UPF 3.0 is Now Official

The new UPF 3.0 standard offers additional enhancements to address and describe power intent of complex systems on chip (SoCs).

By Lawrence Neukom, Verific Design Automation, Jan. 14, 2016 – 

The Unified Power Format (UPF) 3.0, officially known as IEEE Standard 1801-2015, was approved by the IEEE in December 2015 and will be ready for distribution early this year. Like its predecessors, the standard will be available free of charge through a grant from Accellera, the Electronic Design Automation (EDA) and semiconductor industry's standards organization.

It's been almost nine years since UPF 1.0 was introduced in 2007. Since then, three major UPF revisions have been published. Unfortunately, EDA companies have been lagging with their UPF support. This lack of feature support affects how UPF is being written, preventing designers from using the latest features.

The new 3.0 standard offers additional enhancements to address and describe power intent of complex systems on chip (SoCs). Features include enhanced power state and transitions support, system-level power support, a new information model and programming interface, as well as bottom-up flow support. Eleven new UPF commands were introduced in this version.
