BOSTON -- December 04, 2012

ACM SIGAda HILT Conference--AdaCore today announced the successful usage of
its Code Traceability Analysis for DO-178B by Rockwell Collins in the
certification of the Integrated Display System (IDS) for a large,
next-generation, commercial aircraft. The Traceability Analysis package is
part of the evidence needed to satisfy the DO-178B objectives for structural
code coverage at Level A, the highest (most stringent) level for avionics
software safety.

The IDS, featuring Rockwell Collins’ EFIS/EICAS Interface Unit (EIU-7001),
includes many of the advanced features found on the Boeing 787, such as an
electronic checklist with cursor control panel, navigation performance scales
and vertical situation displays. This critical system is Level A and was
developed in Ada using AdaCore’s GNAT Pro High-Integrity Edition for DO-178B,
targeted to PowerPC-ELF and using the Zero Footprint (ZFP) run-time library.

Certification at Level A is a major effort, involving a variety of software
life cycle processes. One of the verification process activities entails
demonstration of complete coverage of the source code through
requirements-based tests. If any object code is not traceable to the source
code (for example, if a high-level source construct is compiled into complex
object code involving conditional instructions) then DO-178B specifies the
following activity: ‘additional verification should be performed on the object
code to establish the correctness of such generated code sequences’. AdaCore
has developed an infrastructure and methodology to perform this activity; the
product of this activity is a source-to-object Code Traceability Analysis.

AdaCore’s approach has been successfully used in the past, saving customers
time and effort in conducting DO-178B certification. In light of this
successful previous experience, Rockwell selected AdaCore to conduct an
analogous traceability analysis for this next generation IDS Program. Rockwell
has now successfully completed the certification of its IDS, with AdaCore’s
Traceability Study serving as part of the full certification evidence.

“The traceability analysis that is needed to meet the structural code coverage
objectives requires a detailed knowledge of both the source language semantics
and the generated object code,” said Robert Dewar, AdaCore President and CEO.
“With our expertise in the Ada language and compiler technology, AdaCore was
uniquely qualified to perform this analysis both accurately and efficiently.
This allowed Rockwell Collins engineers to devote their energies to
certification activities directly related to their actual application.”
