L-shaped channel wiring method

摘要

To minimize the area of an L-shaped channel wiring region between VLSI circuit blocks, a trunk 1 is formed in the direction along L-shaped sides A and B in the wiring region interposed between the L-shaped sides A and B of circuit blocks CB1 and CB2 having terminals on their sides. The trunk 1 is converted into a polygonal line so as to occupy two tracks. The polygonal line is obtained by combining a line segment in the direction along the L-shaped sides A and B with a line segment parallel to the middle angle direction D of an L-shaped angle.
