J VanDomelen 2014 has been an outstanding year for aerospace, and particularly the commercial space and commercial aviation market segments. In fact, the military portion of the military and aerospace (mil/aero) industry has been in the doldrums of late, especially in the United States and European Union, in the age of tightening defense budgets. Commercial aviation and commercial space took their knocks this year, … Read More

J VanDomelen Transportation is a hotbed of activity, and an industry vertical that is garnering as much attention as it is investment. By drilling down into different market segments, we see positive numbers and continued innovation. The automotive sector continues its strong progression, with global automotive sales reaching a record high in 2013, with more than 82 million sold and a growth rate of more than seven … Read More

John Day This isn’t quite ready yet but it should be quite something to see when it is. Jaguar Land Rover is conducting research the goal of which is (1) to make a car’s A, B and C pillars transparent to improve visibility and (2) to project an image of a vehicle in front of the driver’s car – a ghost car, as it were – for the driver to follow, turn-by-turn, until the desired destination is reached. Pillar-wise, … Read More

Colin Walls As embedded systems become even more ubiquitous and complex, there is an increasing concern about security. The term means different things to different people, but I am thinking of the requirement for systems to be less vulnerable to tampering. Security measures are aimed at preventing, deterring or delaying the work of a hacker, who is trying to change the functionality of the device in some way. … Read More

Vern Wnek Typically my blogs speak of PCB layout technology and the company I work for, but this one is a bit different. During this season of reflection and celebration, I’d like to take some time to honor the special friends that have passed during the year. We place these friends and our fondest thoughts “into memory,” in hopes to keep their legacies alive. I’d also like to recognize another great PCB … Read More

Shelly Stalnaker A few weeks ago, I introduced you to the start of a DFT Bootcamp series for those of us who wouldn’t know a DUT if we ran into one. Maybe you design ICs, but someone else adds the test circuitry to your layouts. All you know (grumble, grumble) is that those additions can change your design’s performance, increase the die size, and require additional verification. But even if you’re … Read More

Robin Bornoff Human technical prowess relies heavily on the conversion of energy from one form to another, to meet our needs. Physiological needs underpin  Maslow’s pyramid of all our other ones. The availability of hot water is in turn important for that. Likely we’ve been heating water since the early Neolithic, converting chemical energy stored in wood to heat (radiative and convective) which in turn … Read More

Tom Fitzpatrick Just in time for Christmas and other year-end holidays, I am pleased to announce that the latest issue of Verification Horizons is now available on-line. As usual, we have a great lineup of articles that I’m sure you’ll find informative: Integrate Ethernet QVIP in a Few Hours: an A-to-Z Guide - Shows how to instantiate a Questa VIP (QVIP) component quickly and easily into your UVM environment, … Read More

Paul Johnston Enterprise class software used by electrical engineers – Mechanical 3D CAD, Product Lifecycle Management and Engineering Requirement Tracking Systems, Enterprise Resource Planning, is subject to scrutiny from users who find opportunity for improvement. I have yet to work with a perfect piece of software. I’m going to share with you in the next few posts how you as a customer can contribute make Capital … Read More

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

System Modeling

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
