Functional safety certification

IAR Embedded Workbench for RISC-V, Functional safety edition, is a special edition of IAR Embedded Workbench for RISC-V which is certified by TÜV SÜD according to the requirements of a number of functional safety standards. The certification validates the quality of IAR Systems’ entire development processes, as well as the delivered software.

Current certified version is 3.11.

These standards are covered:

IEC 61508

  • IEC 61508 is the international umbrella standard for functional safety. The standard, and standards derived from it, is used within all kinds of industries with requirements on reliability and safety, for example process industries, the oil and gas industry, nuclear power plants, machinery, and railway control systems.

ISO 26262

  • ISO 26262 is used for automotive safety-related systems.

EN 50128 and EN 50657

  • EN 50128 and EN 50657 are European standards for safety related software in railway applications. The standards are derived from IEC 61508.

IEC 62304

  • The international standard IEC 62304 is a standard which specifies life cycle requirements for the development of medical software and software within medical devices.

ISO 25119

  • Safety requirements for tractors and machinery for agriculture and forestry. The standard is a sector-specific implementation of IEC 61508. According to ISO 25119-3 "tools and translators which are proven in use shall be applied, in order to avoid any difficulties due to translator failures which can arise during development”.

IEC 62061

  • Sector-specific (safety-related electrical control systems on machinery) standard derived from IEC 61508. It specifies the requirements for the design, integration, and validation of Safety Related Electrical Control Systems for machinery applications.

EN ISO 13849-1

  • A safety standard for machines (like IEC 62061) and focuses on electrical, electro-mechanical and mechanical (hydraulics) parts. It provides safety requirements for the principal design and integration of safety-related parts of control systems (SRP/CS), including the design of software.

IEC 61511-1

  • A sector-specific standard (process industry) derived from IEC 61508. The software requirements of this standard are limited to application software developed using FPL (fixed program language) or LVL (limited variability language).

IEC 60730-1

  • This standard applies to automatic electrical controls for use in, on, or in association with equipment for household and similar use. Requirements related to software are extracted from IEC 61508-3 and adapted to the needs of this standard.

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 edition of IAR Embedded Workbench for RISC-V is a special product and service package containing a toolchain certified by TÜV SÜD for software development according to high integrity standards IEC 61508, ISO 26262, EN 50128, EN 50657, ISO 25119, IEC 62061, EN ISO 13849-1, IEC 61511-1, IEC 60730-1 and IEC 62304. 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 26262:2018 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.

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.
