  • Media Release January 29Th, 2019
    Media Release January 29th, 2019 MISRA consortium announce integration of AUTOSAR C++ coding guidelines into updated industry standard Two world leading consortiums in coding guidelines, MISRA and AUTOSAR, have today announced that their industry standard for best practice in C++ will be integrated into one publication. The goal is to provide a common set of rules, supporting software development in a number of innovative sectors. In 2008 MISRA, a consortium of manufacturers, component suppliers and engineering consultancies, published MISRA C++, a language subset that outlined expert guidance for C++ programming. Based on this publication, AUTOSAR started to develop their own guidelines. AUTOSAR has released their C++ guidelines as part of the Adaptive AUTOSAR platform twice a year since March 2017. This paved the way for the E/E development with the focus on performance as well as safety and security. MISRA will merge the AUTOSAR guidelines with its own established best practice to develop a single ‘go to’ language subset for safety-related C++ development. The MISRA led guidelines will incorporate the latest version of C++ language - C++17 - and, when available, its successor C++20. The new guidelines for the safe and secure application of both embedded control systems and standalone software will provide the framework for C++ use in several fields of application. This includes sectors such as automotive, aerospace, telecommunications, medical devices, defense and engineering. Chris Tapp, Chair of the MISRA C++ Working Group, said, “We have a proud history in producing coding guidelines and we are excited to continue developing the industry standard for years to come.
