Crossing the Borderline - From Formal to Semi-Formal Specifications

Being part of the systems' documentation state-based formal specifications can play a crucial role in the software development process. Hovv'ever, besides dense mathematical expressions, their semantical compactness and lack in visually appealing notations impede their use and comprehensibility among different stakeholders. One solution to this problem is to enrich the specification by a semi-formal view, in most cases diagrams with a sufficiently understood semantic meaning. However, as controland data-dependencies within declarative specifications are hard to detect, existing approaches only cover statics-bearing diagrams. As a way out this paper presents an approach for controland data dependency analysis within declai-ative formal specifications. Based on these dependencies, UML diagrams showing static and dynamic properties of the specification arc generated.
