Functional safety

Functional safety is one of the most important features in many embedded systems today. High-integrity standards frequently require you to provide extensive justification for selecting a particular development tool, unless the tool is already certified. The proof of compliance for the tools increases cost and time of development.

To solve this problem, we provide safety-certified editions of our development tools.

Certified development tools

The functional safety editions of our tools are certified by TÜV SÜD according to the requirements of IEC 61508, the international umbrella standard for functional safety, as well as ISO 26262, which is used for automotive safety-related systems. In addition, the certification covers the international standards IEC 62304 for medical software, and the European railway standards EN 50128 and EN 50657. For Arm and RISC-V, the tools also cover IEC 60730, ISO 13849, IEC 62061, IEC 61511 and ISO 25119.

Integrated code analysis

Code analysis and functional safety - a great match!

Many industry standards require the use of code analysis tools. In this article, you will learn how you can use our code analysis tools when developing safety-certified applications.

Support and Update Agreement

With the Functional Safety editions of our products, there is a special Functional Safety Support and Update Agreement.

Details

The Functional Safety Support and Update Agreement (SUA) is a special version of our standard SUA. It contains:

  • Guaranteed support for the sold version for the longevity of the contract
  • Prioritized technical support
  • Validated service packs containing only fixes to known issues and information about issues
  • Regular reports of known deviations and problems

IAR Systems supports a specific certified version as long as there are users with active support and update agreement on that version.

Functional safety FAQ

Find answers to frequently asked questions about our functional safety offering.

What is the functional safety edition of IAR Embedded Workbench?

The functional safety editions of IAR Embedded Workbench and IAR Build Tools for Linux are special product and services packages containing a toolchain certified by TÜV SÜD for software development according to high integrity standards IEC 61508, ISO 26262, EN 50128, EN 50657 and IEC 62304. For Arm and RISC-V, the certification also covers IEC 60730, ISO 13849, IEC 62061, IEC 61511 and ISO 25119. A special support and update agreement gives you support and updates for the frozen version you are using for the longevity of the agreement. The certification is done for a specific version of the tool chain. Not every feature release will be certified.

Why would I buy the certified version of IAR Embedded Workbench?

High-integrity standards today frequently require you to provide extensive justification for selecting a particular development tool, unless the tool is already certified.

What does the certification mean?

It means that the functional safety edition is certified as a qualified tool for development of safety-related applications according to the mentioned standards. By selecting IAR Embedded Workbench Functional safety edition as a development tool, you do not have to evaluate the tool development process yourself and also not demonstrate language standards compliance by your own testing. This has already been taken care of by TÜV SÜD.

The certification was proceeded by a thorough assessment of how IAR Systems develop, test and support its software.

Up to which (A)SIL level is the functional safety edition of IAR Embedded Workbench certified?

The technical certification report from TÜV says:

"The build tool chain of EWNNFS is suitable to be used in safety-related development projects according to ISO 26262:2011 for any ASIL level. The requirements of the "Validation of the software tool in accordance with [ISO26262-8, Chapter] 11.4.9" and "Evaluation of the tool development process in accordance with [ISO26262-8, Chapter] 11.4.8" are fulfilled."

Further it says:

“The build tool chain of EWARMFS classified as T3 off-line tool according to IEC 61508-4:2010, is suitable to be used in safety-related development projects according to IEC 61508:2010 for any SIL level.”

There are no explicit references to any specific (A)SIL levels and this is intentional as tool users should draw their own conclusions for their specific safety functions.

If my particular standard is not covered, can I still benefit from using the certified version?

Yes, many sector specific standards are derived from IEC61508 and thus tools qualification requirements are similar. For some standards additional information might be needed and we are in those cases happy to provide such information on a case-by-case basis. Further, the services in the special Support and Update Agreement (See below) are just as valuable for any project where quality and reliability of the end product is at the forefront.

How does the functional safety edition of the product differ from the standard product?

The functional safety editions are resting on three pillars:

  • A specific certified version of IAR Embedded Workbench where no new features will be added. Updates will only consist of corrections of erratical behavior and notifications of issues to be aware of.
  • A special Support and Update Agreement; see below for more information.
  • Certification documentation, including the certificate and a report to the certificate. The documentation package also includes a Safety Guide detailing the use of the tool chain in a functional safety context.

What's included in the special Functional Safety Support and Update Agreement?

  • Support and updates for the specific certified version. This includes specially validated service releases containing only fixes to known issues and information about issues. IAR Systems supports a specific certified version as long as there are users with active support and update agreement on that version.
  • Prioritized support
  • Extra documentation needed for safety related development

Is the special support services included in the price?

Yes, the Functional Safety Support and Update Agreement is included for the first year after purchase.

What features of the tool chain are certified?

The full build tool chain and all of its features are covered by the certification. This include, but is not limited to, features like optimizations, language extensions, intrinsic functions etc. However, safety-related standards often place constraints or require extra justification to use such features. The restrictions or the amount of justification that might be needed differ between standards and the safety integrity level for the project. The usage of such features are covered in the Safety Guide.
