System Composer
Design and analyze system and software architectures
System Composer™ enables the definition, analysis, and specification of architectures and compositions for model-based systems engineering and software design. With System Composer, you allocate requirements while refining an architecture model that can then be designed and simulated in Simulink®.
System Composer lets you create or import architecture models that describe a system in terms of components and interfaces. You can also populate an architecture model from the architectural elements of Simulink designs or C/C++ code. You can create custom live views of the model to study specific design or analysis concerns. With these architecture models you can analyze requirements, capture properties via stereotyping, perform trade studies, and produce specifications and ICDs.
Get Started:
Composition Hierarchies
Sketch hierarchical system and software decompositions of components using a familiar component, port, and connector modeling approach. Iteratively add more details to your design until you are ready for implementation in Simulink.
Interface Management
Specify and refine interfaces on ports to define the information exchanged between components. Verify interface compatibility between ports by checking units, types, and other characteristics. Manage interfaces in dictionaries to facilitate reuse across multiple models of a project.
Apply an interface to a port by creating a new interface or selecting an existing interface. Specify the type, dimensions, units, and structure of the data.
Architecture Import
Reuse your existing design artifacts and Interface Control Document (ICD) information by connecting external repositories and files to MATLAB® and using an API to import the information into System Composer.
Connect external repositories and files to MATLAB and use an API to import the information.
Creating and Linking Simulink Components
Create, link, and manage Simulink behavioral components and interfaces as part of your top-down architecture design.
Reusing Simulink Models
Create architectural models bottom-up from existing Simulink models. Extract a composition from an existing Simulink system model or synthesize one from a set of Simulink component models.
Creating Behavioral Specifications
Capture and simulate desired system behavior in Simulink and Stateflow® to refine and validate your requirements and architecture in System Composer.
Use Stateflow with MATLAB App Designer to create executable prototypes that are used to refine and validate requirements.
Requirements Allocation
Allocate requirements from external sources to architecture elements. Visualize and trace requirements from architectural elements, derive next-level requirements, and decompose architectures interactively.
Requirements Analysis
With Simulink Requirements™, you can perform requirements coverage analysis to assess the completeness of your architecture. Requirement changes resulting in suspect links are highlighted to support impact analysis.
Stereotypes
Add custom properties to architectural elements using stereotypes. Group and extend interrelated stereotypes in a profile that can be applied to an architecture.
Trade Studies Using MATLAB Analytics
Optimize architectures based on trade study results. Traverse architectures by hierarchy or connectivity, and perform roll-ups of parametric information. Create your own MATLAB analysis scripts to be applied on demand.
Directly access architecture data with MATLAB and use your own analysis scripts to perform trade studies, such as a roll-up to calculate the total mass of the system.
Architecture Reference
Reuse architecture component definitions by saving a component and its decomposition in a separate file and then referencing the component from other components in the architecture. Use the same mechanism to partition your overall design into separate model artifacts. You can define variants between multiple reference architectures for one component.
Create a reusable component that contains its interface and hierarchy that can be used to implement other components.
Architecture Projects
For large architectures, use projects to facilitate component reuse, modular team-based design, and the release of independent components. Projects support large-scale componentization by enabling you to reference other projects from a parent project.
Projects can be referenced by other projects supporting large scale componentization.
Architecture Views
Create customized views for specific design or analysis concerns that enable communication between multiple stakeholders. For example, you can create views that contain only the software, mechanical, or electrical elements. Through views, contextually edit design properties and link requirements that will be reflected throughout the model.
Spotlight Views
Generate a pre-configured view that shows the context of a component and its connectivity. Use it to examine which components and interfaces will be impacted by a change.
Model to Model Allocations
Establish directed relationships between elements of two architectural models representing different aspects of the system
Stereotype-Based Styling
Style components and connectors in the model based on stereotypes with custom colors and icons
Architecture Views
Create multiple persistent views for an architecture model, including with automation using visual filters, for different concerns
Hierarchy Diagrams
Represent any architecture view as a tree diagram showing the component hierarchy and properties
Requirements Linking
Link requirements to components and ports of an architecture model from any view (requires Simulink Requirements)
Interface Stereotypes
Apply stereotypes for custom metadata on interface objects
Linked Data Dictionaries
Define interface objects across multiple linked data dictionaries for separation of concerns
Interface Adaptor
Visually specify interface mapping between components with different but compatible interfaces
See release notes for details on any of these features and corresponding functions.
