Shelly Stalnaker Parasitic extraction is a pretty commonplace procedure these days in IC design. As geometries got smaller and more tightly packed, the resistance, capacitance and inductance of interconnects became significant enough to affect circuit performance. Accounting for these parasitic effects became a tapeout requirement, since they could cause signal noise and delays, as well as IR drop. EDA vendors stepped … Read More

John Day The past week or so has been relatively momentous for automotive Ethernet. – The OPEN Alliance (One-Pair EtherNet) Special Interest Group (SIG) announced the formation of several new technical committees, – the University of New Hampshire InterOperability Laboratory (UNH-IOL) announced expanded interoperability testing and support for 40 and 100 Gigabit Ethernet (40G/100G) including automotive … Read More

John McMillan PCB design engineers have had the front row seat to the evolution of touch screen technologies. In this HMI (human machine interface) driven world inwhich we now live, touch screens continue to replace buttons and keyboards in nearly every industry. Today’s “Generation Z”, carry around smartphones and have likely never had to press keys to make a call or to text a message. Many of … Read More

Colin Walls I am often asked where to get in-depth information about embedded software development. Commonly, the query comes from a student who thinks that it sounds like an interesting career option. Typically they ask how I got started, but, although I am willing to share my story, I am not at all sure that the details are still relevant – that was then, this is now. Maybe they are after advice on which … Read More

Motor Down

Posted by Mike Jensen

Mike Jensen In my last post I wrote about system reliability versus system robustness. I briefly explained my definition of the two, and suggested some design process shifts to help improve both. Sometimes the required process change is small; sometimes it is substantial, almost like an entire design paradigm shift. But the reward, whether measured in improved product reliability or robustness, is usually worth … Read More

John Day The more I learn about automotive electronics, the more excited I am about what’s coming in cars. I had the opportunity to see a bit of the future that’s available now when I tested the 2015 Subaru Outback, specifically, a 3.6R Limited with a 256-hp, 3.6 liter BOXER six-cylinder engine. The 2015 Outback is said to have a more “up-market” interior, presumably compared to last year’s model, with extensive … Read More

Vern Wnek As I sit here still recovering from the Thanksgiving feast of turkey and all of the trimmings, I am reminded that this is the time of year we give thanks and gifts to our friends and loved ones. Christmas is just around the corner, and the holiday season is in full swing. Speaking of giving thanks…I’d like to thank you for following along with me here on the blog! I also have an exciting announcement … Read More

Colin Walls I am continuing my catch-up process of cataloging embedded software articles that I have had published on This time they cover the influence of software on power management, using a memory management unit, all about the C/C++ keyword static and the basics of multicore … Device Power Consumption and the Choice of Operating System Device power issues are becoming increasingly important. … Read More

John McMillan Today, it’s hard to imagine a GPS that doesn’t list landmarks, street names, or even exit numbers. Every bit of visual information we can get from map symbols and text makes navigating easier and faster. The same is true for a PCB, yet we often overlook a great opportunity to provide a wealth of information about our PCB’s design on the silkscreen. The information we can, and should, supply on … Read More

ADEPT, the Advanced Diesel-Electric Powertrain project, is a 48V mild hybrid under development in the UK by technology companies including Ricardo, Ford, CPT, EALABC, Faurecia and the University of Nottingham. The vehicle was displayed at the 2nd International Conference on Advanced Automotive 48V Power Supply Systems. According to participants at the 2nd International Conference on Advanced Automotive

John Day IDTechEx Chairman Dr. Peter Harrop A new report from IDTechEx  predicts that over $125 billion will be spent on range extenders for electric vehicles by 2025. That’s for all kinds of electric vehicles. Pure electric vehicles – such as forklifts, golf carts, and mobility vehicles for the disabled – tend to be small and rarely need to travel long distances, but roughly half of the electric vehicle market … Read More

Robin Bornoff A lot of engineering involves the management of energies, converting them from one form to another, channeling off useful work to power our cars, planes, phones, lights etc. To date we haven’t come up with a system to channel all energy into a desired task. Even the most advanced power generation systems still end up heating water to steam to drive turbines, a cycle that is no more than about 38% efficient. … Read More

IoT revisited

Posted by Colin Walls

Colin Walls The Internet of Things [IoT] is a topic that appears in almost every news story or article in the world of embedded software right now. And it goes far beyond our immediate business – right across the electronics industry – as it is very much an encapsulation of hardware and software technologies. I wrote about IoT on this blog recently and someone suggested that I was rather dismissive … Read More

Rich Edelman SystemVerilog Testbench Debug – Are we having fun yet? Fun Debug should be fun. Watching waveforms march by, seeing ERRORS and WARNINGS pop out in a transcript file, tracing drivers back to their source, understanding race conditions between simulators and between source code changes – and my favorite – debugging random stability issues. Fun. Old School – logfiles and interactive Or at least it … Read More
