ABSTRACT:
A method of simplifying the layout of a printed circuit board is disclosed that enables an integrated circuit to modify—after the integrated circuit is manufactured—which pads transport which signals. An integrated circuit in accordance with the illustrative embodiment comprises a two-dimensional array of pads. At the time that the integrated circuit is designed, some or all of the pads are assigned to one or more “transposition groups.” One or more pads are included in a transposition group when, for example, it might be necessary or advantageous to transpose the signals carried by those pads after the integrated circuit has been manufactured. One or more of these transpositions can, for example, greatly simplify the layout of a printed circuit board.
