Matthew Ballance Between 2006 and 2014, the average number of IPs integrated into an advanced SoC increased from about 30 to over 120. In the same period, the average number of embedded processors found in an advanced SoC increased from one to as many as 20. However, increased design size is only one dimension of the growing verification complexity challenge. Beyond this growing-functionality phenomenon are new layers … Read More

Hitting 100 ohms, the right way

Posted by Patrick Carrier

Patrick Carrier When designing the trace configuration for your differential pairs, you are typically targeting 100 ohms differential.  That means each trace would be a 50-ohm trace, if there were no coupling between the traces.  But, you usually want some decent coupling between the traces, so a good single-ended impedance target for each trace is between 60 and 75 ohms.  That means that the differential pairs will … Read More

Tom Fitzpatrick When I was at DAC this year, I had a few folks come up to me at our Verification Academy booth and suggest that I do a “Recipe of the Month” webinar on UVM sequences. They’d seen plenty of information on sequence mechanics and generating stimulus with sequences, but these users were particularly interested in Slave sequences, which aren’t necessarily very intuitive. Of course, … Read More

Colin Walls The Fall is a big time for conferences and this week will see me clocking up some more air miles as I visit two events in Europe. The first conference is in Stockholm, Sweden – Embedded Conference Scandinavia [ECS]. I attended this lively event last year and on several previous occasions. This year, I have two presentations, both on Tuesday: At 10:00: Self-testing in Embedded Systems At 14:00: … Read More

Danit Atar PCB design is a complicated task, partially because each design task has an effect on the outcome of the rest of the design stages. Get your ducks in a row ! Of course, you need to design your schematic, make sure you have no signal- and power-integrity issues, place your components, route your board, make sure your design can be manufactured, and so forth. But how much more complicated is it when … Read More

When Reliability Goes Up in Flames

Posted by Shelly Stalnaker

Shelly Stalnaker I recently returned from my first-ever trip to Japan. While I was enthralled by its beauty and history, entertained by both traditional and avant-garde theatre, and enticed by new food opportunities, it was five minutes of television that caught my attention one day. Although I didn’t understand a word of the report, the problem was obvious—all over the region, vending machines were spontaneously … Read More

J VanDomelen NASA has increased its reliance on private, commercial space companies following the retirement of the U.S. Space Shuttle program in 2011. Among NASA’s growing list of commercial partners is Orbital Sciences Corp. in Dulles, Virginia. The Antares launch vehicle, from Orbital Sciences Corp., is the largest rocket produced by the company and the largest to be launched from the Mid-Atlantic Regional Spaceport … Read More

John Day Bosch noted this week with some justifiable pride that the electronic stability program (ESP) it pioneered becomes a standard in the European Union as of November 1. From there on in the EU, all newly registered passenger cars and light commercial vehicles with a gross vehicle weight of up to 3.5 metric tons must be equipped with the anti-skid system. The regulation will take effect for all other vehicles … Read More

J VanDomelen NASA personnel have gotten really good at social media. In fact, NASA engineers, scientists, and officials have been taking to various social media and news outlets, generating a great deal of excitement over a night launch on the East Coast of the United States. Military and aerospace (mil/aero) enthusiasts everywhere – this mil/aero geek included – watched with bated breath for what was to be an historic … Read More

J VanDomelen India solidified its place in the history books when late last month (September 2014) the Mars Orbiter Mission (MOM) and technology demonstrator successfully entered into orbit around the Red Planet. The MOM achievement launched India into aerospace history as the first nation in Asia to reach Mars—joining the ranks with the European Space Agency (ESA), U.S. National Aeronautical Space Administration … Read More

Nazita Saye My appreciation of gadgets isn’t anything that should surprise you. I’ve already talked about a few and some have proven more useful than others. For example, my Fitbit One accompanies me on every hike so I can track and then bore my friends with all kinds of useless information while some gadgets such as my waffle iron were bought rather impetuously and get dusted once every blue moon … … Read More

Colin Walls When I made the very first posting  to this blog, more than five years ago, I made the observation that the world of embedded software is very fashion conscious. I certainly do not mean that embedded software developers are renowned for their dress sense! I am talking about the way that a particular technology is really “hot” at any one time … Every few years, a product or technology … Read More

J VanDomelen The global aerospace community is buzzing with news of emerging markets making technological advances and historical achievements. Among the nations making headlines is India. Indian Space Research Organization (ISRO) officials in Bangalore are racking up aerospace wins, which resulted in India being recognized as the first Asian nation to successfully send a satellite into orbit around Mars. India’s … Read More

J VanDomelen When you think of aerospace innovation, what nations come to mind? The United States, Canada, Russia, and the European Union have all logged significant, if not historical, aerospace achievements. At the same time, military and aerospace (mil/aero) industry pundits recognized Brazil, China, India, Mexico, and South Africa as the emerging aerospace markets to watch. Watch we have, and aerospace geeks … Read More

Robin Bornoff There are 475,000 Google search hits for ‘thermal bottleneck’. It’s a well recognised phrase playing on a very obvious analogy. Despite this there were few attempts to quantify such a parameter. Spurred on by its relevance in electronic thermal design, we did just that, put hard numbers to the concept. FloTHERM now has the ability to plot distributions of  thermal bottleneck, enabling … Read More
