Chosen excerpts: “embedding of contracts as code is a better approach”; “The language of conditions is just the language of expressions in the programming language used”; “ForAll and Exists that work over integer ranges and collections”; “Any methods called from within contract expressions should be pure methods”; “Runtime contract checking is particularly eff ective in conjunction with automated testing”; “generating good documentation from the embedded contracts is a key scenario”.

And the conclusion: “Since contract expressions are compiled by the existing compiler, the typical problem of having the speci cations and the code drift apart due to edits, refactoring, etc., is avoided.”

All of this supports the vision of project Hi-Lite, and provides valuable experience reports which should inspire us in Hi-Lite.

“Object and Source Coverage for Critical Appl ications with the Couverture Open Analysis Framework“.

It presents the Couverture approach to object and structural coverage analysis for certified safety-critical applications, in particular in the context of DO-178.

Peter has twenty years experience in languages and software development methodologies and acts as the focal point for UML in Silver Atena. His talk surveys Agile methods and formulates a list of features that occur in these methods, then considers whether each of the features can be applied in the field of safety-critical software development.

This paper describes how the Couverture technology copes with the “Souce Code VS Object Code Coverage” debate in a DO-178 context.

The Couverture project is hosted on the Open-DO Forge.

The attached paper is also published in the Ada User Journal, December 2009 issue.

These events were a big success and attracted more than 450 attendees! I would like to thank one more time the CARA who did a very good job at organizing these.

The presentations were of very high quality and their diversity pleased practionners as well as managers and students. All the slides are accessible on the CARA’s website (French and English).

I gave a talk in Grenoble and Valence about the infrastructure and processes we put in place at AdaCore to build and test on a daily basis all our compilation chains and accompanying technology in a Lean fashion.

I also presented the “qualification machine” we have built based on open source technology to ease the DO-178B tool qualification process by adopting an agile philosophy.
