The certification of safety end-products requires a compiler toolchain used in development to be qualified according to appropriate functional safety standards. The process of qualifying these tools known as ‘Tool Qualification’ or ‘Tool Validation’ can be time-consuming and expensive process. Moreover, it doesn’t offer any differentiation to the end-product. While end-users have to be responsible for the overall tool qualification process, vendors of development tools can make this process much easier by offering tools that are qualified to appropriate safety standards.
Arm Compiler for Functional Safety is a qualified C/C++ toolchain that has been assessed by safety-accredited certification body, TÜV SÜD. The qualified toolchain is suitable for developing embedded software for safety markets including automotive, industrial, medical, railways and aviation.
With a TÜV certificate and a comprehensive Qualification Kit, Arm Compiler for Functional Safety greatly simplifies the overall ‘Tool Qualification’ process allowing end-users to focus on their end-product development.
Arm Compiler for Functional Safety is qualified for developing software that meets the highest level of safety integrity for the following standards:
For other safety standards, many of which have been derived from IEC 61508, the Qualification Kit provides the key information end-users need to perform ‘Tool Validation’.
Each release of Arm Compiler for Functional Safety goes through extensive testing and a qualification process. The qualification covers the toolchain binaries:
Standard C/C++ libraries are included in the product but excluded from the qualification. An optional Certified C Library is available to license separately with specific versions of Arm Compiler for Functional Safety.
Every Arm Compiler for Functional Safety release has a Certificate from TÜV SÜD. The Certificate is accompanied by a TÜV assessment report which provides assurance that the processes used to develop the toolchain are in accordance with the safety standards stated in the Certificate.
The Qualification Kit provides vital safety information about the toolchain operation, recommended usage, and diagnostic capabilities.
Safety systems are getting increasingly complex and need to be reliable, highly predictable, even as the product ages, and finally be consistent throughout its lifetime. To achieve this, safety developers require a toolchain that is stable and has minimal change which reduces risk and overhead costs due to re-validation.
Arm Compiler for Functional Safety is derived from, but different to, the standard Arm Compiler product. Each safety branch is hardened by defining a safety boundary and stable feature set prior to qualification.
Each safety branch is maintained for 5 years from market entry and receives regular maintenance updates for safety-critical defects. The updates are qualified and accompanied by a TÜV Certificate and an updated Qualification Kit. Along with Arm's expert technical support, this provides customers with confidence that their projects can be supported for many years.
For customers who need extra assurance and peace of mind, Arm offers bespoke premium support and maintenance services that can be tailored to their needs. For more information, get in touch with us.
The next-generation safety toolchain, Arm Compiler for Embedded FuSa 6.16LTS will be available in Q3 2021.
Arm Compiler for Embedded FuSa 6.16LTS is the successor of the current Arm Compiler 6.6 for Functional Safety toolchain and it brings:
Arm Compiler for Embedded FuSa 6.16LTS is recommended for new safety projects. Prospective customers can start development with the standard Arm Compiler 6.16 toolchain, then easily migrate to 6.16LTS once it is available.
Arm recommends the use of Arm Development Studio Gold Edition or Keil MDK Professional licenses, since these will enable the use of both the standard Arm Compiler 6.16 and the 6.16LTS (once available).
Customers using Arm Compiler 6.6 for Functional Safety may want to migrate to 6.16LTS, provided the safety project is not in its final stage. Migration guidance can be found in the Qualification Kit and user documentation of the safety toolchain or feel free to get in touch with our support team for expert guidance.

For faster safety development and go-to-market, the Certified C Library can be licensed separately in addition to the Arm Compiler for Functional Safety. The library is a subset of the standard C library comprising of approximately 200 functions that have been specifically implemented and optimized for use in safety development.
The Certified C Library comes with its own certificate from TÜV SÜD and supports the same functional safety standards as the Arm Compiler for Functional Safety. It is also accompanied with its own Qualification Kit which comprises of the Safety Manual and Defect Report.
Note: The Certified C Library is compatible with specific versions of Arm Compiler for Functional Safety. Please ensure to check for compatibility.
