Author Architecture Models

Represent architectures using components, ports, and interfaces

Model the physical, functional, and logical architecture of a system. Create visual representations with components, ports, and connections. Components represent architectural systems or subsystems to be used in system design. You can decompose components to add detail and define hierarchical relationships, and you can reuse and reference components across composition models. Convert to architecture model and subsystem references to reuse architectural designs across components. Create variant components and implement multiple design alternatives or variants, chosen based on programmatic rules.

Specify information exchange between components with data interfaces, physical interfaces, and value types using the Interface Editor. A data interface defines the type, dimensions, units, and structure of the data contained within a port and exchanged between components. You can define interfaces locally that are saved with the model, or you can define interfaces in a System Composer™ interface data dictionary to be used across models.

Add and edit intrinsic or operational parameters for architectural design on components and architectures using the Parameter Editor. Promote parameters from components contained in the model to a top-level architecture.

Author edit-time checks for System Composer or define customizations using sl_refresh_customizations.
