My colleague Matteo Bordin will present at the upcoming Embedded Real Time Software and Systems conference in Toulouse in February a case study showing how formal verification with SPARK can be included in a larger process to show preservation of properties from the system level down to the software level. The case study is based on the Nose Gear challenge from the Workshop on Theorem Proving in Certification.
The University of Applied Sciences Rapperswil in Switzerland has released last week an open-source separation kernel written in SPARK, which has been proved free from run-time errors. This project is part of the secure multilevel workstation project by Secunet, a German security company, which is using SPARK and Isabelle to create the next generation of secure workstations providing different levels of security to government employees and military personnel. I present why I think this project is worth following closely.
We will present three case studies using SPARK 2014 at the upcoming Embedded Real Time Software and Systems conference in Toulouse in February 2014, in three different domains: rail, space and security. The lessons learned in those three case studies are particularly interesting. Here is the companion paper that we wrote.
David Lesens from Astrium was a member of the Hi-Lite project ("was" because the project is finished now, see the previous post), and has tried GNATprove - the formal verification tool for SPARK 2014 - on space vehicle software as an industrial case study of the project. And it turns out GNATprove performed pretty well!
