Praxis and AdaCore Announce SPARK Pro


New open source tool suite improves high assurance software projects

NEW YORK, PARIS and LONDON - Ada UK Conference - Developers creating safety critical and high assurance systems will benefit from today’s launch of SPARK Pro. The new open source development environment has been created by Praxis, international specialist in critical systems engineering, and AdaCore, the leading provider of commercial software solutions for the Ada language.

SPARK Pro combines the proven SPARK language and supporting toolset with AdaCore’s easy-to-use GNAT Programming Studio (GPS) Integrated Development Environment, backed by unrivalled support services. This provides a powerful method for developing critical systems.

Developed by Praxis, SPARK is a language specifically designed to support the development of software used in applications where correct operation is vital either for reasons of safety or security. The SPARK Toolset offers static verification that is unrivalled in terms of its soundness, low false-alarm rate, depth and efficiency. The toolset also generates evidence for correctness that can be used to build a constructive assurance case in line with the requirements of industry regulators and certification schemes. There are versions of SPARK based on Ada 83, Ada 95, and Ada 2005, so all leading Ada compilers and tools work out-of-the-box with SPARK.

The new development environment will be globally available from AdaCore, with support delivered by both companies using AdaCore’s web based GNAT Tracker support system. Existing SPARK users have the option to transition to the new environment, which is also available as a standalone product. The launch of SPARK Pro is the first available product following the technical and marketing partnership announced in Q4 2008 between Praxis and AdaCore.

“SPARK continues to be used for the development of new, advanced, critical systems as well as support of existing operational systems, so it is vital that it continues to develop – SPARK Pro is a major step forward in usability and support through our partnership with AdaCore,” said Keith Williams, Praxis Managing Director. “The launch of SPARK Pro integrates the strengths of the best development tools in the market. Our partnership combines our proven expertise with AdaCore’s user interface, global reach and support systems to deliver the perfect solution for safety and security developers. This is great news for the SPARK language and our existing and future customers.”

“AdaCore and Praxis share a commitment to enabling high-quality, high-integrity development,” said Robert Dewar, AdaCore President and CEO. “I am excited by the possibilities of this partnership. The SPARK technology is an outstanding demonstration of the fact that formal methods technologies are practical today, and hold enormous promise for the future. The launch of SPARK Pro, which integrates SPARK Pro and GNAT Pro into a coherent FLOSS tool set and environment, extends the benefits of SPARK to existing and new GNAT Pro users. I expect this combination to play a major role in high-integrity development, especially for the increasingly important security-critical area”.

“Praxis has worked with AdaCore for many years and the development of common technology was the next logical step,” said Sylvain Haman, Praxis Director. “SPARK Pro will enable our clients world-wide to ensure correctness of their software while enjoying the convenience of an enhanced development environment.”

Praxis and AdaCore have a long history of working together on high profile systems. These include the Tokeneer project developed by Praxis for the US National Security Agency (NSA) using the SPARK Ada language and toolset and AdaCore GNAT Pro.

A joint webinar between AdaCore and Praxis to discuss the benefits and provide a demonstration of SPARK Pro will be held on April 21, 2009. It will begin at 5pm European Daylight Time/4pm GMT Daylight Time/11am Eastern Daylight Time/8am Pacific Daylight Time. To register please visit
