Too Many Standards, But Still Not Enough
By Ed Sperling - 15 Dec, 2011 - Comments: 0

By Ed Sperling The semiconductor industry has been one of the most prolific sectors in history when it comes to generating standards. Talk to any design engineer facing time-to-market pressures, new packaging approaches, and a mindboggling number of merchant IP, subsystems and interface requirements, and you’ll hear a compelling pitch for new standards. Talk to his or her boss and you’ll p... » read more

Model-Driven Design: Making Progress
By Ed Sperling - 15 Dec, 2011 - Comments: 0

By Ann Steffora Mutschler Model-driven design is coming into its own, in part because the old way of using models at advanced nodes doesn’t always produce usable chips and in part because of the need for making tradeoffs at the earliest stages of the design process. The concept of developing models for IC design is hardly a new one, and it is being done today on a number of levels rangin... » read more

Tech Talk: Comparing Smart Phones

What makes one smart phone last longer on a charge than another? The answer may surprise you. Low-Power Engineering talks with Cary Chin, director of technical marketing for low-power solutions at Synopsys, about what his months of research have shown. [youtube vid=BUefmd_oFp8] » read more

After The Ball Drops
By Atrenta - 14 Dec, 2011 - Comments: 0

Growing up in New York City leaves lasting memories. The coming holiday season evokes some strong ones. The Christmas tree in Rockefeller Center is an example. Christmas always seemed to radiate in all directions from that huge tree perched above the ice skating rink behind Radio City Music Hall. And then there was the ball dropping on New Year’s Eve in Times Square. For the most part, New Yo... » read more

The Power Of Analog
By Ed Sperling - 01 Dec, 2011 - Comments: 0

The shift into stacked die, expected to begin late next year with a big ramp in 2013, will shine a spotlight on analog design and its effect on power. For years, analog engineers have bragged about just how efficient their portion of a chip was versus digital. We’re about to find out if they’re right. Stacking die will, to a much greater extent, decouple analog from digital and leave it ... » read more

Playing The Voltage Game
By Ed Sperling - 01 Dec, 2011 - Comments: 0

y Ed Sperling Scaling down the voltage to boost battery life and cut energy costs has always been considered the best option, but it’s getting more difficult at advanced nodes and in stacked die packages. The key problems are noise and leakage. Lowering the voltage exacerbates both of them, forcing a rethinking of the whole design process starting at the architectural level and continuing... » read more

Bridging The Gap
By Ann Mutschler - 01 Dec, 2011 - Comments: 0

We talk all the time about hardware/software co-design, co-verification, etc., but what is really interesting now is how vital the connection is between power awareness and system-level design. Yes, it sounds obvious, but so far this is an untapped market with ideas still being batted around. As discussed in Parts 1, 2 and 3 of my article series on energy and power, to achieve the best power... » read more

Pest Control
By Achim Nohl - 17 Nov, 2011 - Comments: 0

By Achim Nohl Identifying and describing power issues is tough, let alone trying to solve them. “Power” issues can be very diverse. It’s even more difficult to explain how virtual prototypes can help to analyze “power” consumption. We often approach it by introducing how power information can be reflected in virtual prototype models, but there are many different goals and conflicting... » read more

Make Vs. Buy
By Ed Sperling - 17 Nov, 2011 - Comments: 0

By Ann Steffora Mutschler The confounding ‘make versus buy’ decision is understandably muddled by design complexity. Millions of gates, thousands of blocks, dozens of cores, plus software, packaging, and worries about physical effects don’t make this decision any easier. In some cases the process can be simplified by mandating that anything that doesn’t add differentiation really is... » read more

Build It Faster
By Ed Sperling - 17 Nov, 2011 - Comments: 0

By Ed Sperling Hitting market windows with IC designs has always been a struggle, but the race to the finish line is becoming more critical—and much more difficult. The reason: Market windows themselves are shrinking. Products that used to stick around for years may now only last for months, replaced by newer versions that offer either better performance or lower power. In many cases, par... » read more
