Patent ID: 8225268

Claim:
A wiring design method for a wiring board, the wiring board comprising first connection terminals and second connection terminals formed on a first surface of the wiring board, the first connection terminals and the second connection terminals being correlated with each other one-to-one, the method comprising: connecting the first connection terminals and the second connection terminals, respectively, on the first surface, by using wirings; and conducting design rule check for the second connection terminals and the wirings, by using an automatic wiring design apparatus; if at least one design rule error is found in an obtained result of the design rule check, selecting one design rule error from the obtained result of the design rule check as a selected design rule error; specifying a predetermined number of the second connection terminals as selected second connection terminals that correspond to the selected design rule error; moving the selected second connection terminals to predetermined coordinate positions on the first surface, respectively, to form several connecting patterns; and for each of connecting patterns, connecting the second connection terminals including the selected second connection terminals and the first connection terminals correlated with the second connection terminals including the selected second connection terminals, respectively, on the first surface, by using wirings; conducting design rule check for the second connection terminals and the wirings; and determining whether neither design rule errors are detected newly nor the selected design rule error is detected.
