Silence Is Golden
By Ann Mutschler - 01 Dec, 2010 - Comments: 0

As the industry continues to march along building devices with ever-increasing battery life, it is necessary to migrate to the latest and greatest process nodes, which as we all know are smaller and use lower voltages. However, any noise in the system—whether it was there before or you start to use something like USB 3.0 or SATA or something else—is actually going to increase the number of ... » read more

Getting Some Respect
By Atrenta - 18 Nov, 2010 - Comments: 0

He’s a comic legend. The master of the one-liner. I had the good fortune of being in a comedy club in New York City one evening a long time ago when Rodney stopped by to try out a new comedy routine. He simply walked in and took the microphone for 45 minutes. Apparently, he did those impromptu appearances a lot “back in the day”. One of Rodney’s most famous one-liners is “I don't get ... » read more

Power To Fly
By Barry Pangrle - 04 Nov, 2010 - Comments: 0

By Barry Pangrle As technologies mature, they often follow similar profiles. Back on Oct. 14th I heard Lesley Curwen of the BBC interviewing Charles Champion, executive vice president of engineering at Airbus. Champion said that over the last 40 years the airline industry has reduced emissions and fuel burn by 70%. He pointed out that the industry initially focused on speed and the tendency no... » read more

Making Power Delivery Networks Better
By Ann Mutschler - 04 Nov, 2010 - Comments: 0

Careful design of power delivery networks can make the difference in whether a chip manages power effectively or fails completely. This impact of cost and other factors in the design process has not gone unnoticed. Aveek Sarkar, vice president of customer support and product engineering at Apache Design Solutions, pointed to the iPhone as an example, where 50% or more of the bill of material... » read more

Should EDA Remain Coin-Operated?
By Atrenta - 21 Oct, 2010 - Comments: 0

The EDA business model has seen a lot of discussion. Perpetual, time-based, pay as you go, EDA cards, etc., etc. The implications of the chosen business model can have dramatic effects on the overall health of the company involved. Changing the business model can cause mighty companies to topple and weak companies to seem strong (at least for a while). Current trends, such as cloud computing, p... » read more

The Good Kind Of Bias
By Barry Pangrle - 07 Oct, 2010 - Comments: 1

By Barry Pangrle Back gating, body bias, substrate bias, and back bias all refer to a technique for dynamically adjusting the threshold voltage of a CMOS transistor. CMOS transistors are often thought of as three-terminal devices with terminals for the source, gate and drain. It’s quite common, though, to have a fourth terminal available connected to the substrate (or body). Most engineer... » read more

Power Intent Files Drive Low Power Adoption
By Luke Lang - 07 Oct, 2010 - Comments: 0

By Luke Lang “The adoption of EDA tools is actually a very slow process.” This quote by Wally Rhines of Mentor Graphics was highlighted in a red box in the June 2010 issue of EDA Tech Forum. I don’t think most of us would argue with that statement. But there are certainly exceptions to that rule, and low-power design with a power-intent file is one such exception. The concept of a pow... » read more

The Value Of Adaptive Body Biasing
By Bhanu Kapoor - 07 Oct, 2010 - Comments: 0

By Bhanu Kapoor Although the use of power gating techniques is essential to manage standby leakage power, it brings in a host of new design and verification issues. This list of new design and verification issues includes putting together a power switch network, incorporating appropriate isolation and retention, addressing x-propagation, dealing with current spikes, and ensuring retention work... » read more

Connecting IP Blocks
By Ann Mutschler - 07 Oct, 2010 - Comments: 0

Is there a standard way to hook up specifically low-power IP blocks today? For all intents and purposes, no. Before even talking about IP interoperability in terms of power, Philippe Magarshack, general manager of central CAD and design solutions at STMicroelectronics asserted those IPs must be hooked up correctly functionally and in a productive and safe way. He said ST is forging ahead ... » read more

Why The Early Edition Was Late
By Atrenta - 23 Sep, 2010 - Comments: 0

By Mike Gianfagna I was a little late with the Early Edition this month. This is kind of embarrassing given the name. Anyone in EDA sales will understand why. It’s the end of the quarter, about a week to go. I’ve been really, really busy. Many EDA companies will book more than 50% of the quarter’s business in the next week. The bean counters have a name for this phenomenon: the ho... » read more
