INTEGRATED CIRCUIT DESIGN DEVICE, INTEGRATED CIRCUIT DESIGN METHOD AND INTEGRATED CIRCUIT DESIGN PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a new integrated circuit design technology allowing efficient execution of wiring design of a shield-equipped clock wiring line. SOLUTION: This integrated circuit design device has: a storage means storing a list of an identifier of the usable shield-equipped clock wiring, and information about a division rule for describing a division form of the shield-equipped clock wiring indicated by the identifier; a means inputting a wiring layer of the shield-equipped clock wiring performed with a wiring request, the identifier of the shield-equipped clock wiring, and a start point and an end point of the shield-equipped clock wiring; a means specifying the division rule of the shield-equipped clock wiring indicated by the input identifier by referring to the storage means; and a means deciding whether the shield-equipped clock wiring of a division result wherein the division is performed based on the specified division rule is spatially permitted or not in terms of space to decide whether the shield-equipped clock wiring performed with the wiring request is permitted or not.
