PROBLEM TO BE SOLVED: To provide an integrated circuit layout designing device capable of improving the operation frequency of an LSI. SOLUTION: A floor plan inputting/deciding means 1 inputs physical library information, connection information between groups and the size of each group and decides a floor plan. An inter-group wiring means 2 allows each inter-group wiring to pass an inter-group area according to the floor plan and performs wiring. A relay buffer inserting means 3 refers to wiring between the groups and the signal flow of the inter-group wiring and inserts a relay buffer. A logical circuit changing means 4 adds and corrects the inserted relay buffer to intra-group/inter-group logical connection information. An intra-group logical circuit arrangement wiring means 5 gives an arrangement position constraint to the inserted relay buffer, gives a wiring length constraint to wiring passing in a group and performs the arrangement and wiring of a logical circuit in the group.
