| contents | As the complexity of safety-critical medical devices increases, so does the need for clear, verifiable, software requirements. This paper explores the use of Kapture, a formal modelling tool developed by D-RisQ, to translate an existing formal VDM model of a medical implant for treating focal epilepsy called CANDO. The work was undertaken without prior experience in formal methods. The paper assess Kapture's usability, the challenges of formal modelling, and the effectiveness of the translated model. The result is a model in Kapture which covers over 90% of the original VDM model, and produces matching traces of results. While several issues were encountered during design and implementation, mainly due to the initial learning curve, this paper demonstrates that complex systems can be effectively modelled in Kapture by inexperienced users and highlights some difficulties in translating VDM specifications to Kapture. |
