Making DFM Work Better
By Ann Mutschler - 17 Dec, 2009 - Comments: 0

By Ann Steffora Mutschler At 65nm, design for manufacturing optimization and analysis has mostly been an afterthought. At 40nm and beyond, DFM has been pushed well up into the design phase. There are good reasons for this shift. What emerged at the 65nm node were signoff tools that understand manufacturing used in semiconductor design, said Manoj Chako, a product director for digital si... » read more

The Ins And Outs Of Power Conversion
By Ed Sperling - 10 Dec, 2009 - Comments: 0

By Cheryl Ajluni Power conversion is a general term that refers to a system or device producing an output that is different than its input. It can assume many forms—everything from an inverter to an isolated power supply, uninterruptable power supply (UPS), or AC/DC converter. Power conversion, like low-power design, is fairly commonplace these days. Nevertheless, recent advances in digital ... » read more

Reducing Power In Plasma Display Panels
By Various Writers - 10 Dec, 2009 - Comments: 0

By the EEFocus staff In early 2009 there was a lot of coverage in the media at home and abroad about plasma display panel (PDP) TV sets being banned in the EU. Paul Gray, Director of European TV Research, denied the claim but did mention that they were planning to set minimum energy efficiency standards for flat-panel TVs and set maximum energy consumption limits according to screen sizes. He ... » read more

Greener Data Centers
By Ed Sperling - 10 Dec, 2009 - Comments: 0

By Ed Sperling For decades the race inside the data center was all about performance. If you upgraded from an IBM Series/370 mainframe to a Series/380 your applications ran faster. And if you upgraded your PC server from a Pentium II to a Pentium 4 you got significantly better performance. The race now is to reduce the number of servers altogether, to lower the cooling costs per server ra... » read more

Differentiating Embedded Processors
By Ed Sperling - 10 Dec, 2009 - Comments: 0

By Ann Steffora Mutschler The embedded processor world addresses a vast range of applications – from the datacenter to the biomedical device – all of which have critical power needs that vary with the use. Power concerns continue to dominate the embedded system whether it is avoid a noisy fan in a TV set-top box, allow video on a mobile phone or minimize pricey cooling costs in the datac... » read more

Experts At The Table: Rising Complexity Meets Verification
By Ed Sperling - 04 Dec, 2009 - Comments: 0

Low-Power Engineering sat down to discuss rising complexity and its effects on verification with Barry Pangrle, solutions architect for low power design and verification at Mentor Graphics; Tom Borgstrom, director of solutions marketing at Synopsys; Lauro Rizzatti, vice president of worldwide marketing at EVE, and Prakash Narain, president and CEO Real Intent. What follows are excerpts of that ... » read more

With ESL, You Are Your Ecosystem
By Ed Sperling - 01 Dec, 2009 - Comments: 0

Where are the weak links in the ESL ecosystem?   That question isn’t idle speculation. With complexity in many SoC designs reaching well beyond the level of human comprehension—even beyond the capabilities of the most brilliant engineers or architects—chip developers on all levels need to know what can go wrong from both a technology and a business standpoint.   No company can dev... » read more

More Choices But Less Design Freedom
By Ed Sperling - 19 Nov, 2009 - Comments: 0

By Ed Sperling “What if” is an indelible part of the lexicon of every SoC architect and design engineer from the front end of the design flow all the way to manufacturing, but while the terminology will persist for years to come the answers and the value of those answers are starting to change. Complexity, cost and the need for better integration have simultaneously increased the numb... » read more

Methodology Shifts Ahead
By Pallab Chatterjee - 19 Nov, 2009 - Comments: 0

By Pallab Chatterjee The high cost of SoC development at advanced process nodes is forcing a significant shift in many of the methodologies used in design. Hierarchical design methods are giving way to IP integration and hierarchical analysis at the architectural and functional design levels. Previously, large blocks were implemented at the top level of the chip and the analysis was pushe... » read more

Return Of The Femtocell
By Cheryl Ajluni - 19 Nov, 2009 - Comments: 0

By Cheryl Ajluni Nothing has been left unscathed in the current global economic downturn, and that includes femtocell deployments. It was just last year that femtocells were being proclaimed a 2009 “killer app,” along with LTE and WiMAX. But what was once viewed as the next great thing has instead faced a tough road with more than a few large-scale deployments by major mobile operators be... » read more
