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.

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 Announces Automotive Ethernet support for Its AUTOSAR Design Solutions

mentor logoMentor 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.

UNH-IOL Lab Expands Interoperability Testing and Support for 40G/100G, Including Automotive Ethernet

unh-iol 12-9-14 west-pe-api.azurewebsites.netThe University of New Hampshire InterOperability Laboratory (UNH-IOL), an independent provider of broad-based networking testing and standards conformance services, announced expanded interoperability testing and support for 40 and 100 Gigabit Ethernet (40G/100G) including automotive Ethernet, 25Gb/s serial-lanes, Power over Ethernet (PoE), and Backplane. This activity is taking place within several of the UNH-IOL’s consortia and collaborative testing programs.

With heightened demand for 40G products in 2014, the UNH-IOL 40 and 100 Gigabit Ethernet Consortium has seen a significant increase in participation from members seeking 40G interoperability which, along with IEEE standards-compliance, is a helpful market differentiator.

NXP Semiconductors N.V. and TTTech have signed a Memorandum of Understanding to jointly develop automotive Ethernet switch solutions supporting OPEN Alliance BroadR-Reach® Ethernet PHY technology. The switch chip will be specifically designed for the automotive market, but will also be suitable for various demanding industrial real-time applications.

NXP has been working with industry partners to establish BroadR-Reach as an open, de facto standard for in-vehicle Ethernet. Under the agreement, TTTech will provide the switch IP while NXP implements the IP into Ethernet switch solutions with integrated PHY.

TTTech has developed an automotive Ethernet switch IP solution based on its Ethernet experience in several vertical markets.

Comparing Ethernet and SerDes in ADAS applications

By Dave Lewis, Automotive Analog Marketing Manager, Texas Instruments

Abstract

Single-pair Ethernet is currently being deployed in automobiles over unshielded twisted pair (UTP) cable. Ethernet shows great promise as an in-vehicle networking technology for the connected car due to its ubiquity, tools, modularity, and IP support.

Although some infotainment display and camera-based advanced driver assistance system (ADAS) applications have introduced Ethernet to prove the technology, serializer/deserializer (SerDes) architectures (sometimes incorrectly called LVDS) typically are simpler, offer higher video quality, and are less expensive in these systems.

Let’s compare these two technologies in detail using a four-camera surround view application as an example.
