Suite of Certification of Evidence Rolls for Wind River Cert RTOS

Wind River has announced the release of a full suite of automotive, avionics, and industrial safety certification evidence for the latest version of its VxWorks Cert Edition real-time operating system (RTOS). The RTOS for safety-critical applications is designed and developed to the highest achievable safety levels accepted by worldwide certification authorities.

VxWorks solutions have been used in more than 550 safety certification programs by more than 350 customers across industries. This most recent suite of certification evidence builds on Wind River’s 20-plus years of experience in safety certification software products, and demonstrates the company’s commitment to industry-leading safe, secure, and reliable solutions.

Like the RTOS itself, the commercial off-the-shelf (COTS) evidence is designed for reuse and portability with long-term cost-of-ownership benefits for safety-critical projects, including those specifically targeting compliance to the following standards:

  • Automotive: ISO 26262 Automotive Safety Integrity Level (ASIL) D backed by certificates issued by independently accredited certification authority TÜV SÜD
  • Avionics: DO-178C Design Assurance Level (DAL) A
  • Industrial: IEC 61508 Safety Integrity Level (SIL) 3 backed by certificates issued by independently accredited certification authority TÜV SÜD

In addition to VxWorks Cert Edition, the Wind River safety portfolio includes the VxWorks 653 integrated modular avionics (IMA) platform.

Software Speeds Safety Certification for STM32-Based Systems

STMicroelectronics has announced new free software for its STM32 microcontrollers. The functional-safety design package cuts complexity and IEC 61508 safety-certification costs for STM32-based safety critical applications. This resource is created for designers of STM32-based devices in the field of industrial controls, robots, sensors, medical, or transportation, which must be certified up to Safety Integrity Level (SIL) 2 or 3 of the recognized safety standard IEC 61508. ST’s STM32 SIL Functional-Safety Design Package simplifies system development and certification.

The SIL Functional-Safety Design Package comprises documentation and the X-CUBE-STL, a software Self-Test Library certified to IEC 61508 SIL3. The package is initially available for the STM32F0 series. ST will continue to introduce equivalent packages for all other series in the STM32 family throughout 2018 and 2019. There are currently more than 800 STM32 microcontroller variants.

ST’s STM32 SIL Functional Safety Design Package contains full documentation to support development of STM32-based embedded systems to meet IEC 61508 requirements for functional safety. The documentation comprises safety manuals that detail all applicable safety requirements, or conditions of use, with implementation guidelines to help developers certify their products to SIL 2 or SIL 3 in accordance with IEC 61508. Also included are the mandatory Failure-Modes Effects Analysis (FMEA), containing the detailed list of microcontroller failure modes and related mitigation measures, and Failure-Mode Effects and Diagnostics Analysis (FMEDA), which gives a static snapshot reporting IEC 61508 failure rates, computed at both the microcontroller and basic functions detail levels.

The software self-test library, X-CUBE-STL, is a software-based diagnostic suite for detecting random hardware failures in STM32 safety-critical core components comprising the CPU, SRAM, and Flash memory. The Diagnostic Coverage is verified by state-of-the-art ST proprietary fault injection methodology. Integrated with the familiar and proven STM32Cube workflow, it is application-independent thereby allowing use with any user application, and is delivered as compiler-agnostic object code.

TÜV Rheinland, a leading international certification institute for functional safety certification to relevant international standards, has positively assessed X-CUBE-STL-F0 according to the functional safety standard IEC 61508:2010. Detailed information of the certificate will be soon available on www.fs-products.com. Swiss-based sensor manufacturer Contrinex is the first to use ST’s Functional-Safety Design Package to certify safety products based on STM32F0 microcontrollers.

The Functional-Safety Design Package for STM32F0 microcontrollers is available from www.st.com, free of charge, subject to Non-Disclosure Agreement (NDA) with ST. Equivalent packages for other STM32 series will be introduced throughout 2018 and 2019.
