Mention of EMI/EMC-induced automotive system failure in the press last week coincided with one of the bigger technical conferences held annually in Silicon Valley – DesignCon. It was in this conference two years ago that we organized a workshop on chip–package–system simulation methodologies specifically as they pertain to EMI/EMC analysis.
Electromagnetic interference, coupling and susceptibility are complex topics. To predict such an event or occurrence requires design teams separated by organizational boundaries to collaborate effectively “outside” the silos they reside in. An automotive system design company working on the next-generation air-bag control system will be responsible for designing the printed circuit board (PCB) to meet stringent performance, reliability and cost metrics. Its teams typically perform numerous simulations to ensure that the board, by itself, meets the requirements outlined for the team. However, PCBs are passive electrically. They (along with the cables) radiate only when the integrated circuit (IC) that is present on these PCBs performs the necessary operations and generates current flow through the various traces.

Happy Friday, folks! This week’s roundup of interesting engineering technology news articles includes a look at how one engineering family celebrates the holiday season, more cool technology for your car and a high-level look at optimization with simulation.
It was a short work week for us here in the U.S — Thanksgiving! The United States is a bit preoccupied with overindulging in Thanksgiving dinner, football watching, and shopping for the latest consumer gadgets on Black Friday, but we were able to find a few other important stories happening in the area of engineering technology. Enjoy!
Happy Friday, folks! For this week’s roundup of interesting engineering technology news articles, be sure to check out Disney’s video showing how their engineers celebrate Halloween and learn how one British company is changing the world of energy as we know it. Oh, and turns out Cinderella’s glass slipper could indeed support her weight as she dances the night away with her prince charming!
On October 30 – 31, ANSYS will be hosting the Automotive Simulation World Congress (ASWC) in Detroit, Michigan. This international event is being held at the Detroit Marriott at the Renaissance Center and is solely focused on the automotive industry, including vehicles for road, rail, racetrack and off-highway and provides a forum for sharing and debating new practices, issues and industry trends. You’ll learning about the latest developments in engineering simulation applicable to the automotive industry, and networking with peers. Continue reading →
The Formula 1 engineer is the royal class of automotive engineering. Even the smallest improvements in aerodynamics, engine performance, traction or durability can influence a team’s success or failure. Each of the F1 teams have a large number of highly qualified engineers working on each part of the car to improve its overall performance. Where do these engineers come from? Is there a given educational path a person should follow to get a chance to work for an F1 team? Next to a sound engineering education and the right motivation and will, probably not. But there are some initiatives that are helpful on the way to the automotive engineering summit. One of them is Formula SAE/Formula Student. Continue reading →
The Obama administration recently mandated an ambitiously high Corporate Average Fuel Economy (CAFE) standard – 54.5 miles per gallon by 2025. In other words, every car maker will have to ensure that the average fuel consumption of all the cars it sells in the United States in 2025 should be 54.5 mpg or more. CAFE standards have been mandated by the government for the past few decades, but a quick look at past standards provides a perspective of the steepness of the current hike. In 2009, the government set CAFE standard at 35.5 mpg for model years of 2017 and beyond. This was a 30 percent increased compared to the CAFE standard for the 2010 model year. In comparison, the CAFE standard set for 2025 represents a 54 percent hike above the 2017 standard. How will the car-makers achieve such a significant jump?
