STMicroelectronics and YOGITECH Release Safety Design Package for STM32 Microcontrollers
(Thomson Reuters ONE) -
Flexible and affordable platform for STM32 dramatically reduces time and cost to
build systems certified to IEC 61508 functional-safety standard
Geneva, Switzerland; Pisa, Italy, February 10, 2015 - STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers across the spectrum of
electronics applications, and YOGITECH, a leader in providing functional safety
solutions, have completed development of a flexible software-design support
package that streamlines certification of safety-critical systems featuring
STM32 microcontrollers.
Begun in November 2013, the joint project 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. YOGITECH
used its patented fRMethodology white-box approach for safety analysis and
verification to create the fRSTL and the related tools suite (fRTools) that
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. These can be downloaded free of charge from st.com. On the other hand,
using the YOGITECH fRSTL_stm32 libraries provides a turnkey STL that accelerates
certification to IEC 61508 Safety Integrity Level (SIL) 2/3 while also
minimizing test costs and development risks. Either approach allows a certified
safety-critical system using a standard STM32 microcontroller, rather than a
specialized safety microcontroller with dedicated on-chip diagnostic circuitry.
"With our safety design package now ready for customers to use, the STM32
microcontroller family offers the best solution for an even wider range of
safety-critical industrial applications targeting the IEC 61508 standard," said
Michel Buffa, General Manager, Microcontroller Division, STMicroelectronics.
"While the safety manuals provide the necessary guidelines and examples of how
to use STM32 in a safety context, the YOGITECH libraries, available under
affordable license terms, will speed up and secure the SIL certification
process."
"Thanks to the partnership with STMicroelectronics, we are offering to STM32
users a standard product simply unmatched in terms of quality and convenience,"
said Silvano Motto, CEO of YOGITECH. "The fRSTL_stm32 Software Libraries are
extending our IP portfolio for safety-critical systems, confirming YOGITECH in a
lead 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 about how to use the results in the framework of other functional-
safety standards like ISO 13849, IEC 62061, IEC 61800, IEC 60730, and ISO 26262.
Further Information: STM32 Functional-Safety Package in Action:
Safety-critical industrial applications subject to IEC 61508 include systems for
controlling access to hazardous areas, systems controlling machine-operator
protection, and robot controllers. The robotics market, in particular, is
growing strongly with global shipments predicted to exceed 280,000 systems by
2017 according to the International Federation of Robotics.
ST is already working with several customers who are using the safety manuals
and YOGITECH self-test libraries to help certify functional safety of STM32-
based equipment.
"We have chosen the STM32 and fRSTL for a safety project of our customer," said
Wolfgang Pietsch, project manager at Brunel, an international business service
provider. "With the safety manual, we have a complete understanding of how the
hugely popular STM32 devices should be used in a safety context, while the use
of the fRSTL library for software diagnostics saved us a substantial amount of
time and eased the system integration."
Hans Gustavsson of Atlas Copco, a world-leading provider of drill rigs, said:
"As we are about to release an ISO13849-compliant system, we have decided to
shortcut development time by using the fRSTL libraries. The combination of the
STM32, STM32 safety manual, and fRSTL enables us to use the same platform for
almost all of our embedded projects, safety related or not, reusing code and
tools. Another benefit of a software test library is that we are better able to
design low-power systems compared with solutions only relying upon hardware."
