Why use Atelier B 4?
Atelier B 3.7 went through numerous improvements and changes to finally become Atelier B 4. Here is an overview of the main changes in this new version:
> Availability of the tool in Linux, Solaris, Mac OS X and Windows, thanks to the development of the graphic interface in the Qt environment and the transfer of the Atelier B core tools.
> New graphic interface that offers, in particular:
– An all-in-one overview of the projects and their status, a better integration of error messages.
– The inclusion of a task distributor: the development tasks (type verification, generation of proof obligations, automatic proof, code generation) can be distributed among a pool of servers. The interface allows for the adding, deleting and interrupting of these tasks.
– A reworked proof interface with better management of the proof tree, simplified access to proof commands, the addition of user rules and the syntactic analysis of formulas.
– An editor with browsing and automatic completion that supports the B Language and Event-B. (Event-B).
> Integration of the proof of the proper definition of models: automatic, integrated creation of a proper definition project associated with a main project to validate the proper definition of models.
Addition of improved proof tools for rules.
> Addition of an automatic refinement tool (BART)
> Addition of a B0 implementation translator towards the language (ComenC)
> Event-B support with syntactic controls and the generation of specific proof obligations
> Addition of a simple, effective means of interfacing with external tools.
