1. A method for determining whether a first rectangle and a second rectangle of an electronic circuit structure overlap, the first rectangle and the second rectangle being aligned along an x-y coordinate system having an x-axis and a y-axis, the method comprising: moving each of the sides of the first rectangle that are parallel to the y-axis to a single point at the center of the first rectangle, the distance that each of the sides that are parallel to the y-axis is moved being an x-difference; moving each of the sides of the first rectangle that are parallel to the x-axis to the single point at the center of the first rectangle, the distance that each of the sides that are parallel to the x-axis is moved being a y-difference; moving each of the sides of the second rectangle that are parallel to the y-axis away from the center of the second rectangle by the x-difference; moving each of the sides of the second rectangle that are parallel to the x-axis away from the center of the second rectangle by the y-difference, resulting in an enlarged rectangle; and determining whether the single point at the center of the first rectangle resides within the enlarged rectangle, thus indicating that the first rectangle and the second rectangle overlap.
