“…The guidelines are the result of our experience of designing and verifying a number of real industrial cases, developed under the control of various formal techniques . Moreover, the guidelines were applied to design and verify an industrial case developed at Philips Healthcare , and hence, the guidelines could provide an effective framework to design verifiable components.…”

SUMMARYDuring the last two decades, we modelled the behaviour of a large number of systems. We noted that different styles of modelling had quite an effect on the size of the state spaces of the modelled systems. The differences were so substantial that some specification styles led to far too many states to verify the correctness of the model, whereas with other styles, the number of states was so small that verification was a straightforward activity. In this article, we summarize our experience by providing seven specification guidelines to keep state spaces small. For each guideline, we provide an application, generally from the realm of traffic light controllers, for which we provide a 'bad' model with a large state space, and a 'good' model with a small state space. The good and bad models are both suitable for their purpose but are not behaviourally equivalent. For all guidelines, we discuss circumstances under which it is reasonable to apply the guidelines.

Abstract. This paper reports on experiences from an industrial project related to developing control components of an interventional X-ray system, using formal techniques supplied by the Analytical Software Design approach, of the company Verum. We illustrate how these formal techniques were tightly integrated with the standard development processes and the steps accomplished to obtain verifiable components using model checking. Finally, we show that applying these formal techniques could result in quality software and we provide supporting statistical data for this regard.
