A circuit and a method of layout-designing a circuit based on circuit information. The method includes generating layout information including a core region based on the circuit information, laying out an I/O circuit in a region other than the core region on the layout information based on the circuit information, determining a layout-permitted region of pads, which is included in regions other than the core region and a layout region of said I/O circuit, based on circuit information, and laying out the pads in the layout-permitted region.
