RSSR is a new conference focused on the development and verification of railway systems. We will present there how SPARK can be used to write abstract software specifications, whose refinement in terms of concrete implementation can be proved automatically using SPARK tools.
We are pleased to announce that we will be a major sponsor and exhibitor at ERTS, Toulouse and will be exhibiting at Embedded World, Nuremberg in the coming months!
The three of us attended the Ada Lovelace Symposium in Oxford (UK). The two days were one fantastic discovery after another about the life, achievements and legacy of Ada Lovelace, the programming pioneer who lent her name to the Ada language.
We are excited to be sponsoring and exhibiting at the 2nd annual High Integrity Software conference, taking place on 5th November 2015 at The Royal Marriott Hotel in Bristol.
AdaCore has a long history of providing tools and support to develop mission critical applications for Space. Check out this video we made and showed at the conference to see which ones!
Project-P Open Workshop
In a recent article in Communications of the ACM, Carl Landwehr, a renowned scientific expert on security, defends the view that the software engineering community is doing overall a poor job at securing our global information system and that this is mostly avoidable by putting what we know works to work, to the point that most vulnerabilities could be completely avoided by design if we cared enough. Shocking! Or so it should appear.
Embedded News TV caught up with our own Matteo Bordin to talk about QGen. Matteo provides a nice overview of QGen and it's position in the industry as the need for safe and secure software becomes increasingly important.
20 Years of AdaCore: Company as Committed as Ever on Safety-Critical Software Solutions
For lovers of verification tools and critical system (we know you're out there!), we are very excited to present ProofInUse!
If you have a passion for Ada, need more information on our technology or would just like to have a chat, there are a couple of upcoming events where we'd love to meet up. What's more, we'll be launching our brand new product QGen at Embedded World!
I'm proud, if not a bit nervous, to be the one firing the very first post on this brand new blog. Why are we starting a corporate blog at this time? There are many reasons for this. The main one is that there are many things happening at AdaCore and around the GNAT technology and we are seeking better ways to make them widely known while offering interested recipients the possibility to react and interact with us.
Correctness of robot software is a challenge. Just proving the absence of run-time errors (AoRTE) in robot software is a challenge big enough that even NASA has not solved it. Researchers have used SPARK to do precisely that for 3 well-known robot navigation algorithms. Their results will be presented at the major robotics conference IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2014) this coming September.
In this article, we provide a short introduction to our paper at the Test and Proof 2014 conference in York, UK.
Using SPARK or any other formal method in a certification requires that the applicant agrees with the certification authority on the verification objectives that this use of formal methods allows to reach, and how this is obtained and documented. In order to facilitate this process, the participants to the workshop on Theorem Proving in Certification have produced a draft set of guidelines, now publicly available.
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!
