Functional testing includes assessing simulation behavior and comparing simulation data to expected results. You can assess simulation behavior by:
Using temporal and logical assessments in a test case.
verify statements and other operators
in a Test Assessment or Test Sequence
Using blocks from the Model Verification library.
You can assess simulation data by:
Using value or time tolerances when comparing simulation data to baseline data.
Using a custom criteria script to process simulation data.
For an overview of the different verification methods, see Assess Simulation and Compare Output Data.
