Author System Behaviors

Associate architectures with Simulink®, Stateflow®, and Simscape™ and use sequence diagrams to describe system behavior

Define system behaviors in architecture models to determine the purpose of the system and to assess how to design the system. Use sequence diagrams integrated with System Composer™ to describe system behaviors as the interaction between components in a sequence of message exchanges.

Define component behaviors to implement system design.

  • Define component behavior by linking to a Simulink model or a Simulink subsystem.

  • Add state machine behavior in Stateflow to components.

  • Add physical behavior in Simscape to components.

Use parameters, specified as model arguments, to specify instance-specific values on components. Each component linked to the same referenced model or architecture can specify independent values for a parameter.
