What is atomic Subchart?

An atomic subchart is a graphical object that helps you to create independent subcomponents in a Stateflow® chart. Atomic subcharts are not supported in standalone Stateflow charts in MATLAB®. Atomic subcharts allow for: Reuse of the same state or subchart across multiple charts and models.

What is subchart in Stateflow?

A subchart is a graphical object that can contain anything that a top-level chart can, including other subcharts. A subchart, or a subcharted state, is a superstate of the states that it contains. You can nest subcharts to any level in your chart design.

Why Stateflow is used?

Stateflow is used to respond to instantaneous changes in dynamic changes. Real-world systems have to respond to both continuous and instantaneous changes. Use both Simulink and Stateflow so that you can use the right tool for the right job.

What is super transition in stateflow?

A supertransition is a transition between different levels in a chart. A supertransition can go between a state in a top-level chart and a substate in one of its sibling states, or between substates in different states of the chart.

What is Stateflow onramp?

Description. Stateflow® Onramp is a self-paced, interactive tutorial that helps you get started with Stateflow. It is included with a Stateflow license. After completing Stateflow Onramp, you will be able to use the Stateflow environment and build Stateflow charts based on real-world examples.

What Stateflow chart provides in Simulink?

Stateflow® provides a graphical language that includes state transition diagrams, flow charts, state transition tables, and truth tables. You can use Stateflow to describe how MATLAB® algorithms and Simulink® models react to input signals, events, and time-based conditions.

What is default transition in Stateflow?

A default transition specifies which exclusive (OR) state to enter when there is ambiguity among two or more neighboring exclusive (OR) states. A default transition has a destination but no source object.

What is parallel state in Stateflow?

A chart or state with parallel states has two or more states that can be active at the same time. A chart or state that contains parallel (AND) states is said to have parallel decomposition. Parallel (AND) states are displayed as dashed rectangles.

How do I create an atomic subchart?

You can create an atomic subchart by converting an existing subchart or by linking a chart from a library model. After creating the atomic subchart, update the mapping of variables by right-clicking the atomic subchart and selecting Subchart Mappings.

What is the difference between an atomic subchart and normal subchart?

An atomic subchart looks opaque and includes the label Atomic in the upper left corner. If you use a linked atomic subchart from a library, the label Link appears in the upper left corner. This example illustrates the difference between a normal subchart and an atomic subchart. In the Air Controller chart, PowerOff is a normal subchart.

What are the disadvantages of atomic subcharts?

Atomic subcharts do not support access to: Data at every level of the chart hierarchy. Event broadcasts outside the scope of the atomic subchart. Atomic subcharts do not support explicit specification of sample time. You can create an atomic subchart by converting an existing subchart or by linking a chart from a library model.
