发明名称 METHOD FOR SELECTING INTERACTIVE UNCONNECTED NETWORK CORRECTION LAYER OF MULTI-LAYERED WIRING BOARD
摘要 PURPOSE:To speed up the selection and determination of the wiring pair layers of an unconnected network by finding the channel use rate of the wiring area of the unconnected network as to all pair layers, and interactively displaying the wiring area in order from pair layers which are low in channel use rate. CONSTITUTION:An unconnected network start point terminal 11 and an unconnected network end point terminal 12 are present in the unconnected network wiring area 13, and a 3rd pair layer Y-directional electric conductor 14 and a 3rd pair layer X-directional conductor 15 are connected by a veer 16 for 3rd pair layers. Here, parameters required for wiring such as the wiring order and permissible wiring length of all unconnected networks are inputted first, then a normal automatic wiring process is performed; and, remaining unconnected networks which can not be connected eventually are interactively wired. Namely, the channel use rate of the wiring area 13 of each unconnected network is found, it is judged whether or not the wiring process is performed in the order of pair layers which are lower in channel use rate on the assumption of the wiring order of each network, and, in such the way, the wiring process is advanced.
