The next training B will be a level 2 session and will take place from 24 to 27 July 2017 in Paris. Remember to sign up!
The new version 4.4.2 of the AtelierB toolset for the B method has been released. This comes with numerous bug fixes and several feature improvement that will be introduced. The most interesting feature is probably the new capability of proof obligations visualisation and management directly within the editor. We have also two new capabilities for the interactive proof and additions to the proof rules management tools.
The seminar, entitled “Proven software with B executing on Low Cost High integrity Platform”, is aimed at presenting the latest innovations concerning the use of the B formal method for the development of safety critical systems:
“Atelier B has been heavily used in industry, mainly in the railways, for the development of proven safety critical softwa
LCHIP project (Low Cost High Integrity Platform) will ease development of safety critical systems and software up to SIL4, the highest Safety Integrated Level. LCHIP platform is a combination of a B method (formal method) Integrated Development Environment and a secured runtime platform able to execute software in real-time.
At the occasion of the ABZ 2016 conference (http://www.cdcc.faw.jku.at/ABZ2016/) which took place in Linz (Austria) on May 23-27 2016, ClearSy was invited to present the last 20 years of development and industrial use of Atelier B, and to expose forthcoming innovations including functional modelling (Abstract Model Editor), improved automatic proof and low-cost high-integrity platform (LCHIP).

At the occasion of the ABZ 2014 conference, a tutorial on formal data validation is organized at ENSEEIHT together with workshops (see details here). The tutorial will happen on June 3rd 2014 from 2:00 pm to 5:30 pm. During this tutorial, formal data validation principles will be exposed (key concepts, mathematical language to express properties, […]
Atelier B 4.2.1 Free is available for download. It corrects the errors related to the introduction of the new tool bxml and the lack of default values for the required resources.
New bxml tool included in atelier B 4.2 Free is not working properly as required resources are missing. When used, error messages “Bxml error for …” are displayed. The turnaround consists in adding the following lines: ATB*ATB*Proof_Obligations_Generator_NG_Command: pog ATB*ATB*Bxml_Command: bxml to the AtelierB file. A new version 4.2.1 is being cooked and should be available […]
