Patrick Carrier There are a lot of reasons to mix SI and PI analysis – trying to figure out a worst-case stimuli to determine PDN performance, trying to see the effect of a poor PDN on signals due to SSN issues, or just being able to properly analyze a single-ended via.  In fact, to get an accurate model of a single-ended via, you have to mix SI and PI.  The reason is that the power distribution network, or PDN … Read More

Colin Walls In a recent post I mentioned that I have written a lot of articles over the years. I sometimes wonder how many, but it is certainly in the hundreds. Although historically they were in print, nowadays, most of my work appears online. A particular favorite outlet is a popular venue for embedded developers: embedded.com I have cataloged and highlighted some more of my work … In due course, I will … Read More

Robin Bornoff Develop 3D is a UK based Magazine and Website focussing on the technologies involved in product design. The latest copy had a fascinating article on Dell’s Precision Workstation labs. This blog is being written on a Precision M4500 which I’ve lugged around countless airports and dumped, wearily, on numerous hotel beds. The fact that it works as well now as when I first got it a few years ago is … Read More

Shelly Stalnaker The 9th annual International Electrostatic Discharge Workshop (IEW) is being held May 4-7, 2015, at the Granlibakken Resort in Lake Tahoe, CA. The Call for Papers promises glimpses of “friendly but shy” bears and other wildlife at the conference site, located at 6,350 feet up in a mountain valley. Frankly, I prefer my bears to be decidedly shy, if that means they’ll be close enough … Read More

John Day When Agero, best known for its roadside assistance services, introduced a smartphone-based telematics system for usage based insurance (UBI), I wondered about the benefit(s). Agero said its system offered advantages over OBDII hardware solutions for assessing behind-the-wheel behavior, but those advantages weren’t immediately obvious, so I asked Jeff Blecher, Agero’s senior VP of strategy, about them. He … Read More

Doug Kolak Do you have an upcoming project and don’t have a tool that can handle system level thermo-fluid analysis? Are you evaluating your current simulation options to make sure they meet the needs of your business for years to come? Are you curious about new ways of solving problems of the world today in particular with the use of CFD? If you are like most engineers I speak with, the process for getting access … Read More

Hello World

Posted by Don Miller

Don Miller My blog series will cover the historical context which lead to the creation of Internal Flow Systems. Encompassing both the motives and the methods behind the book, the series will inevitably raise questions about the reliability of many of the other available sources of available data. I also hope to make clear this isn’t a subject of academic interest alone; the subject of loss coefficients … Read More

Robin Bornoff A release so good it has 11 best top 10 features, very Spinal Tap. I thought I’d wrap up this series with a list of more minor, but imo, very useful features and finish off with some words on cultural idioms. FloTHERM V10.0 and V10.1 together satisfy about 60 software enhancement requests as voted for on the Mentor IDEAS site for Mechanical Analysis Products, a strategy we’ve been committing … Read More

Robin Bornoff Arguably the most important (and often least well characterised) parameter controlling the temperature of electronic products is their power dissipation. Usually dissipated on the active layer of a die, this heat power seeps through the die, package, PCB, air, chassis all the way to the ambient in which the product sits. The less heat power the better, the lower the temperature rises that occur. The … Read More

Robin Bornoff FloVENT, FloTHERM’s sister product aimed at 3D CFD simulation of the built environment, has for many years been able to simulate the thermal behaviour of a data center. After all a data center is a built environment, albeit more for servers and the like than humans. We’ve not changed this capability of FloVENT but we have copied the relevant data centric features over to FloTHERM, extending … Read More

Patrick Carrier Power integrity (PI) is an analysis discipline that has been around for years.  Signal integrity (SI) has been around for a few more years.  Basically, they both deal with the proper analog operation of digital circuits.  So why these specific realms of analysis?  The main issue is that there is no such thing as “digital” – what we call “digital” data transmission is really … Read More

John McMillan You sent in the questions – Now lets get the answers ! Join me September 9, 2014 for our first Video Roundtable Q&A Event. I’ll be asking  the PADS Product Marketing Manager Jim Martens and Product Line Director Mike Griesbach the PADS VX questions YOU have submitted. Perhaps you’re already started using VX. Perhaps you’ve downloaded VX but have not started a new project … Read More

John Parry Come and join us for THERMINIC 2014 in (hopefully) sunny London! The 20th IEEE Workshop on THERMAL INVESTIGATIONS OF IC’s AND SYSTEMS (THERMINIC 2014) to be held at the magnificent World Heritage Site in Greenwich, London, is on 24-26 September. This year, as part of the 20th Anniversary celebrations, there will be a boat trip up the river Thames, followed by a trip around the London Eye! It’s a great … Read More

Michael Ford As humans, it is said that we consume between 2,000 and 2,500 calories per day of energy, 1,300 of which are used just to keep the body alive, including about 300 calories for the brain. The numbers vary from difference sources and of course are averages. Calorie consumption for the brain is said to range from 0.1 of a calorie per minute, up to around 1.5, probably the difference between watching the … Read More

Colin Walls As I mentioned on a previous occasion, I always welcome questions whenever I make a presentation, do a web seminar, write an article or blog post or whatever. Even very simple queries give me ideas for topics to discuss. I always take the view that, if one engineer poses a question, there are probably a bunch of guys who would also like the answer. Once again, I am turning my attention to C++ … What … Read More
