在多电源多电压的时代符合UPF单元库／环境

各式各样的低功耗设计技术需要被使用来降低设备的功耗，进而增加电池的使用寿命。芯片设计的每个步骤都需要低功耗方案，如何有效地设计与管理这些复杂的低功耗方案成为了一个至关重要的课题。本文我们将回顾传统多电源多电压设计流程，然后与基于统一功率格式方法学做一个比较。稍后，我们将介绍专用单元库的需求以及分享一些我们对统一功率格式方法学的看法。

UPF-Compliant Library/Environment in the Multi-Supply Multi-Voltage Era

While various low power design techniques need to be employed to reduce device power consumption and increase battery lifetime, howto efficiently design and manage these complex lowpower schemes intertwined with chip design activities becomes a major concern. In this paper, we will review traditional MSMV library environment, then compare it with Unified Power Format- based methodology. Later, we will introduce specific library requirements and share some views on UPF- based methodology.
