ABSTRACT
IEEE 1801 UPF [1] enables early specification of “power intent”, or the power management architecture of a design, so that power management can be taken into account during design verification and verified along with design functionality. The verified power intent then serves as a golden reference for the implementation flow. To fully realize the advantages of this capability, a methodology called Successive Refinement was conceived during development of IEEE 1801-2009 UPF. However, this methodology is still not well understood in the industry.
In this article, we present the UPF Successive Refinement methodology in detail. We explain how
