What Is MISRA®? An Overview of MISRA Coding Guidelines and Compliance

Security & Compliance

What Is MISRA®?

MISRA® is a set of C and C++ coding standards, developed by the Motor Industry Software Reliability Association (MISRA).

What's more, MISRA is a top coding standard for embedded industries, including automotive. And, MISRA ensures that C/C++ code is safe, secure, and reliable.

How to Comply with MISRA

The MISRA standard is one of the best coding standards for embedded systems. In this white paper, you'll learn best practices and tools for adopting and complying with the MISRA standard like MISRA C++:2023 and MISRA C:2025, and learn more about MISRA compliance in general.

You'll learn:

What MISRA C covers — MISRA C:1998, MISRA C:2004, MISRA C:2012, MISRA C:2023, MISRA C:2025, and MISRA C++:202x / MISRA C++:2023.
Why you should adopt MISRA C coding standards, MISRA standard, MISRA C++ standard.
How MISRA C and MISRA C++ improves new and legacy codebases.
Which MISRA checkers enforce compliance.
Static analysis tools that have 100% rule enforcement coverage for the latest, most comprehensive versions of MISRA including MISRA C++:2023 and MISRA C:2025.

Why Use Perforce Static Analysis Tools

Industry Leaders Trust Perforce Static Analysis Tools

Why Static Analysis, Code Quality Tools?

Static Analysis for C, C++, C#, Java, JavaScript, Python, Kotlin

For Safe, Secure, High-Quality Code. Faster.

Static code analysis identifies defects, vulnerabilities, and compliance issues as you code. It finds issues that are often missed by other tools and methods, such as compilers and manual code reviews. With static code analysis, you can fix coding issues earlier — lowering overall costs and enabling you to deliver a quality product on time.

Benefits of Perforce Static Analysis

Coding Standards Compliance

Ensure your software is compliant with published, well-established coding standards, such as MISRA and CERT. Or, your own internal standard.

Functional Safety Certification

Perforce static code analyzers are pre-qualified for use in safety-critical applications. This makes it easier for you to gain certification for industry standards, such as ISO 26262 and IEC 62304.

Static Application Security Test (SAST)

Build continuous code security monitoring into your development process. SAST tools help to ensure that secure coding practices are properly implemented and that vulnerabilities are removed at the earliest opportunity. Review our SAST tutorial to help you understand more about this testing and why it is important.

Code Quality Management

Automate reporting on code quality trends and compliance status to effectively measure code quality metrics and track defects.

Large-Scale Projects

Manual code reviews are time-consuming and often vulnerable to human error. Perforce’s static code analyzers quickly inspect millions of lines of source code, identifying vulnerabilities in both legacy and new code.

Developer Productivity

Perforce’s static analyzers provide developers with feedback as they code, which reduces the number of mistakes and time spent on rework – lowering overall project costs.

"Helix QAC finds issues other tools miss. We're impressed by the performance of Helix QAC. It is very accurate. It finds issues that other tools have missed."

Who Uses Static Analysis, Code Quality Tools?h

The use of code quality tools is growing within every kind of industry. It is especially important for the development of mission-critical software in:

Automotive

A typical passenger car runs more than 100 million lines of code. And, a vehicle has a wide range of software controlled sub-components – from braking systems to infotainment and communication systems. All this software requires careful review to ensure safety, reliability, and compliance.

Aerospace & Defense

Aerospace, defense, and military organizations use embedded software every day. This software is often comprised of large code bases and complex systems. And developers have an obligation to ensure that the software is safe and secure, reliable, and free of any defects.

Medical Device

The quality of software embedded in medical devices can mean the difference between life and death. Because of this, there is increasing scrutiny for both safety and security in medical device software.

Energy Technology

Energy and utilities product development teams need to ensure functional safety compliance, meet industry regulations as well as mitigate potential security vulnerabilities and coding errors.

Best Static Analyzer for Functional Safety and Standards Compliance

For over 30 years, Helix QAC has been the trusted static code analyzer for C and C++ programming languages. With its depth and accuracy of analysis, Helix QAC has been the preferred static code analyzer in tightly regulated and safety-critical industries that need to meet rigorous compliance requirements. Often, this involves verifying compliance with coding standards — such as MISRA and AUTOSAR — and functional safety standards, such as ISO 26262.

Helix QAC is certified for functional safety compliance by TÜV-SÜD, including IEC 61508, ISO 26262, EN 50128, IEC 60880, and IEC 62304. In addition, it is also certified in ISO 9001 | TickIT plus Foundation Level, which is one of the most widely adopted standards to ensure that your requirements are not only met but exceeded as well.
