1. Method for matching the lengths a plurality of signal traces which are electrically connected to at least one integrated circuit chip, each of the signal traces including a board trace which is formed on a circuit board and electrically connected to a corresponding package trace formed on the integrated circuit chip, said method comprising:

  • multiplying a length of each of the package traces by a correction factor for the corresponding integrated circuit chip on which the package trace is formed;

    summing a length of each of the board traces and a multiplied length of each of the corresponding package traces;

    subtracting each of the signal traces from a length of a longest signal trace from the plurality of signal traces after the board traces and said multiplied lengths have been summed; and

    , adding a difference in length obtained from said subtraction to a shorter signal trace of said subtraction.
