Tool suite supports MISRA C++:2008

LDRA has enhanced the capabilities of the LDRA tool suite to comply with the released version of the MISRA C++:2008 standard from the Motor Industry Software Reliability Association (MISRA). MISRA is a standard directed by the automotive industry but it has gained widespread acceptance in other vertical markets such as rail, aerospace, military, and medical sectors.

MISRA represents a collaboration between automotive manufacturers, component suppliers and engineering consultancies that seeks to promote best practice and commonality in the development of safety-related automotive electronic and other embedded systems through the publication of standard guidelines. Since its launch, the success of MISRA C as a "best practice" solution has not only seen its application spread throughout the worldwide automotive industry, but it has also been increasingly adopted for safety-related and safety-critical software development projects and applications in a wide variety of industries.

With the success of the MISRA C standard, a MISRA C++ working group was established in 2005 to create similar guidelines for the C++ programming language. The MISRA C++:2008 subset is suitable for use in critical systems.

C++ is now being used for automotive systems, as well as in critical systems within other industrial sectors such as aerospace, medical and nuclear. While numerous guidelines existed for the use of C++, prior to the formation of this standard, there was no de-facto standard. Additionally, these did not include guidance for all areas of the C++ language and any errors associated with these that could remain undetected.

The MISRA C++ subset has been produced using techniques similar to those used within MISRA C. It draws together existing C++ guidelines (from many, diverse sources) and significantly enhances the state-of-the-art. The guidelines have been written in a way that makes them accessible to the majority of programmers.

Chris Tapp, LDRA Field Application Engineer and MISRA C++ Chairman commented, "MISRA C++ has drawn together many of the existing guidelines available that help reduce the number of defects found within C++ code. The addition of guidance in the areas of templates, inheritance, and exceptions significantly advances the state-of-the-art in the use of C++ for critical systems."

Tapp added, "It is the hope of the MISRA consortium that MISRA C++ will gain industry acceptance, and that the adoption of a safer subset will become established as a best practice both by vehicle manufacturers, component suppliers and other industrial sectors. It should also encourage training, and enhance competence in C++ programming at both individual and company levels."

The support for C++ compliance builds on LDRA's extremely powerful support for the C language where support is available for the MISRA C:1998 and MISRA C:2004, HIS (Herstellerinitiative Software), GJB (Chinese Military Standard), CAST (China Academy of Space Technology) and CMSE (China Manned Space Engineering project) standards for the C programming language.
