Signal Logging and Test Point Monitoring

Track data values and state activity

Log local data, output data, and state self-activity by using signal logging. Monitor and access data from your Stateflow^® chart or from the MATLAB^® workspace.

Tools

Simulation Data Inspector

Inspect and compare data and simulation results to validate and iterate model designs

Objects

`Stateflow.SimulationData.Data`	Data values during simulation
`Stateflow.SimulationData.State`	State activity during simulation

Topics

Log Simulation Output for States and Data
Enable signal logging, configure states and data, and access the simulation output.
View State Activity by Using the Simulation Data Inspector
Monitor active state data through the Simulation Data Inspector.
View Stateflow States in the Logic Analyzer
Monitor Stateflow states using the Logic Analyzer app.
Log String Data to the Simulation Data Inspector
View text strings in the Simulation Data Inspector and in the MATLAB workspace.
Log Data in Library Charts
Override logging properties in chart instances linked from a library.

Featured Examples

Monitor Test Points in Stateflow Charts

Specify data or states as test points that you can plot using a Floating Scope and Scope Viewer (Simulink) block during simulation. You can designate states or data with these properties as test points:
