Yannick Moy
Yannick Moy is Head of the Static Analysis Unit at AdaCore. Yannick contributes to the development of SPARK, a software source code analyzer aiming at verifying safety/security properties of programs. He frequently talks about SPARK in articles, conferences, classes and blogs (in particular blog.adacore.com). Yannick previously worked on source code analyzers for PolySpace (now The MathWorks) and at Université Paris-Sud.
For All Properties, There Exists a Proof
With the recent addition of a Manual Proof capability in SPARK 18, it is worth looking at an example which cannot be proved by automatic provers, to…

Physical Units Pass the Generic Test
The support for physical units in programming languages is a long-standing issue, which very few languages have even attempted to solve. This issue…
Prove in the Cloud
We have put together a byte (8 bits) of examples of SPARK code on a server in the cloud. The benefit with this webpage is that anyone can now…
SPARK Tutorial at FDL Conference
Researcher Martin Becker is giving a SPARK tutorial next week at FDL conference. This post gives a link to his tutorial material (cookbook and…
New SPARK Cheat Sheet
Our good friend Martin Becker has produced a new cheat sheet for SPARK, that you may find useful for a quick reminder on syntax that you have not…
Proving Loops Without Loop Invariants
For all the power that comes with proof technology, one sometimes has to pay the price of writing a loop invariant. Along the years, we've strived to…
Research Corner - Focused Certification of SPARK in Coq
The SPARK toolset aims at giving guarantees to its users about the properties of the software analyzed, be it absence of runtime errors or more…
Applied Formal Logic: Searching in Strings
A friend pointed me to recent posts by Tommy M. McGuire, in which he describes how Frama-C can be used to functionally prove a brute force version of…
Research Corner - FLOSS Glider Software in SPARK
Two years ago, we redeveloped the code of a small quadcopter called Crazyflie in SPARK, as a proof-of-concept to show it was possible to prove…
Research Corner - Floating-Point Computations in SPARK
It is notoriously hard to prove properties of floating-point computations, including the simpler bounding properties that state safe bounds on the…
Frama-C & SPARK Day Slides and Highlights
The Frama-C & SPARK Day this week was a very successful event gathering the people interested in formal program verification for C programs (with…
