July 24, 2013 // By Ping Yeung, Mentor graphics

We will describe a few common CDC violations and the techniques used to determine whether they are real design issues or not. Finally, we will summarize and highlight the results of applying this methodology to a few designs. Check out the white paper to learn more.

With the number of clock domains increasing in today's complex ASIC designs, the ability to thoroughly verify clock domain crossings (CDC) has become even more important. As in functional verification, to ensure CDC issues are thoroughly verified, a comprehensive test plan is essential. Based on our experience working with many customers, we developed a five-step planning process for CDC verification.
