| March 23, 1999 -- HOLD V Ada Version 1.0
was shipped to Lucas Aerospace,
part of TRW Inc. (NYSE: TRW), today.
This first version includes the safety-critical Ada compiler, run-time
system, libraries, with on-line and printed user documentation.
HOLD (High Order Language Demonstrators) are a series of projects that
explore the use of Ada programming technology within the development
processes of Lucas Aerospace's, digital engine controls business. This
activity is centred at the electronics centre of excellence at York Road,
Birmingham, England.
The development of safety critical software for such control systems is
the focus of the software engineering department. HOLD project objectives
are to develop software tools and methods that support the certification
or qualification of Ada based software at the highest criticality levels.
This means RTCA/D0-178B and DEF STD 0055/56.
For the majority of the systems/software work undertaken by Lucas
Aerospace, the Lucas proprietary LAPSE technology is used. This technology
is considered state of the art and easily allows projects to achieve level
'A' certification ratings.
HOLD projects seek to develop the Ada tools necessary to achieve the
same certification ratings for Ada 95 built software. All HOLD projects
have been part funded by the UK Ministry of Defence Procurement Executive
MOD(PE) and act on their behalf as stimuli to the RAPIDE Future systems
programme operated by MoD. |
HOLD III and V deal specifically with Ada
compilation issues surrounding the implementation of Ada 95 on safety
critical engine controllers. HOLD III uses customised XGC Ada 95 (A safety
critical subset) for implementation of a control system for an RB199 aero
engine based on the MC68020 processor. HOLD V builds on this technology
and has delivered an Ada 95 compilation system (again a safety critical
subset) targeted at Lucas Aerospace's new proprietary Microprocessor, the
LAe2000.
HOLD V feature list:
 | LAe2000 Target, Ada 95 compilation system |
| Safety critical Ada subset |
| Hosted on Solaris or Linux machines |
| Employs a RISC based instruction architecture |
| XGC derived compilation engine (based on GNAT) |
| Ada test suite validation possible |
| Interfaces to Lucas APSE (Ada Program Support Environment) |
HOLD V is currently a "live" project and is under test and
development.
