The Many Flavors Of UPF: Which Is Right For Your Design?
By Madhur Bhargava - 11 Feb, 2021 - Comments: 0

Energy efficient electronic systems require sophisticated power management architectures that present difficult low-power verification challenges. Accellera introduced the Unified Power Format (UPF) standard in 2007 to help engineers deal with these complex issues. To keep pace with the growing complexity of low-power designs, the UPF standard has itself continued to evolve through the relea... » read more

Power Management And Integration Of IPs In SoCs: Part 1
By Progyna Khondkar - 09 Apr, 2020 - Comments: 0

IPs – whether in the form of soft or hard macros – are the epicenter of today’s SoC designs. Integration of IP with low power designs and conducting power aware (PA) verification are always complex and cumbersome. Because most of these IPs are self-contained, pre-verified at the block level, and must be preserved in their totality when integrated or verified at the SoC level. Until UPF... » read more

Power Modeling Standard Released
By Brian Bailey - 14 Aug, 2019 - Comments: 0

Power is becoming a more important aspect of semiconductor design, but without an industry standard for power models, adoption is likely to be slow and fragmented. That is why Si2 and the IEEE decided to do something about it. Back in 2014, the IEEE expanded its interest in power standards with the creation of two new groups IEEE P2415 - Standard for Unified Hardware Abstraction and Layer fo... » read more

Empowering UPF Commands With Effective Elements Lists
By Progyna Khondkar - 16 Jul, 2019 - Comments: 0

The Unified Power Format (UPF) is intended for power management, power aware verification, and low power implementation. The more we explore the inherent features of UPF commands and options, and comprehend their interrelation, the more we become accurate, productive, and consistent in developing UPF for our intended purposes. Although the UPF is very well defined through the IEEE 1801 LRM, ... » read more

What Happened To UPF?
By Brian Bailey - 16 Apr, 2018 - Comments: 1

Two years ago there was a lot of excitement, both within the industry and the standards communities, about rapid advancements that were being made around low-power design, languages and methodologies. Since then, everything has gone quiet. What happened? At the time, it was reported that the [gettech id="31043" comment="IEEE 1801"] committee was the largest active committee within the IEEE. ... » read more

Powerful New Standard
By Brian Bailey - 11 Feb, 2016 - Comments: 0

In December the IEEE released the latest version of the 1801 specification, entitled the IEEE standard for design and verification of low-power integrated circuits. Most people know it as UPF, or the Unified Power Format. That was the name the first version of it held while being developed within Accellera. The standard provides a way to specify the power intent associated with a design, enabli... » read more

UPF-Friendly RTL
By Bernard Murphy - 13 Mar, 2014 - Comments: 0

On a recent customer visit, we were introduced to a new term – new to us at least – “UPF-friendly RTL”. While I hadn’t heard the term, I have been going on about the concept for some time – to the point, no doubt, of becoming terminally boring. We’ve had several customers quietly doing this for years, but now I’m starting to hear it from more customers, and from 1801 committee m... » read more

Unified Power Intent
By Ed Sperling - 01 Mar, 2013 - Comments: 0

The next version of the Unified Power Format has been approved, bridging the major differences between UPF/IEEE 1801 and the Common Power Format. For anyone who works in low-power verification, this is very good news. The new standard is the result of an unprecedented collaboration by chipmakers and EDA companies, and the people who devised a solution to this problem deserve a big pat on the... » read more
