    The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification. Each course consists of multiple sessions—allowing the participant to pick and choose specific topics of interest, as well as revisit any specific topics for future reference. After completing a specific course, the participant should be armed with enough knowledge to then understand the necessary steps required for maturing their own organization’s skills and infrastructure on the specific topic of interest. The Verification Academy will provide you with a unique opportunity to develop an understanding of how to mature your organization’s processes so that you can then reap the benefits that advanced functional verification offers.

DVCon US 2015 Poster Paper - Successive Refinement: A Methodology for Incremental Specification of Power Intent

Session Details

IEEE 1801 UPF 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 paper, we present the UPF Successive Refinement methodology in detail. We explain how power management constraints can be specified for IP blocks to ensure correct usage in a power-managed system. We explain how a system's power management architecture can be specified in a technology-independent manner and verified abstractly, before implementation. We also explain how implementation information can be added later. Finally, we explain the benefits of Successive Refinement.
