Subsets of MISRA-C 2004 rules, and quality objectives - reito - 30-12-2014 Dear colleagues, I have received a paper where the authors talk about three different "subsets of MISRA-C 2004 rules". Each subset is related to a different "quality objective", that are in turn related to the SW criticality. I have checked the MISRA-C 2004 document and I think that it does not contain any reference to these "rule subsets", with the exception of the advisory or required character and the classification of the rules by type. I would like to know if this practice (having "rules subsets") is common in the automotive industry, and whether there is a shared reference to make this categorization of the rules subsets depending on the SW criticality. Thanks in advance, Ricardo Re: Subsets of MISRA-C 2004 rules, and quality objectives - misra-c - 27-01-2015 MISRA has published no "subsets of MISRA-C:2004 rules", other guidelines for the application of MISRA-C:2004 in the context of automatic code generation. This document can be purchased from the misra.org.uk website: Quote:MISRA AC AGC: Guidelines for the application of MISRA-C:2004 in the context of automatic code generation, ISBN 978-906400-02-6 (PDF), November 2007.Section 5.1.2 of the MISRA-C:2004 guidelines permits a project to choose whether advisory rules need a formal deviation in the same way as required rules. Section 4.3.2 permits a “Project Deviation†to relax a required rule in specified circumstances. The method by which project deviations are created will differ depending on the organisation and is likely to happen at the start of a project. |
