This manual and error-prone process has become increasingly CDC-clean? As the design and its corresponding constraints evolve, some paths that are considered to be synchronous and timed using static timing analysis may be incorrectly interpreted as a SpyGlass-CDC helped to identify some additional clock and.
About a decade ago, semiconductor designs had just a few asynchronous clocks which were easily managed by designers through the process of manual design reviews. The situation today is completely different. An SoC can have hundreds of asynchronous clocks, driving different complex functions,

Besides the traditional CDC issues, Reset Domain Crossing (RDC) issues can also cause metastability in signals. Use of asynchronous resets is becoming more prevalent because of the wider use of multiphase power-up/boot sequences, etc. As a consequence, RDC issues are causing more and more design errors.
14 Sep 2006 Hi, Atrenta Spyglass has the good solution for CDC issues, it will report,suggests and give the kind of crossing information based on the selected rules. For details and documentation you can visit www.atrenta.com. -- Regards Satya.A

What is Clock Domain Crossing (CDC) The Problem ? The trend Leads to Chip Failure .no software fix.. How CDC Issues look like And recommendations around them Special case CDC Issues Design is CDC OK but Silicon has issues ?? Different flows available (with Atrenta Spyglass) when to use
