Export architecture model and dependencies to previous release of System Composer

Since R2019b



    systemcomposer.exportToVersion(modelName,dirName,version) exports an architecture model with name modelName and its dependencies to the version of System Composer™ given by version. The exported artifacts are created in a directory specified by dirName.

    TermDefinitionApplicationMore Information

    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.


    The root is at the top of an architecture hierarchy. A root architecture has a boundary defined by its architecture ports surrounding 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.

    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.

    • Attach interface data dictionaries.

    • Generate instances from model architecture.

    A System Composer model is stored as an SLX file.

    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:

    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


    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.
