Nuremberg, Germany —March 2, 2010 — Embedded World 2010, Hall 10 Booth 10-319 — Green Hills Software, Inc., the largest independent vendor of embedded software solutions, today announced that its Platform for Industrial Safety has expanded its safety certification support by achieving a SWSIL 4 certification for its INTEGRITY® RTOS (real-time operating system) against the stringent CENELEC EN 50128 standard, which targets software for railway control and protection systems. Certified by both TÜV and Exida, INTEGRITY has received the highest assurance level possible against this safety standard for an individual software component, such as an operating system.

The certified INTEGRITY operating system forms the core of the Green Hills Platform for Industrial Safety, a comprehensive solution comprised of tools, operating system, secure guest OS virtualization, services, and middleware aimed at reliability-critical industrial control, transportation, railway, nuclear control and automation systems. By incorporating the Green Hills certified operating system into safety-critical systems, along with available middleware and support services from Green Hills, customers significantly reduce their risks, development costs, and time to certify their end products.

"As one of the largest technical service providers in Germany and a leader in functional safety certification services, TÜV NORD SysTec sees a growing demand for functional safety requirements in many new control system design starts," commented Gerhard Rieger, Dipl.-Ing, TÜV NORD SysTec. "By achieving the EN 50128 safety certification for its INTEGRITY operating system, Green Hills is positioned to support this growing demand with safety-proven solutions for its end customers."

By adopting Green Hills Software’s safety-certified INTEGRITY RTOS, developers are able to safely partition independent applications of multiple levels of safety criticality concurrently on a single processor and platform. The INTEGRITY safety-proven architecture enables applications to be partitioned in a way to ensure that an error or failure in one application cannot impact or compromise another application.

"This new certification gives Green Hills customers who are building railway and transportation systems a proven safety platform to base their software applications on," commented Rainer Faller, managing director, Exida GmbH. "Green Hills has always been a leader in delivering safe, secure solutions to its customers and its Platform for Industrial Safety is a leading example."

"The growth worldwide in new railway and transportation design projects is significant. And with this comes significant growth in software complexity and code size for these new designs," commented Dan Mender, vice president business development, Green Hills Software. "With the addition of the EN 50128 safety certification for railway/transportation, the Green Hills Platform for Industrial Safety, along with its large contingent of partners in this market, provides our end customers with the shortest time-to-market, least risk approach for development and delivery of these critical next-generation systems."

The Green Hills Platform for Industrial Safety delivers the following: INTEGRITY real-time operating system with certification by TÜV and Exida to the International Electrotechnical Commission IEC 61508 and CENELEC EN 50128 standards at Safety Integrity Level 3 (SIL 3) and Safety Integrity Level 4 (SWSIL 4) respectively; a safety manual; IEC 61508 SIL 3 and EN 50128 SWSIL 4 certificates and reports; a MULTI Confidence-from-Use report (optional), along with optional middleware and a broad group of industry leading partners targeting the industrial and functional safety marketplace.

About EN50128
The railway industry requirements are defined by CENELEC, the European Committee for Electrotechnical Standardization. The standard EN 50128 "software for railway control and protection systems" represents the railway application-specific interpretation of the international standard series - IEC 61508 (functional safety of electrical/ electronic/programmable electronic safety-related systems). The EN 50128 standard describes software safety integrity levels and identifies requirements for personnel and their responsibilities, lifecycle issues and documentation. Meeting the well-defined, stringent EN 50128 requirements involves supporting a systematic development process, emphasizing requirements traceability, criticality analysis and validation.
