1. A method of compensating for skew in a distributed clock signal to a domain clock, comprising:

  • comparing the distributed clock signal at a first location in the processor with a reference clock signal;

    determining delay control bits based on the results of said comparison said, delay control bits including fuse bits and non-fuse bits;

    storing said delay control bits in a control register;

    decoding said fuse bits;

    programming a programmable delay compensator according to said fuse bits;

    adjusting the distributed clock signal based on said delay compensator and said non-fuse bits.
