System and method for removing T-point elements with unused stubs from a PCB layout design

A storage medium having stored thereon instructions that, when executed by a processor of a computer, causes the processor to perform a 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.

A computing system for removing T-point elements with unused stubs from a printed circuit board (PCB) layout design using software of a computer, comprising:

• a storage device;
• at least one processor;
• and
• one or more programs stored in the storage device and being executable by the at least one processor, the one or more programs comprising:
• an obtaining module operable to obtain each signal line of the PCB layout design from the storage device, wherein each said obtained signal line comprises one or more T-point elements with unused stubs;
• a dividing module operable to divide each said obtained signal line into a plurality of lines according to the one or more T-point elements with unused stubs, and obtain properties of each of the plurality of lines without properties of the T-point elements with unused stubs;
• a reconnecting module operable to delete, in the PCB layout design, each signal line comprising one or more T-point elements with unused stubs and reconnect the plurality of lines according to the properties of each of the plurality of lines, and generate a reconnected signal line thereby removing the one or more T-point elements with unused stubs in each said obtained signal line;
• and
• an outputting module operable to output the reconnected signal line on a display device of the computer.
