Abstract
A method, apparatus, and recording medium including computer instructions for estimating the size of a core section of a semiconductor integrated circuit are provided. The method includes calculating a total net length of wires of nets and usable channel length of the core section by referring to circuit information and a layout parameter that are used to design the semiconductor integrated circuit. The method includes determining a size of the core section that satisfies conditions based on total net length and usable channel length.
