Abstract: High level Petri nets have been extensively used for system modeling; however their strong expressive power cost their analyzability. Currently, there are no effective general formal analysis techniques for high level Petri nets. Fortunately, high level Petri nets are executable and as a result they can be tested. In recent years, some theoretical testing adequacy coverage measurements have been proposed. In this paper, we propose an approach to validate the above theoretical results through experiments using the simulation functionality of the model checker Spin.
