A Smart System Technology Renaissance


By Margaret Schmitt Leonardo da Vinci invented fantastic machines to revolutionize how man would live, work, wage war, and travel. Describing how he conceived these designs he said, “A painter should begin every canvas with a wash of black, because all things in nature are dark except where exposed by the light.” We currently are experiencing a renaissance of our own, with the rise of s... » read more

Electronic Power And Thermal Management


Highly complex systems require integrating a large number of electrical components within a very limited space. This creates challenges for power and thermal management not seen in previous generations of electronic systems. To be successful, plans must incorporate advanced power and thermal management strategies from the earliest stages of the design process and assess power and thermal issues... » read more

Low-Power Verification


Low-Power Engineering talks about how to verify the power portion of semiconductor designs with Krishna Balachandran of Synopsys; Barry Pangrle of Mentor Graphics; Kalar Rajendiran of eSilicon; Will Ruby of Apache Design, and Lauro Rizzatti of Eve-USA. [youtube vid=covy6ku6RgA] » read more

Status Report: Power-Aware Design Flow


By Ann Steffora Mutschler While the term “design flow” can be a moving target, there are some specific requirements for a low-power/power-aware tool flow. Looking at this from a high level, where is the industry today, and where is it headed? There are really two sides to power, which are almost like two sides of the same coin: power consumption and power integrity. And both of those ar... » read more

Rethinking Good Enough


By Ed Sperling Power has been elevated from an afterthought to one of the top considerations and tradeoffs in SoC design, edging out performance and area in many cases and in some cases even cost and features. Tradeoffs in design always change, depending upon what the most pressing concern is among consumers at any time. For decades, performance was always the top of anyone’s list, follow... » read more

Thinking Differently About Power


By Ed Sperling Battery life and lower electricity bills are now marketing tools for makers of SoCs, the mobile devices they go into, and servers that power data centers. A smart phone battery that lasts through the day without a charge, even when the user is playing high-action games, is a lot more attractive than one lasting only a few hours. And a data center electricity bill that shows a sh... » read more

Better Power Planning


By Preeti Gupta Making the right architectural decisions for controlling power consumption and ensuring power integrity requires early identification and quantification of varying current demands in a semiconductor design. Furthermore, low-power designs pose complexities for power verification, such as significant current surges caused by clock gating or power gating transitions. In last mo... » read more
