Claim 11:
12. A method for synchronizing clocks for an integrated circuit, wherein the integrated circuit comprises a clock source, at least two functional circuits, and at least two clock generators corresponding to the at least two functional circuits; and the method comprises:
generating, by the clock source, a clock signal of the integrated circuit;
determining a clock delay of a corresponding functional circuit based on a transmission distance, over which the clock signal of the integrated circuit is transmitted from the clock source to the corresponding functional circuit, and a load of the corresponding functional circuit; and
determining an initial phase of the corresponding functional circuit based on a clock delay of a reference circuit and the clock delay of the corresponding functional circuit, wherein the reference circuit is one of the at least two functional circuits; and
generating, by each of the clock generators, a clock signal of the corresponding functional circuit based on the clock signal of the integrated circuit and the initial phase of the corresponding functional circuit, so as to keep clock signals of all the functional circuits synchronized.
