecture from Component.
To create a new Simulink reference model or subsystem and link to it, select Create Behavior > Simulink Behavior. For more information, see Implement Component Behavior Using Simulink.
To link to a known model or subsystem, which can be a System Composer architecture model, a Simulink model, or an AUTOSAR architecture model, select Link to Model.
Components with physical ports cannot be saved as architecture models, model references, software architectures, or Stateflow® chart behaviors. Components with physical ports can only be saved as subsystem references or as subsystem component behaviors.
Source — Input connection from another component
If you connect to a source component, the interfaces on the ports are shared.
Destination — Output connection to another component
If you connect to a destination component, the interfaces on the ports are shared.
Physical — Physical connection to another component
If you connect to another component, the physical interfaces on the ports are shared.
A System Composer architecture represents a system of components and how they interface with each other structurally and behaviorally.
Different types of architectures describe different aspects of systems. You can use views to visualize a subset of components in an architecture. You can define parameters on the architecture level using the Parameter Editor.
A System Composer model is the file that contains architectural information, including components, ports, connectors, interfaces, and behaviors.
Perform operations on a model:
A System Composer model is stored as an SLX file.
|Create Architecture Model with Interfaces and Requirement Links
A component is a nontrivial, nearly independent, and replaceable part of a system that fulfills a clear function in the context of an architecture. A component defines an architectural element, such as a function, a system, hardware, software, or other conceptual entity. A component can also be a subsystem or subfunction.
Represented as a block, a component is a part of an architecture model that can be separated into reusable artifacts. Transfer information between components with:
A port is a node on a component or architecture that represents a point of interaction with its environment. A port permits the flow of information to and from other components or systems.
These are different types of ports:
Connectors are lines that provide connections between ports. Connectors describe how information flows between components or architectures.
A connector allows two components to interact without defining the nature of the interaction. Set an interface on a port to define how the components interact.
A physical subsystem is a Simulink subsystem with Simscape™ connections.
A physical subsystem with Simscape connections uses a physical network approach suited for simulating systems with real physical components and represents a mathematical model.
|Implement Component Behavior Using Simscape
A physical port represents a Simscape physical modeling connector port called a Connection Port (Simscape).
Use physical ports to connect components in an architecture model or to enable physical systems in a Simulink subsystem.
|Define Physical Ports on Component
A physical connector can represent a nondirectional conserving connection of a specific physical domain. Connectors can also represent physical signals.
Use physical connectors to connect physical components that represent features of a system to simulate mathematically.
|Architecture Model with Simscape Behavior for a DC Motor
A physical interface defines the kind of
information that flows through a physical port. The same interface can be assigned to multiple
ports. A physical interface is a composite interface equivalent to a
Use a physical interface to bundle physical elements to describe a physical model using at least one physical domain.
|Specify Physical Interfaces on Ports
A physical element describes the
decomposition of a physical interface. A physical element is equivalent to a
|Describe Component Behavior Using Simscape
A reference component is a component whose definition is a separate architecture model, Simulink behavior model, or Simulink subsystem behavior. A reference component represents a logical hierarchy of other compositions.
You can reuse compositions in the model using reference components. There are three types of reference components:
A parameter is an instance-specific value of a value type.
Parameters are available for inlined architectures and components. Parameters are also available for components linked to model references or architecture references that specify model arguments. You can specify independent values for a parameter on each component.
A subsystem component is a Simulink subsystem that is part of the parent System Composer architecture model.
Add Simulink subsystem behavior to a component to author a subsystem component in System Composer. You cannot synchronize and reuse subsystem components as Reference Component blocks because the component is part of the parent model.
A state chart diagram demonstrates the state-dependent behavior of a component throughout its state lifecycle and the events that can trigger a transition between states.
Add Stateflow chart behavior to describe a component using state machines. You cannot synchronize and reuse Stateflow chart behaviors as Reference Component blocks because the component is part of the parent model.
