    ARTiMon - verification of temp-logic properties over flow of events

    AdaCore Internal Seminar - March 22, 2011

    ARTiMon - verification of temp-logic properties over flow of events. ARTiMon is a tool which analyzes on-the-fly a flow of dated observations in order to detect hazards expressed in its formal entry language (a temporized logic). A flow may stem from the instrumentation of a natural object, from the simulation of a model, the execution of a code or a system.

    ARTiMon can then be used in the design process of complex systems, for model validation, system testing or as an embedded controller. ARTiMon works in variable-step or in fixed-step mode and has no limitation about the length of flow. This is the only tool gathering all those features.

    Presenter: Nicolas Rapin - CEA/list researcher.

    AdaCore, from time to time, organizes seminars in the Paris offices. If you are interested in a particular talk, please send email to events@adacore.com.

    Webinar - Introducing CodePeer

    Tuesday, March 9, 5:00pm CET / 11:00 am EST / 8:00 am PST

    CodePeer - Source Code Analysis Tool

    Recently launched, CodePeer is a source code analyzer that detects run-time and logic errors in Ada programs. Serving as an efficient and accurate code reviewer - in effect an expert assistant. CodePeer identifies constructs that are likely to lead to run-time errors such as buffer overflows, and it flags legal but suspect code typical of logic errors. Going well beyond the capabilities of typical static analysis tools, CodePeer also produces a detailed analysis of each subprogram, including pre- and postconditions.

    This webinar will describe and demo some of the features of CodePeer and allow you to ask questions directly to the designers of the tool. To register, please visit:

    Qualifying Machine project launched on Open-DO

    A Qualifying Machine (QM) is an agile and lean infrastructure to ease DO-178 tool qualification. The main goal of a QM is to ease the manipulation of all artifacts within the whole application life cycle and to track the activities performed by the development team.

    Within Open-DO, we released an instantiation of the QM concept for GNATcheck, a coding standard checking tool qualifiable for DO-178. The infrastructure and qualification material (including the Tool Qualification Plan and the testing framework) are freely available as open source in the Open-DO forge. With this initiative, we intend to promote open collaborations in the high-assurance domain and to show how to deploy a lean and agile qualification process.

    You can get more information on the Open-DO Qualifying Machine and download its instantiation for GNATcheck here.

    Coverage Project

    Thanks to French public funds, the next generation of Free Software code coverage tools is on its way. “Project Coverage” will produce a Free Software coverage analysis toolset together with the ability to generate artifacts that allow the tools to be used for safety-critical software projects undergoing a DO-178B software audit process for all levels of criticality.

    While an important target use of the coverage toolset is safety-critical embedded applications, the design of the tools allows its use in non safety-critical projects.

    Beyond the production of useful tools and certification material for industrial users, an important goal is to raise awareness and interest about safety-critical and certification issues in the Free Software/Open Source community.

    The key insight of “Project Coverage” is as follows: code coverage can greatly benefit from recent advances in hardware virtualization technology as promoted, for instance, by QEMU.

    The attached slides give a presentation of the technical scope of the project.

    Webinar: GNAT Pro for OpenVMS on HP Integrity servers

    GNAT Pro for OpenVMS on HP Integrity servers training webinar - Nov 20, 2007.

    AdaCore’s GNAT Pro for HP OpenVMS I64 is a full-featured Ada development environment offering a natural migration path for Ada applications from other platforms. It includes a compiler that can handle all three versions of the Ada standard — Ada 83, Ada 95, and Ada 2005 — and provides a rich set of auxiliary tools and an extensive set of libraries. Ada-aware debugging is provided through HP’s OpenDebug.

    In this half-hour webinar AdaCore, with HP’s participation, will describe the features and benefits of the GNAT Pro Ada development environment on HP OpenVMS I64 and answer questions from the audience. A particular focus will be on how to port Ada code from HP Ada on VAX and Alpha servers to GNAT Pro on OpenVMS I64. GNAT Pro supplies an extensive set of pragmas and attributes that are compatible with HP Ada, and for most Ada code the porting process should be reasonably straightforward. For those situations where the program makes architectural assumptions that do not apply to I64 (for example 32- bit addresses) the webinar will identify the issues and offer effective solutions.

    New stage in the transition to GNAT Pro based on gcc 4.1 backend

    We are in the process of transitioning the GNAT Pro technology to a new compiler back-end based on GCC 4.1 which we expect to bring significant performance improvements to user applications. Our goal is to have several of our supported configurations on this back-end for the next major GNAT Pro release scheduled early 2007. We have been able to make significant progress in the areas of general stability and in the support for numerous platforms thanks to invaluable input provided by our customers. This latest beta version includes support for most of the new Ada 2005 features and is our most advanced Ada 2005 technology.

    Please do not hesitate to contact us if you have any questions concerning this program.

    New Version Numbering for GNAT Pro

    In 2007 AdaCore will be moving to a new numbering scheme for product releases. Instead of two-part version numbers such as 3.15a or 5.04a1, we will be using the more common convention of three numbers separated by dots. The first number, as at present, will identify a major release and will thus indicate the introduction of significant new functionality. The second number will correspond to the digits after the dot in the current scheme. And the third number will replace the suffix (such as "a" or "a1") used at present. "0" as the third number will be used for a beta version, "1" for an initial release, and higher numbers for subsequent releases.

    In order to acknowledge the full support for the new Ada 2005 features, the GNAT Pro major version number is moving to the 6 series. More specifically, the version scheduled for Q1 2007 will be 6.0.1, and the follow-up release scheduled for later in the year will be 6.0.2. The planned releases in 2008, incorporating enhancements to be made during 2007, will then be 6.1.1 and 6.1.2.

    Customers can find more information in the "Our support policy" on GNAT Tracker.

    AdaCore Quality Process
    The Nov 2006 online issue of CrossTalk sees an interesting article on AdaCore's quality assurance processes and tools:

    "A software product is rarely a static artifact resulting from a one-time effort; it needs to evolve via periodic updates, to correct defects or meet new requirements, and it may need to be ported to multiple machines and/or operating systems. The development team might be distributed geographically, requiring careful coordination. A software producer must have well-defined processes for dealing with these issues, to ensure that its products successfully meet users’ needs."

    Independent control of extra paren check
    The warning check for extra parens around conditional expressions has been removed from the redundant construct warning, and been replaced by a new style option -gnatyx (STYLE_CHECKS=XTRA_PARENS in VMS) which controls this specific check. This change reflects the observation that this is really more of a style check, and also allows it to be controlled independently of the other useful redundant construct warnings.

    Improved definition of No_Streams
    The restriction No_Streams is now more useful. It only disallows actual creation of objects of a stream type (by either an object declaration or an allocator). But it does not disallow withing Ada.Streams, which means that library packages with such with statements can still be used, provided no stream object is created.
