Produce maintainable and debuggable code, for example, naming conventions and commenting.Avoiding using functions and constructs that are prone to failure, for example, malloc may fail.Avoiding possible compiler differences, for example, the size of a C integer may vary but an INT16 is always 16 bits.The rules can be divided logically into a number of categories: Advisory guidelines are considered good practice, but compliance is less formal.Required guidelines shall be complied with, unless subject to a Deviation.Mandatory guidelines shall always be complied with.Furthermore, the MISRA Compliance document permits Advisory guidelines to be Disapplied. Classification Įach Guideline is classified as Mandatory (new for MISRA C:2012), Required or Advisory.
Previous standards are still available for use with legacy software projects that need to refer to it. When a new software project is started, the latest MISRA standard should be used. Guideline classification and categorization
The AUTOSAR 4.3 General Software Specification requires that If the BSW Module implementation is written in C language, then it shall conform to the MISRA C:2012 Standard. The AUTOSAR 4.2 General Software Specification requires that If the BSW Module implementation is written in C language, then it shall conform to the MISRA C:2004 Standard. The AUTOSAR General Software Specification (SRS_BSW_00007) likewise cites MISRA C:. ISO 26262-6:2018 Part 6: Product development at the software level cites MISRA C:2012.ISO 26262-6:2011 Part 6: Product development at the software level cites MISRA-C:2004 and MISRA AC AGC.
ISO 26262 Functional Safety - Road Vehicles cites MISRA C as being an appropriate sub-set of the C language:. The NASA Jet Propulsion Laboratory C Coding Standards are based on MISRA-C:2004. The Joint Strike Fighter project C++ Coding Standards are based on MISRA-C:1998. With the publication of MISRA C:2012 a new category of Guideline was introduced - the Directive whose compliance is more open to interpretation, or relates to process or procedural matters.Īlthough originally specifically targeted at the automotive industry, MISRA C has evolved as a widely accepted model for best practices by leading developers in sectors including automotive, aerospace, telecom, medical devices, defense, railway, and others. Third edition: 2012 (directives rules, Decidable/Undecidable)įor the first two editions of MISRA-C (19) all Guidelines were considered as Rules. Second edition: 2004 (rules, required/advisory). First edition: 1998 (rules, required/advisory).
