Power Intent Standards

Power Intent Standards
Over the last few years, the industry has adopted either of two leading formats for specifying power intent ―the Unified Power Format (UPF) and the Common Power Format (CPF)―for power intent specification. Accellera and the Silicon Integration Initiative (Si2) released UPF 1.0 and CPF 1.0 specifications, respectively, in early 2007 based on technical contributions from member companies. In 2008, UPF was handed over to the IEEE P1801 working group, who released the IEEE 1801-2009 standard, colloquially known as UPF 2.0, in March 2009. Meanwhile, the Low Power Coalition (LPC) of Si2 released the CPF 1.1 specification in September 2008 and CPF 2.0 in February 2011.
Si2’s contribution of the Open Low-Power Methodology (OpenLPM) to IEEE, announced in May 2011, is a milestone in the development of power format standards and the most promising path yet for the industry to converge on one power format. Methodology convergence, however, is a pre-requisite for power format convergence.
