The UPF is the ultimate abstraction of low power methodologies today. It provides the concepts and the artifacts of power management architecture, power aware verification and low power implementation for any design. Although UPF is very well defined through IEEE 1801 LRM, it is often difficult to comprehend many primitive and inherent features of individual UPF commands-options or relations between different varieties of UPF commands-options. The semantic context between most of the UPF commands are orthogonal. However, fundamental constituent parts of UPF that buildup the power management architecture are inherently linked because of their transitive nature — specifically the UPF commands that establish the links with DUT objects; like
