Power Reduction In A Constrained World

Back when 40-28nm were new, leakage power for wireless designs dominated the optimization technology focus. This led to multiple VT optimization and power intent management for digital designs to minimize or shut off leakage. As wireless devices moved to FinFET nodes, dynamic power became dominant. As a result, optimization technology focus shifted to build up dynamic techniques to complement y... » read more

One PHY Does Not Fit All

Consumers expect their battery-operated mobile devices to be faster, smaller and more reliable while providing greater functionality at a reduced cost. Most of all, consumers demand longer battery life and 24/7 access to data. To meet these demands, consumer system-on-a-chip (SoC) designers must make tradeoffs between features, performance, power and cost. Enterprise SoC designers have their... » read more

Low-Power Design Is More Than Just Minimizing Power

Engineers are accustomed to making tradeoffs when designing products — faster and more power-hungry, or slower and lower-power; expensive and durable, or cheap and disposable; and so on. The ongoing list of tradeoffs and subsequent choices that need to be made can sometimes appear quite daunting. This blog discusses how the design of electronic systems in the context of power has expanded bey... » read more

How Much Will That Chip Cost?

From the most advanced process nodes to the trailing edge of design there is talk about the skyrocketing cost of developing increasingly complex SoCs. At 16/14nm it’s a combination of multi-patterning, multiple power domains and factoring in physical and proximity effects. At older nodes, it’s the shift to more sophisticated versions of the processes and new tools to work within those proce... » read more

Design Topology Requires Physical Data

By Ann Steffora Mutschler To best understand a design topology and make decisions on clock/register gating, vector sets are required for the RTL tools to understand how to gate clocks and registers. However, if certain constraints are set on all enabled signals in RTL they can be re-used for gating clocks and registers downstream where enablers are not available—even without needing a ... » read more

Optimizing IP For Power

By Ed Sperling As the amount of commercial IP in an SoC increases, the entire bill of materials is coming under increasing scrutiny because of a new concern—power. Commercial IP, after all, is largely a collection of black-box solutions to speed up the time it takes to bring a chip to market, and frequently to improve the quality, but the cumulative impact on the system power budget has neve... » read more
