How Verification IP Facilitates Creation of Automotive Ethernet-Based Applications

March 12, 2015  by  

By Herbert Rivera-Sanchez, Cadence Design Systems


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.

High Power Automotive LED Headlamps Need HB LED Driver ICs

March 12, 2015  by  

By Jeff Gruetter,Sr. Product Marketing Engineer, Power Products, Linear Technology


Arguably, one of the most demanding applications for driving HB LEDs is found in automotive headlamp applications, as they must deliver high power (typically between 50W to 75W) and fit into thermal- and space-constrained enclosures. Power conversion solutions must be highly efficient, robust in features and reliability while being very compact and cost effective. Linear Technology is continually redefining its family of LED drivers to meet these challenges with HB LED driver ICs such as the LT3791.

Trends in Auto Safety – Eliminating the Blind Spot

February 19, 2015  by  


One of the most interesting and fastest growing automobile safety applications is Advanced Driver Assistance Systems (ADAS). These systems use a combination of sensors, cameras and displays to provide greater driver visibility and also react to dangerous situations when a driver doesn’t. The ability to deliver reliable, easy to integrate and cost effective video solutions will be key enablers of the next generation of ADAS features, which are increasing driver safety and ultimately consumer demand for new vehicles. Sophisticated SoCs introduced reliability issues, booting up too slowly to provide timely rear camera video to the driver immediately after initial ignition of the vehicle.

The Art of Automotive Application Design: Performance Optimizations for a 32bit Automotive Microcontroller

February 16, 2015  by  


In the world of automotive microcontrollers, whatever the design aspect, the goal is to get the maximum performance respecting application requirements at a minimum price. The improvement process is driven by cost aspects, but equally from what customers expect in term of features and performances requested of the SoC.

We’ll illustrate the major considerations designers will face when meeting application requirements with a 32bit microcontroller architecture design, and explain how to get maximum performance during software development by knowing the architecture and using common debugging techniques.

Ethernet Will Connect the Connected Vehicle

February 9, 2015  by  


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.

Considerations When Designing Board-level Functional Test Systems

February 6, 2015  by  


Automotive component suppliers are continually looking for ways to improve test efficiencies as they serve broader sets of customers and more complex application requirements. Some of the test methods used to ensure a quality product build post reflow include X-ray, In-circuit test, and Functional test. This article explores steps to configuring high-volume, high-mix functional test system standardizations along the production line, and how addressing interfacing from the measurement instrument all the way to the device under test I/O pin is a requirement to thoroughness of test and product quality.

The Top Technologies Enabling the Self-Driving Car

December 22, 2014  by  


Today’s advanced in-car technologies are ushering in the most dramatic evolutionary leap in automotive history since the Ford Motor Company was founded in 1903: Vehicles that operate without human intervention and a world where car crashes are history. While technology is being blamed for dangerous new driver distractions, it also promises to redefine the very meaning of highway safety. Technology never daydreams, never falls asleep, never reaches for hot coffee, and never tries to text on the freeway.

KEMET Offers Performance with Peace of Mind for Tantalum Capacitors

November 19, 2014  by  


For demanding applications such as automotive electronics, tantalum capacitors have been used for years because of their excellent stability at high temperature. The type typically specified for automotive use has a manganese dioxide (MnO2) cathode, which can withstand temperatures up to 200°C.

However, the manganese dioxide cathode devices have a disadvantage: their equivalent series resistance (ESR) isn’t as low as the polymer cathode types used in consumer electronics. Until recently, polymer cathode capacitors weren’t suitable for use at automotive temperatures and they also struggled to meet the humidity requirements for AEC-Q200.

By Paul Gray, CEO, Cohda Wireless

Cars are undoubtedly safer now than they ever have been, as evidenced by the steady decline of road fatalities. However, at the same time the number of injuries is actually increasing – passive safety technologies such as seat belts and airbags have simply made accidents more survivable. It is obvious that what is needed is ways of avoiding the accidents in the first place. Meanwhile traffic congestion, and its resulting environmental impact, continues to be a growing problem in cities around the globe. One simple technology has the potential to address all of these issues.
