Document Type and Number:
Japanese Patent JP2829075
Kind Code:
B2
Abstract:
PURPOSE:To automatically generate a through hole position by generating throughholes for relay at the positions of wiring patterns having the same coordinate among plural wiring patterns with the same signal names but unconnected. CONSTITUTION:The through-holes for relay are generated at points P1, P2 of single layers and which form endpoints. When the endpoints L1 and L3 exist as in the point P2, the through-hole is generated at, for example, the endopoint L1 on one side, and the endpoints L1 and L3 are connected with each other at the point P2, and when the point P2 of the endpoint L3 is not set as the endpoint, it is not targeted as the generation of the through hole for relay for the endpoint of a line. When the above processing is executed on the wiring patterns L1-L3, L5, the through-holes are generated at the points P1 and P2, and the wiring patterns are connected with the wiring routes 01, L1, L3, L5, and 03. However, the case that the endpoint L2 is not connected in spite of the fact that the same signal name ABC-P as that on the wiring routes 01, 03 is attached on wiring routes 02, 04 occurs. Then, the through-hole for relay is generated at the point 3 if the same coordinate exists among the wiring patterns.
