How to Download and Use MISRA C:2012 Guidelines

MISRA C:2012 is the third edition of the MISRA C guidelines, which provide a set of best practices for developing safe, secure, portable and reliable software in the C programming language. MISRA C:2012 is widely adopted by developers in various industries, such as automotive, aerospace, medical devices, defense and railway. It is also cited by several standards, such as ISO 26262 and AUTOSAR.

In this article, we will explain how to download and use MISRA C:2012 guidelines for your software projects.

How to Download MISRA C:2012 Guidelines

The MISRA C:2012 guidelines are available for purchase from the MISRA website[^1^]. You can choose between a PDF version or a printed book. The PDF version costs Â15 (plus VAT) and the printed book costs Â25 (plus VAT). You can also purchase additional documents, such as MISRA Compliance 2020[^1^], which provides guidance on how to comply with MISRA C:2012 guidelines, MISRA C:2012 Amendment 2[^1^], which provides additional guidance on using C11 features with MISRA C:2012, and MISRA C:2012 Permits[^3^], which provides a set of permits to aid compliance in certain situations.

Once you have purchased the MISRA C:2012 guidelines, you will receive an email with a link to download the PDF version or a confirmation of your order for the printed book. You can also access your downloads from your account on the MISRA website.

How to Use MISRA C:2012 Guidelines

The MISRA C:2012 guidelines consist of 143 rules and 16 directives that cover various aspects of the C language and its usage. Each guideline is classified as Mandatory, Required or Advisory, depending on its importance and applicability. Mandatory guidelines must always be complied with, Required guidelines must be complied with unless subject to a deviation, and Advisory guidelines are considered good practice but compliance is less formal.

The guidelines are also categorized as Decidable or Undecidable, depending on whether they can be checked by an automated tool or not. Decidable guidelines can be checked by a static analysis tool that can detect all violations without any false positives or false negatives. Undecidable guidelines cannot be checked by a static analysis tool that can guarantee such accuracy, and may require manual inspection or other methods to verify compliance.

To use MISRA C:2012 guidelines effectively, you should follow these steps:

Select a suitable static analysis tool that supports MISRA C:2012 checking. There are several tools available that can check your code against the MISRA C:2012 rules and report any violations. Some examples are LDRA Testbed, PRQA QA-C, Parasoft C/C++test and IAR Embedded Workbench. You should choose a tool that meets your needs and budget.

Configure your static analysis tool to enable MISRA C:2012 checking. You may need to adjust some settings or options to enable the tool to check your code against the MISRA C:2012 rules. You should also specify which rules and directives you want to check, depending on your project requirements and preferences. You can use the default settings provided by the tool or customize them according to your needs.

Run your static analysis tool on your code and review the results. You should run your tool regularly on your code as you develop it, and review the results carefully. You should fix any violations reported by the tool as soon as possible, unless you have a valid reason to deviate from the guideline. You should also document any deviations and their justification in your project documentation.

Use other methods to check compliance with undecidable guidelines. For some guidelines that cannot be checked by a static analysis tool with sufficient accuracy, you may need to use other methods to verify compliance. These methods may include manual inspection, code reviews, testing, verification or validation activities. You should follow the guidance provided by the guideline i
