DEVICE, METHOD, AND PROGRAM FOR DESIGNING SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To make a loop check on circuit constitution of an arbitrary internal layer of a multi-layered substrate. SOLUTION: A loop check circuit 5 judges whether or not a loop circuit is present as to all layers present in the stage where a specified layer is manufactured. A wiring guide part 6 guides wires around components (DUT) forming a loop circuit to avoid forming the loop circuit when the loop circuit is present in all layers present at the stage where the specified layer is manufactured. A presentation control part 8 specifies the guided result to the designer and urges an operator to decide whether or not the guided result is reflected on a wiring pattern. A guide wire processing part 7 reflects the guided result on the wiring pattern when the operator agrees with the guided result. COPYRIGHT: (C)2006,JPO&NCIPI
