A proof obligation generator for VDM-SL
[chapter]
1997
Lecture Notes in Computer Science
In this paper an extension of the IFAD VDM-SL Toolbox with a proof obligation generator is described. Static type checking in VDM is undecidable in general and therefore the type checker must be incomplete. Hence, for the "difficult" parts introducing undecidability, it is up to the user to verify the consistency of a specification. Instead of providing error messages and warnings, the approach of generating proof obligations for the consistency of VDM-SL specifications is taken. The overall
