PROBLEM TO BE SOLVED: To provide a method and device for designing a semiconductor integrated circuit, capable of shortening the design period or facilitating the design. SOLUTION: When the whole chip is divided to a top and a plurality of blocks, and placement and routing of the plurality of blocks are performed (S102 and S104), a block ILM including extracted data belonging to those except the own block and related to signal input and output to the own block (logic data, physical data and RC data) is used. The placement and routing of the blocks using the block ILM is performed in two steps. In one step (S102), for example, a block ILM including RC data based on temporary placement is used, and in the other step (S104), a block ILM including RC data based on actual placement and routing (S102 and S104) is used.
