WebNov 20, 2024 · The Clock Domain Crossing Problem In digital design there is a requirement to transfer data from one clock domain (source) to another (destination). … WebJan 1, 2011 · A clock crossing between such clocks is known as a synchronous clock domain crossing. It can be divided into several categories based on the phase and frequency relationship of the source and destination clocks as follows: ... However, the data incoherency issue can still be there. In such cases, standard techniques like handshake … 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. onslip 360
