MISRA-C Training

MISRA (the Motor Industry Software Reliability Association) provides guidelines for developing safety- and security-related electronic systems, embedded control systems, software-intensive applications, and standalone software.

The MISRA C standard includes code safety, portability, and reliability guidelines for the C programming language.

The first set of guidelines was released in 1998, which were specific to the C language. However, since then, the MISRA Consortium also develops coding standards for C++. Every MISRA C document contains a set of rules, noncompliant examples, and detailed sections on the background information that contributed to the development of said rules.

Although MISRA C is not a style guide, numerous rules also promote the writing of clear, readable maintainable code. This is very beneficial, as code that is straightforward to understand is much less likely to harbor subtle bugs or undefined behavior.

In the guidance, Rule 1.3 (“There shall be no occurrence of undefined or critical unspecified behavior.”) and Directive 4.1 (“Run-time failures shall be minimized.”) are of particular importance. Many of the most serious bugs in C arise from undefined behavior, such as:

  • Buffer overruns and underruns
  • Invalid pointer direction
  • Double close
  • Data races
  • Division by zero
  • Use of uninitialized memory

Experts contend it’s important to understand the steps that lead to MISRA compliance. This includes knowing the rules and checking your code constantly. Another step involves setting baselines.

Setting baselines is crucial because embedded systems come with legacy codebases. By setting baselines, you can focus on making sure your new code is compliant.

It’s also necessary to prioritize violations based on risk. In actuality you could have hundreds or even thousands of violations in your code. Therefore it’s important to prioritize rule violations based on risk severity. Some static code analysis tools can do this for you.

MISRA is a collaborative effort among vehicle manufacturers, component suppliers, and engineering consultancies.

MISRA-C Training Course by Tonex

MISRA-C Training is designed for C programmers, engineers and managers working on safety-critical applications for automotive, medical, military, aerospace, avionics,  or other life-critical applications. MISRA-C training covers the MISRA C:2012 guidelines to ensure safe coding practices can be achieved efficiently.  For example in avionics DO-178B/C compliance, developers have to practice coding techniques to be an integrated part of the requirements traceability for assurance and safety and mitigate liability and risk.

Motor Industry Software Reliability Association (MISRA) focuses on safety covering vulnerable to C’s limitations and ways to make C safer.

Learn about MISRA C as set of guidelines for software development promoting C programming language in safety-critical embedded applications with adoption and enforcement of coding standards within multiple domains. MISRA-C was originally was released in 1998 (MISRA C:1998)/C90, and the 2004 version (MISRA-C:2004) was designed to include a host of extensions and improvements to the original version.

Who Should Attend

  • Engineering Manager
  • Project Managers
  • Software Architect
  • Software Developers
  • Software Engineers
  • V&V Engineers
  • Project Managers
  • and anyone else need to learn the details about MISRA compliance

Learning Objectives
