A memory write interface in an integrated circuit (IC) and method of providing the same are described. An aspect relates to an apparatus for providing an input/output (IO) interface in a programmable device. The apparatus can include: a memory write interface configured to drive a memory having a daisy-chained clock, a first interface configured to receive output data from the programmable device and a second interface configured to control transmission of the output data to the memory by an IO element of the programmable device, the first interface operating according to a global clock of the programmable device and the second interface operating according to a local clock used only by the IO interface; a delay circuit configured to add a delay to the local clock with respect to the global clock; and a configuration circuit configured to adjust the delay added to the local clock to implement write-leveling at the memory. |
