System Composer Concepts

System Composer™ combines concepts from systems engineering with concepts from Simulink^®. This page defines these concepts and their respective applications to help you understand how these domains overlap in System Composer.

Use this page to learn about System Composer concepts and how they apply to systems engineering design. Each section defines a concept, explains how the concept is used in System Composer, then links to more information in the documentation. Based on your architectural modeling goal, review the corresponding section to learn more about key concepts associated with that goal.

Author Models to Describe Structure of System and Software Architectures

An architecture model in System Composer consists of the common Simulink constructions: components, ports, and connectors. An architecture represents a system of components.

Term	Definition	Application	More Information
architecture	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.	Compose Architectures Visually Author Parameters in System Composer Using Parameter Editor
root	A root is at the top of an architecture hierarchy. A root architecture has a boundary defined by its architecture ports that surround the system of interest.	The root architecture has a system boundary surrounding your architecture model. You can add architecture ports that define interfaces across the boundary.	Compose Architectures Visually
model	A System Composer model is the file that contains architectural information, such as components, ports, connectors, interfaces, and behaviors.	Perform operations on a model: Extract root-level architecture. Apply profiles. Link interface data dictionaries. Generate instances from model architecture. A System Composer model is stored as an SLX file.	Create Architecture Model with Interfaces and Requirement Links
component	A component is a 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, another 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: Port interfaces using the Interface Editor Parameters using the Parameter Editor	Compose Architectures Visually
port	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.	Component ports are interaction points on the component to other components. Architecture ports are ports on the boundary of the system, whether the boundary is within a component or the overall architecture model. The root architecture has a boundary defined by its ports.	Compose Architectures Visually
connector	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.	Compose Architectures Visually

Represent Design Alternatives Using Variant Components

Create variant components and implement multiple design alternatives or variants, chosen based on programmatic rules. Add variant choices to a component to make a variant component. The active choice represents the original component.

Term	Definition	Application	More Information
variant	A variant is one of many structural or behavioral choices in a variant component.	Use variants to quickly swap different architectural designs for a component while performing analysis.	Create Variants
variant control	A variant control is a string that controls the active variant choice.	Set the variant control programmatically to control which variant is active.	Set Variant Control Condition

Describe Port Specifications Using Interfaces

Define interfaces to represent the kind of information that flows through a port. Assign interfaces to ports using the Interface Editor in Dictionary View. Use an Adapter block to reconcile differences between interfaces on a connector between ports.

Manage owned interfaces local to a port using the Interface Editor in Port Interface View.

Term	Definition	Application	More Information
interface data dictionary	An interface data dictionary is a consolidated list of interfaces and value types in an architecture and where you use them in the architecture.	You can save local interfaces on a System Composer model in an interface data dictionary using the Interface Editor. You can reuse data dictionaries between models that need to use a given set of interfaces, elements, and value types. Data dictionaries that you link to models are stored in separate SLDD files.	Manage Interfaces with Data Dictionaries Reference Data Dictionaries
data interface	A data interface defines the kind of information that flows through a port. The same interface can be assigned to multiple ports. A data interface can be composite, meaning that it can include data elements that describe the properties of an interface signal.	Data interfaces represent the information that is shared through a connector and enters or exits a component through a port. Use the Interface Editor to create and manage data interfaces and data elements and store them in an interface data dictionary for reuse between models.	Create Architecture Model with Interfaces and Requirement Links Define Port Interfaces Between Components
data element	A data element describes a portion of an interface, such as a communication message, a calculated or measured parameter, or other decomposition of that interface.	Data interfaces are decomposed into data elements: Pins or wires in a connector or harness. Messages transmitted across a bus. Data structures shared between components.	Create Interfaces Assign Interfaces to Ports
value type	A value type can be used as a port interface to define the atomic piece of data that flows through that port and has a top-level type, dimension, unit, complexity, minimum, maximum, and description.	You can also assign the type of data elements in data interfaces to value types. Add value types to data dictionaries using the Interface Editor so that you can reuse the value types as interfaces or data elements.	Create Value Types as Interfaces
owned interface	An owned interface is an interface that is local to a specific port and not shared in a data dictionary or the model dictionary.	Create an owned interface to represent a value type or data interface that is local to a port.	Define Owned Interfaces Local to Ports
adapter	An adapter connects two components with incompatible port interfaces by mapping between the two interfaces. An adapter can act as a unit delay, rate transition, or merge. You can also use an adapter for bus creation. Use the Adapter block to implement an adapter.	With an adapter, you can perform functions on the Interface Adapter dialog box: Create and edit mappings between input and output interfaces. Apply an interface conversion UnitDelay to break an algebraic loop. Apply an interface conversion RateTransition to reconcile different sample time rates for reference models. Apply an interface conversion Merge to merge two or more message or signal lines. When output interfaces are undefined, you can use input interfaces in bus creation mode to author owned output interfaces.	Interface Adapter Adapter

To enhance traceability of requirements, link system, functional, customer, performance, or design requirements to components and ports. Link requirements to each other to represent derived or allocated requirements. Manage requirements from the Requirements Perspective on an architecture model or through custom views. Assign test cases to requirements using the Simulink Test Manager (Simulink Test) for verification and validation.	Link and Trace Requirements Establish Traceability Between Architectures and Requirements
requirement set	A requirement set is a collection of requirements. You can structure the requirements hierarchically and link them to components or ports.	Use the Requirements Editor (Requirements Toolbox) to edit and refine requirements in a requirement set. Requirement sets are stored in SLREQX files. You can create a new requirement set and author requirements using Requirements Toolbox, or import requirements from supported third-party tools.	Allocate and Trace Requirements from Design to Verification Manage Requirements

Scope Complex Architectures into Simpler Diagrams by Creating Filtered Views

Apply a view filter to generate an element group of components for the view in the Architecture Views Gallery.

Term	Definition	Application	More Information
view	A view shows a customizable subset of elements in a model. Views can be filtered based on stereotypes or names of components, ports, and interfaces, along with the name, type, or units of an interface element. Create views by adding elements manually. Views create a simplified way to work with complex architectures by focusing on certain parts of the architectural design.	You can use different types of views to represent the system. Switch between a component diagram, component hierarchy, or architecture hierarchy. For software architectures, you can switch to a class diagram view. A viewpoint represents a stakeholder perspective that specifies the contents of the view.	Create Custom Views Using Architecture Views Gallery Modeling System Architecture of Keyless Entry System

 && instance.hasValue('RobotProfile.ElectricalComponent.Power')
    sysComponent_power = 0;
    for child = instance.Components
        if child.hasValue('RobotProfile.ElectricalComponent.Power')
           comp_power = child.getValue('RobotProfile.ElectricalComponent.Power');
           sysComponent_power = sysComponent_power + comp_power;
