1. A printed circuit board layout system, comprising:

  • a first storage unit storing a plurality of function modules; and

    a processor unit executing the plurality of function modules;

    a second storage unit;

    wherein the plurality of function modules comprises;

    a PCB layout module configured to generate PCB files according to input wiring diagrams, and generate polygons and record profile attributes of each of the generated polygons;

    a polygon merging module, comprising;

    an obtaining sub-module configured to obtain profile attributes of selected polygons in one opened PCB file in response to user input and output the profile attributes to the second storage unit;

    a selecting sub-module configured to select two profile attributes each time from the second storage unit; and

    a computing sub-module configured to determine whether two polygons corresponding to the selected profile attributes are overlapping according to the selected profile attributes, and record a new profile attribute describing the shape of a new polygon of a combined shape of the two polygons excluding lines indicating the overlapping portion of the two polygons if the two polygons are overlapping.
