In the FPGA space, the number of interacting asynchronous clock domains has increased dramatically. It is normal to have not hundreds, but over a thousand clock domains interactions. WebData Incoherency Problem. As seen in the previous section whenever new data is generated in the source clock domain, it may take 1 or more destination clock cycles to capture it, depending on the arrival time of active clock edges. ...
