Platform med fokus på industriel sikkerhed

Green Hills Software udvider firmaets IEC 61508 platform for industriel sikkerhed (in english). 

Green Hills Software, Inc., a world leader in platform-independent embedded software solutions, has announced major enhancement to its Platform for Industrial Safety, adding support for the Green Hills Secure Virtualization Architecture and expanding the existing networking, file system and target hardware options.

Certified by TÜV to Safety Integrity Level 3 (SIL3) of the IEC 61508 safety standard, SIL3 is the highest assurance level achievable for an individual software component, such as an operating system (OS).  


The certified INTEGRITY OS technology forms the core of the Green Hills Platform for Industrial Safety, a comprehensive solution that also includes tools, secure guest OS virtualization, services, and middleware aimed at reliability-critical industrial control, transportation, railway, nuclear control and automation systems.  By utilizing Green Hills Software’s certified operating system, available middleware and support services, customers can reduce their development cost and time to certify their end products.

Green Hills Platform for Industrial Safety now offers expanded support for:
-  Secure Virtualization Architecture
-  New target processors, such as OMAP35x processors from Texas Instruments (TI) and ARM Cortex-A8
- Additional reference board support packages- Wireless supplicant support (WPA/WPA2)
- Partitionable journaling file system (PJFS)
- Enhanced Wear Leveling Flash file system support
- Expanded TCP/IP v4/v6 networking stack, security protocols, and networking applications
- Enhanced USB host stack, device stack and communications class drivers

The innovative secure partitioning capability of INTEGRITY enables software, from non safety-related through safety-critical, to be safely partitioned on a single processor. Each partition can then be certified at its appropriate Safety Integrity Level, eliminating the need for separate physical systems or to certify code beyond the required safety level.

With Green Hills’ processor-independent certification, customers have a wide range of options to choose from allowing unmatched design flexibility compared to alternative approaches, and resulting in reduced overall system complexity, product and certification cost.

Green Hills Software’s operating systems have a long history of use in electronic products requiring the highest levels of reliability and assurance. In addition to its certification to IEC 61508 SIL3, DO-178B Level A for flight-critical avionics and its use in FDA/CDRH Class II and Class III life-critical medical devices, INTEGRITY RTOS technology is the first operating system to receive security certification at assurance level EAL6+ of the Common Criteria, the highest level ever achieved for any software.

The Green Hills Software Platform for Industrial Safety delivers the following components: INTEGRITY and velOSity real-time operating systems (RTOS), with certification by TÜV to the International Electrotechnical Commission (IEC) EN 61508 standard at Safety Integrity Level 3 (SIL3); a safety manual; SIL3 certification certificate and report; MULTI Confidence-from-Use report (optional).

<b>About IEC 61508</b>

IEC 61508 is an international standard for the functional safety of electrical, electronic, programmable electronic (E/E/PE), and safety-related systems and applies to these systems regardless of their applications. IEC 61508 is the basis for a published nuclear sector standard (IEC 61513).

It is also currently being used as the basis for developing other sector standards (e.g. machinery, process – IEC 61511), along with standards in Railway (EN 50128/CENELEC) and automotive (ISO 26262, draft). It is therefore influencing the development of E/E/PE safety-related systems and products across all industry sectors, where safety and reliability are paramount.

Meeting the well defined, stringent IEC 61508 requirements involves supporting a systematic development process, emphasizing requirements traceability, criticality analysis and validation. The SIL3 rating is considered the highest level of risk reduction achievable using a single processor.
