Klocwork IEC 61508, IEC 62304, EN 50128, and ISO 26262

Klocwork releases 2023.2 and 2023.4 are qualified to be used in safety-related software development according to the following standards:

  • IEC 61508
  • IEC 62304
  • EN 50128
  • ISO 26262

The Functional Safety standard IEC 61508 for Automotive Electric/Electronic Systems covers numerous activities and processes in the software development life cycle. ISO 26262 is a Functional Safety standard published by the International Organization for Standardization (ISO), and is targeted at road vehicle safety. The ISO 26262 standard is based heavily on the Functional Safety standard IEC 61508.

IEC 62304 is a standard that specifies life cycle requirements for the development of medical software and software within medical devices.

EN 50128 is an industry standard that specifies the requirements for development of functional safety related software in railway applications.

Developers can use the certified set of Klocwork checkers to find and fix security vulnerabilities and critical defects with confidence, knowing they have been designed, developed, tested and released in an audited and certified manner. Klocwork also provides guidance to ensure that developers use our static analysis tool in a functionally safe way that supports their own applications for certification.

While software verification tools cannot, on their own, ensure compliance with standards, for example, ISO 26262, they can aid developers looking to demonstrate process compliance. Static Code Analysis tools can either fully or partially address many of the requirements found in Part 6 of the standard. This section covers “Product Development at the Software Level” for the functional safety of road vehicles and examines correctness of software design and implementation. Klocwork's full-featured source code analysis solution helps developers find and fix security vulnerabilities and critical defects the moment they’re introduced. MISRA-C and MISRA-C++ coding standard violations can be reported automatically at the developer desktop, integration build, continuous integration build, and through the code review tool.

What do you need to know?

The Klocwork certification is documented in the Functional Safety Manual for Klocwork and related documents for 2023.2 or 2023.4. These documents describe the conditions under which the use of Klocwork supports functional safety.

Qualification pack

The qualification pack, as described in the Functional Safety Manual for Klocwork, is available from your account executive. The Qualification Pack test procedures check the requirements under normal operating conditions. Each procedure provides input data that generates a validated pass/fail report for each checker. The tool is deterministic in its execution and generates the same output results for a given set of input data parameters. To obtain the currently supported Qualification Pack for Klocwork, contact Customer Support.
