7/29/2004 - Sequence Design is leading the charge along with Artisan Components, Inc., (Nasdaq:ARTI) and Sun Microsystems, Inc. (Nasdaq:SUNW) in sponsoring NanoCool(TM) seminars that will explore logical and physical low-power design methodologies. Novas Software, Inc., Golden Gate Technology Inc. and Tensilica, Inc. will also present at the seminar.
RTL power estimation, power debug, voltage-drop analysis, power modeling, power grid design and leakage reduction will all be explored during the seminar. Dennis Sylvester, professor at the University of Michigan, will be the keynote speaker at the San Jose seminar. The topic of his keynote will be "New Approaches to Total Power Reduction Including Runtime Leakage."
"Today, effective power management is the key to nanometer SoC design success," said Vic Kulkarni, Sequence president and CEO. "Sequence along with its partners is leading the new era of 'power-aware' design."
According to Neal Carney, Artisan's vice president of marketing, "To overcome the complex nanometer design challenges and gain greater confidence in meeting power and performance budgets, it's important to provide IP that supports various power reduction solutions that include accurate power and signal integrity modeling."
"The power problem is the No. 1 issue in the long-term for computing. It's time for us to stop making 6-mile-per-gallon gas guzzlers," said Greg Papadopoulos, chief technology officer with Sun Microsystems (San Jose Mercury News, 7/2/04).
The Challenges to Power Management
The earliest forms of low power design involved the basic practice of reducing the power supply voltage, either in the entire design or in certain parts. The attractiveness of this approach was, and still is, the quadratic relationship between the supply voltage and the resulting power consumption. An additional method involves the use of more advanced semiconductor processes with narrower transistors and shorter wires -- all else being equal, the reduction in parasitic capacitances due to the smaller geometries results in less dynamic power.
Today, these approaches are no longer enough and in some cases -- such as sub-threshold leakage -- counter productive. "10X reductions in leakage can be achieved through the use of smart power gating techniques," said Jerry Frenkil, vice president of advanced development with Sequence.
The time for a comprehensive RTL to sign-off power integrity solution is now. "Being able to run power analysis at RTL is very important because it allows us to get a handle on power consumption very early in the design process, and then make appropriate changes to reduce power," said Himanshu Sanghavi, hardware engineering manager, Tensilica. "By getting these insights at RTL, we can meet our power goal more efficiently."
"Debugging power-related issues is critical when dealing with large complex designs with low power restrictions," said Dave Kelf, vice president of marketing at Novas. "Being able to analyze localized power problems accelerates silicon closure while enabling higher degrees of design performance optimization."
"Power reduction at the RTL and device level no longer needs to be given back with physical synthesis," said Tom Minot, vice president of marketing and sales, Golden Gate Technology. "At the physical level, effective power grid design must account for power consumption at RTL. An under-designed grid can lead to significant voltage drop and design closure challenges."
The NanoCool seminar series will kick off with the first seminar at Capital Club Athletics in downtown San Jose on Wednesday, August 04, 2004.
