Patent ID: 7802208

Claim:
A method comprising: providing N pins to couple together using a net; by a computer, finding a rectangular route region, comprising the N pins, having a length greater than a width, wherein the length is in a first direction and the width is a second direction, orthogonal to the first direction, the rectangular route area is bounded by a first, second, third, and fourth side of the rectangular route area, the third side is opposite of the first side, the fourth side is opposite of the second side, the first side is longer than the second side, the first and third sides extend in the first direction, the second and fourth sides extend in the second direction; in the rectangular route region, placing a first spine interconnect extending in the first direction at a position in the second direction from the first or third side of the rectangular route area based on a quotient of a sum of the positions of the N pins in the second direction and N; and in the rectangular route region, routing N stitching interconnects in the second direction to couple each of the N pins to the first spine interconnect.
