Colin Walls As I have done before, I am continuing to catalog a wide selection of my articles that have appeared at embedded.com. Another 4 today … Simulation – better than the real thing? With a complex embedded system, work needs to start on the software long before the hardware is available. Indeed, it may be necessary to commence work even before the hardware design is finalized. Software engineers need … Read More

Vern Wnek Recently at the IPC Council Meeting in Orange County, California, two of the top PCB design EDA vendors presented some of their current and upcoming technology for routing automation. The day was geared towards PCB designers and the methods they use for routing their designs. The day started off with the typical questions that we spoke of in my first blog in this series, The Myth of the Pretty Design, … Read More

Michael Ford While meeting with a customer recently, a PCB layout design engineer engaged in PCB routing using the very latest of Mentor’s Xpedition PCB routing software commented that he had never seen before how automated routing tools could create what he “saw” in his head. Perhaps this is a testament to how the Mentor PCB layout auto-router logic is getting to a level of cleverness approaching a human brain, … Read More

John Day At the Paris Motor Show recently Elektrobit (EB) and Nuance announced that they’ve integrated voice with natural language understanding (NLU) as part of the virtual cockpit in Audi’s TT Roadster. The virtual cockpit places infotainment as well as traditional dashboard information on a large screen directly in front of the driver. The point of integrating voice and NLU is to allow the driver to … Read More

Colin Walls I have been thinking about embedded operating systems and how a developer chooses from the options available. My thoughts partly come from the presentation that I made at the ARM conference in Munich last week. But I am also interested in ARM’s announcements in this area at ARM TechCon the week before. It seems to me that although it used to be very black and white, the rules are changing and … Read More

Chris Murray Hi I’m Chris and I’m a Fluid Systems Engineer.  I didn’t plan on becoming one on graduating from University and didn’t really know what one did but bluffed my way through an interview and got offered a job working for Flowmaster as a support engineer.  It can be difficult to explain to friends, family and customers exactly what I do and where a tool such as Flowmaster is used … Read More

Dennis Brophy DVCon India, held in September 2014 in Bangalore, built on the Indian SystemC User Group meeting events and added a Design & Verification track to its popular system-level design (ESL) track that has been popular for many years.  The main stage played host to the keynote presentations, opening ceremonies and best paper and poster awards. Several DVCon India keynote presentations, which I will go … Read More

John McMillan In today’s competitive marketplace companies cannot afford to have PCB production delayed because of slivers, unintended copper exposed by soldermask, testpoint-to-testpoint spacing, or other issues that should be identified and solved early in layout and long before manufacturing. Catching DFM issues at the design stage is critical because, at each successive step of the production process, the cost … Read More

Scott Salzwedel According to the FDA, the medical device you’re working on may no longer be fit to serve. What’s happening? Well, due to the critical nature of medical devices and the increasing role they serve in our lives today, government agencies are clamping down on the software running these devices. Unfortunately for you (and fortunately for the general public) enhanced government scrutiny and the need … Read More

Mike Jensen

If a system is reliable, is it also robust? And is the converse also true: does a robust system have to be reliable? The answers are no and yes. A reliable system performs its intended function when conditions are nominal. As long as design details and environmental conditions remain stable, you can count on a reliable system to do its job time after time. But what happens if these same design details

John Day Aftermarket in-dash infotainment system supplier Pioneer Electronics is moving rather aggressively to meet consumer demands for infotainment and smartphone connectivity. After all, it costs far less to upgrade a car’s in-dash system than it does to buy a new vehicle. Last summer Pioneer launched an iPhone app called AppRadioLIVE to work with the company’s AppRadio in-dash receivers. It’s intended to … Read More

A Day at the Zoo

Posted by Nazita Saye

Nazita Saye Computational Fluid Dynamics (CFD) is pretty serious business. Every day it’s used in a wide range of industries around the world to optimize products for some very practical purposes. Cars? Check! Planes? Check. Medical devices, consumer electronics and power generation? Check, check and check.  But sometimes you come across things that make you giggle. And since it’s a grey and gloomy day in … Read More

Colin Walls Hot on the heals of ARM TechCon in California last week, I am off to another ARM-centric event on Thursday this week: the ARM Developers Conference in Munich, Germany. This timing was no coincidence. It was originally scheduled for early summer, but it was moved to take advantage of ARM’s announcements at TechCon. I will be making a presentation titled “OS Selection for ARM-based Systems”. … Read More

Leg Hair? What a Drag

Posted by Robin Bornoff

Robin Bornoff “How thick is a leg hair” is not a question I thought I’d be posing when I woke up today. Reading this article about the effect of leg hair on the overall drag of a performance cyclist prompted me to investigate the physics behind this observation. For the sake of expediency I steered clear of a full body MAMIL simulation, focussing instead on just a small patch of a particularly hairy … Read More
