    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.

DAC 2016 | Using a Chessboard Challenge to Discover Real-world Formal Techniques

Session Details

In December 2015, Oski challenged formal users to solve a chessboard problem. This was an opportunity to show how nifty formal techniques might be used to solve a fun puzzle. Design verification engineers from a variety of semiconductor companies and research labs participated in the contest. The techniques submitted by participants presented a number of worthy solutions, with varying degrees of success. In all cases, formal techniques were needed fight formal complexity. In this session we describe the puzzle, and some of the techniques, all of which are relevant to real-world ASIC designs. Techniques included case-splitting, symmetry reduction, assume-guarantee and disabling lower proof depths. We will also describe the winning solution.
