Multi-Gbit Ethernet compliance test meets IEEE 802.3ch

Thu, Feb 04, 2021

Believed to be the first multi automotive Gbit Ethernet compliance tester, the TekExpress has been released by Tektronix.

It confirms the integrity of faster signals to achieve higher data transfer rates and enable advanced technologies to meet the requirements of complex automotive designs. Newer automotive technologies, such as autonomous driving, 5G and connected cars, require a vast amount of data necessary and must be tested to ensure reliable transfers between a vehicle’s electronic sub-systems.

The automated compliance test application allows for quick, accurate and reliable validation and debugging for multi-Gbit Ethernet chipsets and electronic control units (ECUs) to meet physical media attachment (PMA) transmitter measurement requirements for up to 10Gbits per second.

The Tektronix TekExpress multi-Gbit automotive Ethernet compliance test solution is fully automated and meets the current version of the IEEE 802.3ch MultiGBASE-T1 specification.

“Multi-gigabit Ethernet uses PAM4 modulation to achieve high data rates and reliability, pushing the boundaries of signal integrity and requiring higher performance measurements for compliance, debugging and validation. Debug tools like DPOJET and PAM4 analysis also allow for quick identification of the root cause of a failure,” said Raajit Lall, general manager of Market Solutions at Tektronix.

The Tektronix TekExpress multi-Gbit automotive Ethernet compliance test solution is part of its family of automated compliance solutions for automotive Ethernet, and it works seamlessly with Tektronix oscilloscopes. It uses the TekExpress automation framework which means that engineers do not have to learn a new software interface.

This new application enhances Tektronix’s in-vehicle network offering of 10BASE-T1S, 100-BASE-T1 and 1000BASE-T1 compliance testing applications for automotive Ethernet standards.

The Tektronix IEEE 802.3ch Multi-Gigabit Ethernet automated compliance application is now available globally for 10G/5G/2.5GBASE-T1 automotive Ethernet PMA transmitter compliance testing on DPO70000 SX/DX series oscilloscopes.

Tektronix is an active participant in the Open Alliance, developing in-vehicle network test specifications and methodologies for reliable, cost-effective testing.

The company is headquartered in Beaverton, Oregon, USA. It specialises in test, measurement and monitoring solutions.

Solid state lidar has range of 150m+, says RoboSense

Thu, Jan 14, 2021

At CES 2021, RoboSense announced the standard operating procedure (SOP) version of its automotive-grade, MEMS solid-state lidar, RS-LiDAR-M1.

Features include a ranging capability of more than 150m for 10 per cent reflectivity targets and a range of up to 200m for detecting vehicle objects. The average resolution of M1 is 0.2 x 0.2 degrees (horizontally and vertically) with a wide field of view of 120 x 25 degrees (horizontally and vertically) to create a high resolution of 0.75M pixel points per second.

The RS-LiDAR-M1 has reduced the minimum detection distance to less than 0.5m by upgrading the optical system design and signal processing system. RoboSense has innovated the signal processing algorithms and optical system design, enabling the M1 to distinguish laser emission signals from ambient lights, without interference from strong sunlight.

M1 filters laser pulses from other lidars to prevent crosstalk. The SOP version is claimed to be the world’s thinnest automotive lidar, measuring 108mm in depth, 110mm wide and 45mm high for ease of integration into the vehicle body.

Power consumption is less than 15W. Supporting functions include over-the-air firmware updates, blockage detection, smart cleaning, smart heating, performance detection, power management and network management.

RoboSense has adopted VDA6.3 as the basis of project management and control, implemented IATF16949 quality management system and the ISO26262 standard, and has integrated ISO16750 and other automotive-grade reliability specifications, to carry out a series of verification tests on M1. Tests include random mechanical vibration, mechanical shock, splash water, stone impact, high and low temperature storage and operation, solar radiation, EMC, chemical corrosion and salt spray. The cumulative test time of all M1 test samples has exceeded 300,000 hours, reports the company. The longest-running prototype has been in continuous operation for more than 700 days, and the total road test mileage has exceeded 200,000km.

Founded in 2014, RoboSense provides smart lidar sensor systems, incorporating lidar sensors, artificial intelligence (AI) algorithms and IC chipsets, that transform conventional 3D lidar sensors to full data analysis and comprehension systems.

Automotive ASIC integrates AI to monitor the driver

Tue, Jan 05, 2021

Believed to be the world’s first dedicated driver monitoring ASIC, the OAX8000 has an integrated artificial intelligence (AI) neural processing unit, an image signal processor and a DDR3 memory.

The ASIC by OmniVision Technologies is optimised for entry level, standalone driver monitoring systems (DMS). The OAX8000 uses a stacked-die architecture, making it the industry’s only DMS processor with on-chip DDR3 SDRAM, claims the company. Memory capacity is 1Gbyte. It is also believed to be the only dedicated DMS processor to integrate a neural processing unit (NPU) and image signal processor (ISP), which provides dedicated processing speeds up to 1.1 trillion operations per second to allow for eye gaze and eye tracking algorithms. There is also 1k multiply-accumulator MAC (units) of convolutional neural network (CNN) acceleration, which, with the integrated SDRAM, enable the low power consumption. Combined with the OmniVision automotive image sensor, it consumes just 1W in typical conditions. The level of integration also reduces the board area for the engine control unit (ECU), adds OmniVision Technologies.

From 2022, all new cars in the EU will be required to have a DMS camera.

“Most DMS processors on the market today are not dedicated to this application, requiring added circuitry to perform other system functions that consumes more power, occupies more board space and doesn’t allow room for on-chip SDRAM,” said Brian Pluckebaum, automotive product marketing manager at OmniVision. industry’s most optimized solution.”

The OAX8000’s on-chip NPU is supported by the TensorFlow, Caffe, MXNet and ONNX tool chains. The ASIC embeds quad Arm Cortex A5 CPU cores with Neon technology for accelerated video encoding/decoding and on-chip video analytics algorithms, as well as hardware for image processing, video encoding and RGB/IR processing. The high dynamic range (HDR) processing capability allows the ASIC to accept input from RBG/IR image sensors and to support high quality output, for videos taken during the day or at night, in conditions with widely contrasting bright and dark images. The integrated video encoder accepts up to 5Mpixel captures from OmniVision’s automotive image sensors, and outputs up to 2k resolution video at 30 frames per second (fps).

Boot-up time for the OAX8000 is significantly faster than its nearest competitor, claims OmniVision. The rapid start up eliminates the delay between ignition and activation of the DMS camera and the ASIC also supports secure boot features for cybersecurity.

The ASIC can also be used in processing vehicle occupant detection algorithms, such as distinguishing a baby from a grocery bag, and providing alerts when objects are left behind in the vehicle. Other uses are in automotive video security systems to perform functions such as FaceID, as well as preset driver comfort settings (e.g. seat position) that are activated when the DMS scans the driver’s face.

Samples of the new OAX8000 ASIC are available now in a BGA196 package. It is AEC-Q100 Grade 2 certified for automotive applications.
