STMicroelectronics’ EMIF02-01OABRY is a highly integrated solution designed to suppress electromagnetic interference (EMI) noise in automotive applications employing BroadR-Reach® interfaces.
BroadR-Reach® is an automotive Ethernet standard defined by the OPEN Alliance that allows multiple in-vehicle applications such as Advanced Driver Assistance and infotainment systems to access information simultaneously over a single unshielded twisted pair cable, reducing cabling cost and weight as cars become ever more connected. BroadR-Reach is a registered trademark of Broadcom Corporation.
The EMIF02-01OABRY EMI-suppressing low-pass filter includes 15kV ISO 10605 surge protection and is AEC-Q101 qualified.
MOST offers numerous dedicated communication channels for the transmission of multimedia content in various formats and data rates. In addition to these dedicated channels, there is the Asynchronous Channel, over which MOST Ethernet offers a service referring to Ethernet, the well-known standard in computer networking. This service allows for a TCP/IP or UDP/IP architecture on top, which brings a vast range of applications into the automotive domain. The usage of these applications not only requires a suitable protocol architecture, but further requirements concerning bandwidth or communication latency have to be fulfilled.

SymTA/S 3.7 introduces new Ethernet timing design and verification features including the modeling and analysis of dynamic data chains and data dependent dynamic Ethernet frame packing as well as faster system distribution analysis compared to previous versions.
SymTA/S 3.7 also incorporates new general modeling and timing analysis features – Gantt-Filter, APIs and improved AUTOSAR 4.x multicore import.
The OPEN Alliance (One-Pair EtherNet) Special Interest Group (SIG), a non-profit industry alliance established to drive wide scale adoption of Ethernet-based automotive connectivity, announced broad availability of its automotive Ethernet specifications.
One Twisted Pair Ethernet, also known as Open Alliance BroadR-Reach (OABR), delivers high-performance bandwidth of 100 megabits per second (Mbps) per port while dramatically reducing connectivity costs and cabling weight.
A growing number of automotive OEMs have deployed OABR technology to serve as a single-network platform, with the inherent security features, scalability and flexibility to be used in a broad segment of in-vehicle applications. The formation of the IEEE 802.3 task force to advance One Twisted Pair 100 Mbps Ethernet is expected to further drive wide scale adoption of the technology.
To meet growing bandwidth and communication requirements for cars, more designers are tapping into automotive Ethernet interfaces. For automotive Ethernet, it’s critical to verify both the intellectual property (IP) block-level components and its sub-features and the system-level integration and interoperability implications. This article takes a look at how verification IP can facilitate development of the rich features and functions that consumers now expect in their cars.

Synopsys Expands VDK for Renesas RH850 Ethernet AVB and CAN-FD for Automotive System Software Development
Synopsys, Inc. (Nasdaq: SNPS) announced the expansion of its Virtualizer™ Development Kit for Renesas’ RH850 MCU Family to include support for Ethernet AVB and CAN-FD automotive network peripherals.
The Synopsys VDK for Renesas RH850 MCU is a software development kit that uses RH850 virtual prototypes as a target with software debug and analysis tools. It enables automotive engineers designing RH850-based electronic control units (ECUs) to start software development, integration and test months before hardware is available, resulting in higher product quality and reduced development cost.
Current projections indicate that by 2020, more than 120 million cars will be equipped with Ethernet connectivity, with the premium segment connecting up to 35 systems with Ethernet, and in mid-range vehicles, between 8-20 systems. Ethernet is well-qualified to serve as the bus of choice for next-gen vehicles because it delivers the necessary capacity, performance and versatility unavailable from CAN bus, FlexRay, MOST, J1850/1939 and other semi-proprietary protocols. This article will show how Ethernet can meet the requirements of tomorrow’s vehicles and how it will shape the evolution of automotive networks over the next 5-10 years.
Mentor Graphics (NASDAQ: MENT) announced the availability of Automotive Ethernet support in the Volcano™ VSA™ product for network design of both AUTOSAR-based and non-AUTOSAR electronic control units (ECUs).
Increasingly, in areas in which high bandwidth and reliable performance are essential, Ethernet is being used. These include advanced driver assistance systems (ADAS), vehicle network backbones, audio video bridging (AVB) systems, and diagnostic communication over Internet Protocol (DoIP).
The Mentor® Volcano VSA tool addresses the network-wide timing analysis challenges where a mixture of CAN, FlexRay, and Ethernet-based network busses co-exist. The AUTOSAR standard supports timing definition for all elements in a mixed-topology network. The Volcano VSA tool addresses the challenge of accounting for the many different timing paths.
At International CES 2015 Broadcom Corporation announced its next-generation BroadR-Reach automotive Ethernet chip, BCM89811 PHY, optimized for use in low-power automotive applications.
Delivering 100 megabit per second (Mbps) performance over a single, unshielded twisted pair wire, the highly integrated chip combines the functionality of multiple discrete devices in an ultra-small package (6×6 mm).
Ethernet in the Connected Car
While Ethernet has long been used as an IT network technology, its application in the connected car is an undeniably growing trend. The low power features of Broadcom’s new BCM89811 physical layer transceiver (PHY) enable new use cases for automotive Ethernet beyond infotainment and Advanced Driver Assistance Systems (ADAS) into telematics, shark fin antennas, instrumentation clusters, head unit and center stack module applications.
