Low Power Coalition

Low Power Coalition:
Advances in Low Power Design

The Low Power Coalition (LPC) of Si2 is responsible for the development of standards and enabling materials to support low power design by taking a flow-centric view from ESL to GDSII. It has defined and published 3 versions of the Common Power Format (CPF Specs) standard - v1.0 in March, 2007, v1.1 in September, 2008, and CPF 2.0, published in February 2011 (CPF Specs) - that allows a designer to express power constraints and semantics in a clear and concise manner. The LPC has published a power-aware reference flow that is recommended to the industry, including the identification of power closure points and other related information available throughout the flow, from Electronic System Level (ESL) through detailed implementation (Power Aware Closure Flow). This flow was used to define the High Level Power Modeling Requirements Documents version 1.0 and 1.1 (downloads). The power modeling requirements have been proposed to the Liberty Technical Advisory Board (LTAB) as enhancements to aid in power modeling structures. Work continues to extend CPF into the systems level for the next release and the power modeling work moves forward to support systems level power characterization and analysis. The Low Power Coalition has also published Parsers, Pocket Guides(CPF 1.0, CPF 1.1), Interoperability Guidelines for CPF 1.1 and CPF 2.0 and many other helpful documents for Low Power design. Please contact Bob Carver for more information about joining the Low Power Coalition.
