ATELIER B FREE DOWNLOAD

The Atelier B V4 is distributed free of charge, through its Community Version, to all those who wish to use Atelier B for research, teaching and development of their industrial projects. As soon as the tool is used for the first time it is allocated for an unlimited time.

The atelier B V4 comprises all the tools required for developing an industrial project and is available in WINDOWS, MAC and LINUX.

Users, companies and research or teaching organisations can subscribe to a maintenance contract for the latest version (corrective or with new functional features). The licence contract supplied with Atelier B can be obtained upon request, in French and English, at atelierb (at) clearsy (dot) com .

  • The addition of an extensible mechanism allowing the integration without recompilation of external provers (CVC4 and Z3 by default), in order to improve the automatic proof performance. This version is used industrially by Alstom, RATP and Siemens Transportation Systems.
  • Improved support for event-driven B for Common Criteria certification
  • Several improvements for both the automatic and interactive prover UI
  • New options to particularize the behaviour of the new proof obligation generator
  • Event-B manual available in the Help/Manuals section

4.6

  • Atelier B CSSP: B modelling and application programming for CLEARSY Safety Platform starter kit SK0
  • Atelier B now supports macOS 10.15 « Catalina »
  • Interactive proof
    • Saved proofs can now be replayed until the first failing command
    • User pass can now be saved in the patchprover file
  • Project management
    • Improvement of the use of MANIFEST
    • MANIFEST files can now be used through the console
  • Translator
    • C4B: add the translation of tables indexed by an enumeration.

    • Event-B: add the WITNESS keyword
    • Consolidation of PO generation
  • Addition of the proof obligation generator parametrization manual

4.5

  • Simplified installation with Linux (Universal Installer)

  • Interfacing tool « IAPA » (Linux only) to connect with provers from Why3 platform
  • Interactive proof
    • New feature to use SMT solvers to define proof rules applying to the current goal
    • New feature to add its own groups of proof commands
    • Improvement in typing of proof commands

  • A better integration of real and floating point numbers
  • Accessors added to BART in order to solve refinement conflicts
  • Boolean and integer translation fine-tuning in C4B code generator
  • Addition of a proof server, in order to speed up proof

4.1
