Hi-Lite is a project aiming at popularizing formal methods for the development of high-integrity software. It targets ease of adoption through a loose integration of formal proofs with testing and static analysis, that allows combining techniques around a common expression of specifications. Its technical focus is on modularity, that allows a divide-and-conquer approach to large software systems, as well as an early adoption by all programmers in the software life cycle.
Hi-Lite is completely based on libre software. The project is structured in two different toolchains for Ada and C based on GNAT/GCC compilers, the SPARK verification toolset and the Frama-C platform. The integration of these toolchains inside two industrial IDEs offers to the user a common interaction on Ada and C programs. In particular, mixed Ada/C programs can be verified against a common specification.
Project Hi-Lite has officially launched and we will be reporting on its progress here as it reaches major milestones throughout the evolution of the project.

A "Lighter" Introduction to Hi-Lite
Hi-Lite is based on powerful industrial tools that have been developed by the different partners for the last 10 to 25 years. In order to show you how Hi-Lite can improve on the existing state-of-the-art by creating new communications between these tools, we describe in the following the application of the various tools and techniques that are part of Hi-Lite to a very simple program.

The Workshop on Theorem Proving in Certification is now organized as a recurring event to compare approaches and tools based on theorem proving to critical software (such as avionics software), where a certification standard applies (DO-178B/C for avionics software). Here is the 2010 workshop and the 2011 workshop.
The tool ImProve performs formal verification (via model checking) on a small Embedded Domain Specific Language inside Haskell, and code generation to C.
Hi-Lite is an Open Source project financially supported by the French Government and the Essone general council in an effort to increase the use of formal methods in developing high-integrity software, particularly to meet the forthcoming DO-178C avionics standard.
The project partners are AdaCore, Altran, Astrium Space Transportation, CEA-LIST, the ProVal team of INRIA and Thales Communications. AdaCore is the project leader.
