Dev Tools Extend Transportation Safety Standards Coverage

IAR Systems has updated the functional safety editions of the leading embedded development toolchain IAR Embedded Workbench with new functional safety certificates. The new certificates add the standard EN 50657:2017 “Railways Applications – Rolling stock applications – Software on Board Rolling Stock” as well as a later revision of the “Road vehicles – Functional safety” standard called ISO 26262:2018.

Functional safety is one of the most important features in many embedded systems and companies must consider development tools as an integral part of the system certification, says IAR Systems. The proof of compliance for the tools increases cost and time of development. To solve this problem, IAR Systems provides certified versions of the complete compiler and debugger toolchain IAR Embedded Workbench for Arm, Renesas RX, Renesas RL78 and Renesas RH850.

The build chains of IAR Embedded Workbench for Arm, RX, RL78 and RH850 have been tested and approved according to the requirements on support tools put forth in the international umbrella standard for functional safety IEC 61508, the standard for automotive safety-related systems ISO 26262, and the the European railway standard EN 50128 and EN 50657. For Arm, RX and RL78, the certification also covers IEC 62304, defining the life cycle requirements for medical device software.

The quality assurance measures applied by IAR Systems and the included Safety Manual allow application developers to use the tools in safety-related software development for each Safety Integrity Level (SIL) according to IEC 61508 and each Automotive Safety Integrity Level (ASIL) of ISO 26262. IAR Embedded Workbench is certified by TÜV SÜD.

IAR Embedded Workbench provides a complete IDE including the IAR C/C++ Compiler and the C-SPY Debugger. The code analysis tools C-RUN® and C-STAT® add static and runtime analysis, enabling complete code control through the entire development cycle. Thanks to the complete integration of the tools in the IAR Embedded Workbench IDE, developers get up and running quickly with the analysis.

IAR Systems also offers a Functional Safety Support and Update Agreement with guaranteed support for the sold version for the longevity of the contract. In addition to prioritized technical support, the agreement includes access to validated service packs and regular reports of known deviations and problems.

Hypervisor Achieves Compliance to New Version of ISO 26262

OpenSynergy has received the certificate from TÜV SÜD confirming the compliance of OpenSynergy’s COQOS Hypervisor to ISO 26262:2018 ASIL-B. COQOS Hypervisor is a Type-1 hypervisor for the ARMv8 architecture developed specifically to support automotive use-cases such as cockpit and domain controllers. OpenSynergy specializes in embedded automotive software and its hypervisor technology has been in mass production since 2014.

The COQOS Hypervisor is a Type-1 hypervisor for automotive applications. It allows customers to build highly compartmentalized systems that can be tailored to their specific requirements. The COQOS Hypervisor has been developed for the ARMv8 architecture, supports many automotive SoC’s and takes full advantage of hardware virtualization. Current series development with COQOS Hypervisor includes cockpit controllers –integrating infotainment and a digital instrument cluster–, infotainment systems, rear-seat entertainment, connectivity devices and gateways.
Some of these use-cases include safety-relevant functionalities, such as displaying tell-tales on the instrument cluster. In these cases, the hypervisor must provide freedom from interference between the safety and non-safety virtual machines. This is why OpenSynergy has developed COQOS Hypervisor as a Safety Element out of Context (SEooC) according to ISO 26262 ASIL-B using safety requirements based on real automotive use-cases.

The examination and certification by TÜV SÜD Rail GmbH has now confirmed that COQOS Hypervisor complies to the new version of the ISO 26262 standard (ISO 26262:2018) at the ASIL-B level. The new version of the ISO 26262 standard has additional expectations, e.g. on the management of the security of the product. COQOS Hypervisor is the first hypervisor that has been certified according to this new version.

COQOS Hypervisor is part of OpenSynergy’s package COQOS Hypervisor SDK. The SDK includes pre- integrated guest operating systems (such as Linux and Android), standards-based sharing of devices between the virtual machines and pre-configured automotive use-cases. For the cockpit controller use-case, COQOS Hypervisor SDK includes OpenSynergy’s Safe Instrument Cluster technology ensuring that tell-tales are rendered correctly when using a Linux-based instrument cluster. In December 2018, TÜV SÜD already had confirmed that this architecture satisfies ISO 26262 ASIL-B.

Siemens Acquires Austemper Design Systems

Siemens has entered into an agreement to acquire Austin, Texas-based Austemper Design Systems, a startup software company that offers analysis, auto-correction and simulation technology. This technology allows customers to test and harden IC designs for functional safety in applications such as automotive, industrial and aerospace systems. These are systems where functional safety and high reliability are mandatory for compliance to safety standards like ISO 26262.

ICs in these applications require three types of functional safety verification: for systemic faults, malicious faults and random hardware faults. Mentor’s existing Questa software (shown) is a leading technology for functional verification of systemic faults and provides solutions for verification of malicious faults for IC security. The software technology from Austemper adds state-of-the-art safety analysis, auto-correction and fault simulation technology to address random hardware faults. This is expected to complement Mentor’s existing functional safety offerings including its Tessent product suite and Veloce platform.

Design teams at leading semiconductor and IP companies use Austemper’s innovative technology to analyze the registered-transfer level (RTL) code versions of their designs for faults and vulnerabilities. It can automatically correct and harden vulnerable areas, subsequently performing fault simulation to ensure the design is hardened and no longer susceptible to errors. Moreover, the Austemper technology performs simulation at orders of magnitude faster than competing solutions.

Siemens will integrate Austemper’s technology into Mentor’s IC verification portfolio as part of Siemens’ larger digitalization strategy, leveraging Siemens’ world-wide sales channel to make this functional safety solution available to companies developing digital twins of safety-critical systems at the heart of autonomous vehicles, smart cities and industrial equipment in Factory 4.0.
