WebThe CDC rules verify crossings between asynchronous clock domains. Crossings are verified against having combinational logic, convergence, or divergence. It is also checked, that a valid synchronizer is present on the crossing. For the asynchronous resets, de-assertion is verified to be synchronous with the proper clock.

WebSep 25, 2012 · Thus, clock domain crossings (CDCs) are an integral part of any SoC. The main problems which can occur in a clock domain crossing are metastability, data loss and data incoherency. In this paper, all these issues for different types of synchronous and asynchronous clock domain crossings are discussed.
