<p><P>PROBLEM TO BE SOLVED: To provide a printed circuit board having a wiring length in equal length without using zigzag wiring, etc. when bus wiring are branched and connected from one IC to a plurality of ICs. <P>SOLUTION: When a first IC and a plurality of second ICs are connected by branching the bus wiring by using a via, etc., the bus wiring is branched to two sets of bus wiring at a branching position, line symmetrically drawn from the branching position toward the second ICs so that the lengths of all the wiring in the bus wiring are formed in equal length. The branching position of each wiring of the bus wiring is made equal to the first IC so that the wiring length of each wiring after branching and the wiring length of each wiring before branching are made equal. <P>COPYRIGHT: (C)2004,JPO</p> |
