METHOD FOR SUPPORTING WIRING FOR UNWIRED SECTION

摘要

PURPOSE:To rapidly find a route possible to wire an unwired section by dividing a layer into rectangular blocks in each layer, and finding the block having a null wiring track part from one end to the other end of the block. CONSTITUTION:The layer in which a wiring track to perform wiring in a direction of X is assumed and the layer in which the wiring track to perform the wiring in a direction of Y is assumed on a printed board on which an electric circuit pattern is wired are formed as one pair. Next, the layer is divided into rectangular blocks including plural wiring tracks at every layer, and the block possible to be wired having the null wiring tracks more than one wiring track from one end to the other end of the block out of all blocks is found from decided wiring pattern information. The route to connect the unwired section by a wirable block is retrieved, and a rough wiring route is found, then, outputted.
