STMicroelectronics has collaborated with a leading provider of functional safety solutions, YOGITECH to develop a flexible software-design support package that streamlines certification of safety-critical systems featuring STM32 microcontrollers.

The joint project, which began in November 2013, has produced a set of STM32 safety manuals to assist application design as well as Software Test Libraries (fRSTL) certified according to the IEC61508:2010 functional-safety standard. Using its patented fRMethodology white-box approach for safety analysis and verification to create the fRSTL and the related tools suite (fRTools), YOGITECH ensures superior and proven diagnostic coverage compared to conventional black-box testing.

Customers can choose to develop their own STL, referring to the STM32 safety manuals, or alternatively, download free of charge from st.com. Users can however, take advantage of the YOGITECH fRSTL_stm32 libraries that provide a turnkey STL accelerating certification to IEC 61508 Safety Integrity Level (SIL) 2/3 while also minimising test costs and development risks. Both approaches allow a certified safety-critical system using a standard STM32 microcontroller.

Michel Buffa, General Manager, Microcontroller Division, STMicroelectronics explains that the STM32 microcontroller family offers the best solution for an even wider range of safety-critical industrial applications targeting the IEC 61508 standard. While the safety manuals provide the necessary guidelines on using STM32 in a safety context, the YOGITECH libraries, available under affordable license terms, will speed up and secure the SIL certification process.

YOGITECH CEO Silvano Motto commented that their partnership with STMicroelectronics enables them to offer a standard product simply unmatched in terms of quality and convenience, to STM32 users. He adds that the fRSTL_stm32 Software Libraries are extending their IP portfolio for safety-critical systems, confirming YOGITECH’s leadership position as a supplier of solutions in accordance with the IEC61508 standard and related derivatives applied to integrated circuits.

The manuals and libraries cover STM32 F0, F1, F2, F3, F4, and L1 series, giving engineers a choice of over 500 devices offering high performance and rich features for safety-critical applications. Support for other STM32 series will be added in the near future.

The fRSTL software libraries are certified by TÜV Rheinland according to the IEC61508:2010 functional safety standard for systematic capability (SC3) and a Diagnostic Coverage according to the direct-current fault model that can be used in applications up to and including SIL2 (HW Fault Tolerance-HFT of 0) and SIL3 (HFT of 1). The Safety Manuals also give indications on using the results in the framework of other functional safety standards such as ISO 13849, IEC 62061, IEC 61800, IEC 60730, and ISO 26262.
