Generate Tests

Generate sets of tests to satisfy model and code coverage and custom testing criteria

Test generation produces sequences of input values for your models to satisfy testing criteria, such as model coverage. Simulink® Design Verifier™ extends existing model coverage information from requirements-based tests. It generates additional sequences of test inputs that meet the coverage objectives not satisfied during requirements-based testing. Use these test inputs to better understand missing requirements and to create a more complete test harness.

Test ConditionConstrain signal values in test cases
Test ObjectiveDefine custom objectives that signals must satisfy in test cases
DetectorDetect true duration on input and construct output true duration based on output type
ExtenderExtend true duration of input
ImpliesSpecify condition that produces a certain response
Within ImpliesVerify response occurs within desired duration
Verification SubsystemSpecify proof or test objectives without impacting simulation results or generated code
