System and method for automatic deskew across a high speed, parallel interconnection

1. Field of the Invention A method and system performs automatic deskew tuning and alignment across high-speed, parallel interconnections in a high performance digital system to compensate for inter-bit skew. Rather than using a VDL, digital elements such as registers and multiplexers are used for performing the automatic deskew tuning and alignment procedure. The result is a simpler, more robust deskew system capable of operating over a wider range of input values with greater accuracy and over a broader range of temperatures. In addition, the method and apparatus performs a one to four unfolding of the signal on each interconnection. The system includes a deskew controller and a plurality deskew subsystems. The deskew controller computes the amount of delay needed to correct the skew on each interconnection and feeds a different (or appropriate) delay value to each deskew subsystem located at the receiving end of each interconnection.
