Programmable local clock buffer capable of varying initial settings

A computer program product comprising a computer readable storage medium having a computer readable program, wherein the computer readable program, when executed on a computing device, causes the computing device to:

• receive an integrated circuit design;
• provide a local clock buffer in association with a local portion of the integrated circuit design;
• provide one or more delay circuit paths, the one or more delay circuit paths being selectively connectable to existing circuit paths in the local clock buffer;
• configure the local clock buffer to use one of the existing circuit paths in the local clock buffer to obtain a pre-established initial clock signal characteristic for converting an input clock signal to a local clock signal output;
• and
• selectively connect the existing circuit path used by the local clock buffer to at least one of the one or more delay circuit paths to thereby modify the pre-established initial clock signal characteristic to thereby provide a modified initial clock signal characteristic for the local clock signal output.

A data processing system, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• receive an integrated circuit design;
• provide a local clock buffer in association with a local portion of the integrated circuit design;
• provide one or more delay circuit paths, the one or more delay circuit paths being selectively connectable to existing circuit paths in the local clock buffer;
• configure the local clock buffer to use one of the existing circuit paths in the local clock buffer to obtain a pre-established initial clock signal characteristic for converting an input clock signal to a local clock signal output;
• and
• selectively connect the existing circuit path used by the local clock buffer to at least one of the one or more delay circuit paths to thereby modify the pre-established initial clock signal characteristic to thereby provide a modified initial clock signal characteristic for the local clock signal output.
