Frama-C One of the new features in Frama-C 18 (Argon) is the annotation @loop unroll, used by the Eva plug-in to replace and improve upon the usage of slevel for semantically unrolling loops. This new annotation is more stable, predictable, and overall more efficient. In this post we present the annotation...
Read MoreFrama-C chose to participate in the SATE VI Ockham Sound Analysis Criteria. With the upcoming Frama-C 18 (Argon) release, results can be reproduced using the open source version of the Eva plug-in. This post briefly presents SATE, the Juliet test suite, and the results obtained with Frama-C 18. We then...
Read MoreA recurring subject when using Frama-C, especially intriguing for newcomers, is how to reach the stage where parsing of a realistic code base (as in, one that uses external libraries and compiles to different architectures) succeeds. This post will show a bit of the depth involved in the subject, presenting...
Read MoreChrony is an implementation of NTP which is C99-compatible, with portable code, and thus a good candidate for an analysis with tools such as Frama-C. As part of an effort sponsored by Orolia, researchers from the List, CEA Tech laboratory applied Frama-C/Eva on the Chrony source code, in an attempt...
Read MoreIn the previous post, we used analysis-scripts to prepare our analysis of Recommender. In this post, we will run EVA on the code and see how the iterative refinement of the analysis can be done. We assume the reader has performed all of the steps in the previous post, and...
