Description-en: Software verification platform
Why3 is a platform for deductive program verification. It provides a
rich language for specification and programming, called WhyML, and
relies on external theorem provers, both automated and interactive,
to discharge verification conditions. Why3 comes with a standard
library of logical theories (integer and real arithmetic, Boolean
operations, sets and maps, etc.) and basic programming data
structures (arrays, queues, hash tables, etc.). A user can write
WhyML programs directly and get correct-by-construction OCaml
programs through an automated extraction mechanism. WhyML is also
used as an intermediate language for the verification of C, Java, or
Ada programs.
.
Why3 is a complete reimplementation of the former Why platform. Among
the new features are: numerous extensions to the input language, a
new architecture for calling external provers, and a well-designed
API, allowing to use Why3 as a software library. An important
emphasis is put on modularity and genericity, giving the end user a
possibility to easily reuse Why3 formalizations or to add support for
a new external prover if wanted.
