Find answers to frequently asked questions about our functional safety offering.
The functional safety edition of IAR Embedded Workbench is a special product and services package containing a tool chain certified by TÜV SÜD for software development according to high integrity standards IEC 61508, and ISO 26262. For Arm and RH850 the tools are also certified for EN 50128, and for RX for 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.
High-integrity standards today frequently require you to provide extensive justification for selecting a particular development tool, unless the tool is already certified.
The functional safety versions of IAR Embedded Workbench are certified for IEC 61508 (general standard for the functional safety of electric and electronic equipment) and ISO 26262 (Automotive standard derived from IEC 61508). The tools for Arm and for RH850 are also certified for EN 50128 (European railway standard derived from IEC 61508). The tools for RX are also certified for IEC 62304 (medical device software - software lifecycle processes).
It means that the functional safety edition is certified as a qualified tool for development of safety-related applications according to the mentioned standards. The implication of this is that selection of IAR Embedded Workbench, Functional safety version as a development tool is simplified and that the user for example does not have to demonstrate language standards compliance by the own testing etc.
The certification was proceeded by a thorough assessment of how IAR Systems develop, test and support our software.
The technical certification report (accompanying the functional safety certificate) from TÜV says:
"The testing results documented in the Technical Report showed that the build tool chain of IAR Embedded Workbench for NNN as identified in chapter 2 fulfils the requirements applicable to software development tools as given by the standards listed in section 3.1." (Section 3.1 in the report lists the standards IEC 61508, ISO 26262, EN 50128, etc.)
There are no explicit references to any (A)SIL levels and this is intentional as tool users should draw their own conclusions for their specific safety functions.
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.
The functional safety editions are resting on three pillars:
The functional safety editions are available in a PC-locked version, a mobile version with dongle, a network version and a global network version. Only the standard packages are available, not the Baseline versions, Limited versions or Cortex-M version. Read more here about our licensing options.
Yes, the Functional Safety Support and Update Agreement is included for the first year after purchase.
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.
