Data loss: a bit of information (literally: a bit) … 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.
