AUTOMATIC WIRING DEVICE IN DESIGNING SEMICONDUCTOR INTEGRATED CIRCUIT

PURPOSE:To divide a shortest-distance wiring path in a short time in an automatic wiring design. CONSTITUTION:The positions of the X-coordinates of all partial wiring paths ar1, ar2..., by1, by2..., ayr2, byr2, ayr3 and byr3 are determined on the basis of the positions of the coordinates of each signal terminal and the locations of the coordinates of each channel wiring region of each line. The locations of the Y-coordinates of all partial wiring paths ax1-2-3, bx1-2-r3, axr2-4-r3, bxr2-r3, axr3-5-6 and bxr3-3-4 are determined on the basis of the positional relationship of each partial wiring path extended in the Y-direction in each inter-line wiring region. Accordingly, wiring paths WA, WB tying the signal terminals of each pair in a network shape at a shortest overall distance is decided.
