Apparatus, method, and program for predicting layout wiring congestion

摘要

A layout-wiring-congestion prediction apparatus. The layout-wiring-congestion prediction apparatus includes: a circuit-data providing section providing circuit data; a conversion processing section converting the provided circuit data into directed graph data; a node-placement-coordinate calculation processing section calculating individual node placement coordinates of the directed graph data produced by the conversion processing section; a node-placement-density calculation section calculating a node-placement density on the basis of the individual node placement coordinates calculated by the node-placement-coordinate calculation processing section; and a node-placement-density error determination processing section determining the node-placement density calculated by the node-placement-density calculation section to be an error if the node-placement density is higher than an error-determination threshold value.
