GNAT Pro Safety-Critical is ideal for developing systems that must meet the RTCA DO-178B / DO-178C (EUROCAE ED-12B / ED-12C) certification standards for airborne software.
GNAT Pro Safety-Critical is a complete development environment -- an enhanced version of GNAT Pro designed for building safe and secure software. Through its specially designed run-time libraries and its comprehensive tool suite, it helps reduce the cost of developing and certifying systems that have to meet software standards such as RTCA DO-178B / DO-178C (also known as EUROCAE ED-12B / ED-12C). The product’s fully configurable and customizable run-time libraries include several predefined profiles corresponding to particular sets of features that are especially applicable in real-time systems requiring safety certification.
Avionics Industry Standards
The purpose of RTCA DO-178B / EUROCAE ED-12B is to provide “guidance for determining, in consistent manner and with an acceptable level of confidence, that the software aspects of airborne systems and equipment comply with airworthiness requirements.” The guidance comprises:
Objectives related to the various software life cycle processes
Activities for achieving these objectives
Artifacts (life cycle data) demonstrating that the objectives have been met
The document discusses those aspects of airworthiness certification that pertain to the production of software for airborne systems and equipment used on aircraft or engines.

The RTCA/EUROCAE DO-178B/ED-12B avionics safety standard went through a revision that ended with the publication of the new DO-178C/ED-12C standard in December 2011. The core document is substantially the same as DO-178B, with a number of clarifications and a few minor corrections. The major effect of the update effort is
the creation of a new "Tool Qualification Considerations" document and three supplements that adapt the core document guidance when specific technologies are used: "Model-Based Development and Verification", "Object-Oriented Technology and Related Techniques", and "Formal Methods". AdaCore participated in the DO-178C revision process, with Dr. Cyrille Comar contributing to the subgroup on Object-Oriented Technology and Related Techniques.
The Ada language and the AdaCore tools that are designed to help in DO-178B certification are equally useful for the new DO-178C standard. These include GNAT Pro Safety-Critical, SPARK Pro, GNATcoverage, GNATcheck, GNATstack, Qualification material, Traceability studies, specific runtimes, etc.

CodePeer has been qualified as a Verification Tool under DO-178B, a software standard for commercial airborne systems, automating a number of activities associated with that standard’s objectives for software accuracy and consistency. CodePeer has also been qualified for EN50128, the highest international standard for safety integrity concerning software for railway control and protection. The EN50128 qualification material addresses boundary value analysis (detecting errors such as buffer overflow), control flow analysis (detecting errors such as unreachable code), and data flow analysis (detecting errors such as references to uninitialized variables).
