In my previous blog I made the point that the increasing focus on energy efficiency means that the subject of loss coefficients remains an extremely relevant one.  If the topic were owned or regulated then these blogs would be unnecessary.  However, the fact is that non-replicable results proliferate in the literature, making it difficult for he concerned engineer to exercise ‘due diligence’ in designing

Michael Ford It is a human trait that it seems we all possess. We think that to be a part of a group makes us stronger. There is however more to it than that. There are many types and indeed tiers of grouping, which start to affect us as soon as we’re born. Am I male or female? The family group to which I belong. The family house, a part of a local community, a village, a town, a region and a country, an ethnic … Read More

John Day Electrical Systems (ES) engineers at the Toyota Technical Center in Saline, Michigan, spent months engaged in customer research in the course of designing the 2015 Toyota Avalon premium midsize sedan that launched this week. The research included clinics, focus groups, surveys, and visits to dealers. “A tremendous effort goes into designing a car that meets design goals,” says Avalon chief engineer … Read More

Robin Bornoff Lighting accounts for ~20% of the world’s total energy consumption. This is a staggering statistic. Why so much? Historically a lot of energy had to be consumed to produce the required amount of visible light. Incandescent bulbs, where electric current is used to heat a metal filament, resulted in most of the energy being dissipated as heat. More a hot bulb than a light bulb. Even worse for a … Read More

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

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
