Plug-in Proof Support for Formal Development Environments

A number of industrial software development standards mandate that safety-critical software components be developed using formal methods, including formal verification. While formal development is supported by a number of formal development environments, verification of correctness properties is still a major bottleneck. Most formal development environments provide built-in facilities for discharging these correctness properties (so-called proof obligations). However these built-in tools are typically less mature and sophisticated than stand-alone theorem provers. FDEs would benefit from being able to use a variety of theorem provers to discharge proof obligations, where different provers can be selected for different
