Test postcondition items for automated analysis and test generation

In one embodiment, a design is verified by creating a graphical model with a graphical modeling tool executing on a computing device. The graphical model may include a plurality of model elements. A postcondition element is coupled to a selected model element of the plurality of model elements. The postcondition element is associated with a desired result. The graphical model is employed to generate an executable form of the design. The executable form of the design and an indication of the desired result are provided to a verification tool, to instruct the verification tool to implement one or more verification scenarios.
