Patent ID: 8146048

Claim:
A computer-implemented method for removing T-point elements with unused stubs from a printed circuit board (PCB) layout design using software of a computer, the method comprising: (a) obtaining each signal line of the PCB layout design from a storage device of the computer, wherein each said obtained signal line comprises one or more T-point elements with unused stubs; (b) dividing each said obtained signal line into a plurality of lines according to the one or more T-point elements with unused stubs, and obtaining properties of each of the plurality of lines without properties of the T-point elements with unused stubs; (c) deleting, in the PCB layout design, each signal line comprising one or more T-point elements with unused stubs and reconnecting the plurality of lines according to the properties of each of the plurality of lines, and generating a reconnected signal line thereby removing the one or more T-point elements with unused stubs in each said obtained signal line; and (d) outputting the reconnected signal line on a display device of the computer.
