Analyze Coverage and View Results

View coverage highlighting in models, generate coverage reports, trace results to tests and requirements

You can use Simulink® Coverage™ to evaluate coverage data to find gaps in your testing or issues in your design. You can compare the coverage results of normal mode simulations with the generated code results from software-in-the-loop, processor-in-the-loop, or hardware-in-the-loop simulations.

Coverage reports and model highlighting help you to understand which parts of your design are sufficiently exercised by your test cases. For aggregated test results, you can also view how each corresponding test contributes to the coverage results.

Top-Level Model Coverage Report

Learn about the sections of a model coverage report the software creates for the top-level model.

View Coverage Results in Simulink Canvas

Highlight model elements in the Simulink Canvas to view coverage results.

Types of Coverage Reports

Simulink Coverage can create one or more model coverage reports after a simulation.

Trace Coverage Results to Associated Test Cases

View system test coverage achieved from unit tests in the Aggregated Tests section of the coverage report.

Trace Coverage Results to Requirements

View requirements traceability in Simulink Coverage reports using Simulink Test™.

Assess Coverage Results from Requirements-Based Tests

Assess extent to which requirements-based tests exercise the corresponding design.
