Stateflow User's Guide

Monitoring Stateflow Test Points

A Stateflow test point is a signal that Stateflow guarantees to be observable, for example, by a Floating Scope block, during a simulation. Stateflow allows you to designate a data or a state in a Stateflow diagram as a test point. While all Stateflow states can be test points, only Stateflow data of local scope qualify. They can be scalar, one-dimensional, or two-dimensional in size, and of any data type except type ml. Like states, test point data must also be a descendant of a Stateflow chart.

You implicitly declare all Stateflow data of local scope and all states as test points if the Enable debugging/animation code option is selected for the Stateflow simulation target. If this option is not set, you can specify individual local data or states as test points by setting their TestPoint property in the Stateflow API or through the Model Explorer (see Setting Test Points for Stateflow States and Local Data with Model Explorer).

You can monitor individual Stateflow test points with a floating scope during model simulation. You can also log test point values into MATLAB workspace objects. Use the following topics to learn how to set test points and display the values of Stateflow test points while you are simulating a model.

• Setting Test Points for Stateflow States and Local Data with Model Explorer -- Through Model Explorer, set test points for states and local data for logging and monitoring.
• Logging Data Values and State Activity -- During simulation, log data values and state activity values into MATLAB objects for reporting and plotting.
• Using a Floating Scope to Monitor Data Values and State Activity -- Use a Floating Scope block to monitor Stateflow data values continuously during simulation.
