摘要:
A method for transferring data across different clock domains is provided. The method initiates with detecting a transition of a first clock cycle. The method includes propagating a value associated with the transition of the first clock cycle according to a second clock cycle. The propagation of the value causes a delay of a signal configured to trigger transfer of the data to a logic region operating at the second clock cycle. An interfacing circuit and a programmable logic device are also provided.
