Under the number IEEE 1801, the IEEE has approved the Standard for Design and Verification of Low Power Integrated Circuits. Also known as Unified Power Format 2.0 (UPF 2.0), the standard was developed by Accellera and currently carries the support of multiple vendors and is in use worldwide.
Reportedly, this is the first time that UPF has undergone an IEEE standardization effort. The low-power standard provides portability of low-power design specifications that can be used with a variety of commercial products throughout an electronic system design, analysis, verification, and implementation flow.
Enhancements to UPF 2.0 in the IEEE 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.
