System Composer

Design and analyze system and software architectures

System Composer™ enables the specification and analysis of architectures for model-based systems engineering and software architecture modeling. With System Composer, you allocate requirements while refining an architecture model that can then be designed and simulated in Simulink^®.

Architecture models consisting of components and interfaces can be authored directly, imported from other tools, or populated from the architectural elements of Simulink designs. You can describe your system using multiple architecture models and establish direct relationships between them via model-to-model allocations. Behaviors can be captured and simulated in sequence diagrams, state charts, or Simulink models. You can define and simulate the execution order of component functions and generate code from your software and AUTOSAR architecture models (with Simulink and Embedded Coder^®, including AUTOSAR Blockset for AUTOSAR workflows).

To investigate specific design or analysis concerns, you can create custom live views of the model. Architecture models can be used to analyze requirements, capture properties via stereotyping, perform trade studies, and produce specifications and interface control documents (ICDs).

Design and analyze system and software architectures using System Composer.

Architecture Authoring

Create and elaborate specifications of architectures, compositions, and interfaces for model-based systems engineering and software.

Documentation | Examples

Requirements Allocation and Traceability

Associate architecture model elements with requirements. Iteratively decompose architectures while deriving additional requirements to create specifications.

What Is Requirements Toolbox? (2:25)

Documentation | Examples

Extend architecture with domain-specific design data.

Profiles and Analysis

Add custom properties to architectural elements to extend your architecture with domain-specific design data and apply MATLAB analytics to perform trade studies.

Documentation | Examples

Live Model Views

Produce model views for specific design or analysis concerns and easily visualize them using different diagram types.

Documentation | Examples

Architectural Allocation

Establish directed relationships between elements of two architecture models representing different aspects of the system such as functional, software, or physical architectures.

Documentation | Examples

Behavioral Modeling

Describe component and system-level behavior using various formalisms such as block diagrams, state charts, and sequence diagrams.

Documentation | Examples

Software/AUTOSAR Architectures

Define the execution order of functions, simulate the design at the architecture level, and generate and deploy code to your embedded system.

Documentation | Examples

Simulink Integration

Implement your architectural components in Simulink with consistent interfaces and traceability throughout Model-Based Design.

Documentation | Examples

Architecture Import and Export

Import an architectural model or ARXML (AUTOSAR XML) that was created in a third-party database or architecture modeling tool, edit it, and export it back with changes.
