The Institute of Electrical and Electronics Engineers (IEEE) has approved a new standard that provides portability for low-power design specifications that can be used throughout the electronic system design, analysis, verification and implementation flow.

The spec can also be used to design a variety of commercial products, proponents said.

The IEEE 1801 "Standard for Design and Verification of Low Power Integrated Circuits," also known as Unified Power Format (UPF) 2.0, was first developed by the Accellera, the electronics industry organization focused on EDA standards.

"Industry acceptance of the IEEE 1801 standard power format can help optimize the energy consumption of future electronic systems by enabling engineers and tools to characterize and improve semiconductor power usage much earlier in the design cycle," Acellera chairman Shrenik Mehta said in a statement.

"This version enhances portability by addressing bugs and ambiguities in the UPF 1.0 specification and also delivers new functionality requested by the community of low-power designers," said Stephen Bailey, chairman of the P1801 Working Group.

Enhancements to UPF embedded in the new standard include: support for bias supplies (N-Well, P-well, Deep-N-Well and Deep-P-Well); greater flexibility and capabilities in specification of power states; and enhanced semantic capabilities for merged power domains.

Accellera standards are submitted to the IEEE for formalization and ongoing change control.
