摘要： A method of designing a layout of an integrated circuit includes generating floorplan data by performing floorplan based on input data for the integrated circuit, searching for a path between a first point and a second point, which are specified, the searching based on the floorplan data, and positioning components of the layout based on a result of the searching. The searching for the path includes distinguishing based on the floorplan data a first region where routing is possible from a second region where the routing is not possible, receiving position data on the first point and the second point, and searching for a shortest path between the first point and the second point, on the first region.
