The 20th Overture Workshop is the latest in a series of workshops around the Vienna Development Method (VDM), the open-source project Overture, and related tools and formalisms. VDM is one of the best established formal methods for systems development. A lively community of researchers and practitioners in academia and industry has grown around the modelling languages (VDM-SL, VDM++, VDM-RT) and tools (including VDMTools, Overture, INTO-CPS, ViennaTalk, VDMJ and VDM VSCode). Together, these provide a platform for work on modelling and analysis technology that includes IDEs, static and dynamic analysis, test generation, execution support, and model checking.

Previous workshops have been invaluable in encouraging both new and established members of the community in their work, and helping to determine priorities and future directions. Proceedings of former workshops are available at https://www.overturetool.org/.

Important Dates

25 April 2022: Submission of abstracts of papers

02 May 2022: Submission deadline for papers

15 June 2022: Notification to authors

24 June 2022: Final version of papers due

05 July 2022: Workshop


Our workshop provides a forum for discussing and advancing the state of the art in formal modelling and analysis using VDM and its family of associated formalisms including extensions for distributed VDM and real-time systems. We strongly welcome contributions on the development of tools for, as well as developments in, foundations and reports of practical experience. Each paper will be peer-reviewed by at least three members of the PC, must use the Springer LNCS format, and should not exceed 15 pages in length.

The scope of the workshop includes, but is not restricted to:
