What Is System Composer?

System Composer™ is a Model-Based Systems Engineering tool for system and software architecture design that allows you to decompose complex systems or a system-of-systems into smaller, more manageable pieces. This easy-to-use tool bridges the gap between high-level requirements and low-level algorithm and simulation workflows, allowing for scalable specification and analysis of system and software architectures.

The tool lets you author and edit architectures, link requirements to architecture and test cases, and define custom properties of architectural elements. With System Composer, you can generate new views of the model to gain insight into functional flows, component dependencies, and more. You can also edit those views directly. You can define software architectures from built-in templates that are generic, or specific like AUTOSAR Classic and Adaptive. You can even model the behavior using various formalisms such as block diagrams, state charts, and sequence diagrams. Another feature of System Composer is the ability to allocate or establish relationships between elements of different architecture models, which may represent different abstractions of a system, such as functional decomposition and logical or physical architectures. And of course, you can seamlessly integrate with Simulink^®, FMUs, Legacy Code, and more for traceability and continuity from MBSE concepts through Model-Based Design and verification.
