On the integration of formal methods: Events and scenarios (1999) [3 citations — 2 self]
|
Abstract:
This paper presents an approach for integrating formal methods tools. Given a specific application, for each tool involved, a formal specification has to be developed. As different tools are used for different purposes, the various specifications do not necessarily contain the same information. The proposed approach is based on dividing each specification in two parts, LOG and ENV. According to the purposes for which the tools will be used, the key idea is to first identify the information that is likely to change. This information is then put in the LOG part (for logic), which is required to be as independent of the formalism/tool as possible. Ideally, it is equivalent in all specifications such that the information in LOG can easily be modified in all system artifacts. It is demonstrated how this approach can be used to apply PVS and VDM on one aspect of a substantial example: the scenario of an access control. We define a scenario as all possible sequences of events. The paper contains a general presentation of the features of the access control. Parts of the VDM specification covering the entire functionality are shown. It is worth noticing that the proposed approach differs from earlier work [1] in a sense that there exists a mapping only between the LOG parts of
