WebIf the bin designates a set of values, the count is incremented every time the coverage point matches one of the values in the set. If the bin designates a sequence of value transitions, the count is incremented every time the coverage point matches the entire sequence of value transitions. Bins can be created implicitly or explicitly. Implicit ... WebFunctional coverage is user-defined, mapping all functionality defined in the test plan to be tested to a cover point. Whenever the functionality is hit during simulation, the functional coverage point is automatically updated. A functional coverage report can be generated summarizing how many coverage points were hit, metrics that can be used how many people have been to orbit
