Code Coverage

The Code Coverage dialog provides statistics about the executed code. Use this information together with the information from the Disassembly Window.

Code Coverage Dialog

The statistics are updated automatically whenever the program flow is stopped.

Update shows the latest statistics without stopping the program.
Clear resets the statistics to zero.
Module lists the individual functions included in the project.

Note

Code coverage is possible for most devices when using the µVision Simulator. When debugging on hardware, enable tracing as described in Configure Cortex-M Devices for Tracing.
Use debug command COVERAGE to output information in the Command window.
Expressions describes the debug commands syntax and offers additional examples.
For using fully qualified symbols refer to Fully Qualified Symbols.
