Abstract
Embodiments of the present application provide a method and an apparatus for adjusting metal wiring density. By detecting metal wiring density in each of metal density detection windows in a target layout, a region in which the metal wiring density is greater than a preset density threshold can be quickly positioned in the target layout, thereby improving the layout correction efficiency; then a power fill mesh in a target metal density detection window in which the metal wiring density is greater than the preset density threshold is cropped multiple times, until the metal wiring density in each of the metal density detection windows is less than or equal to the preset density threshold, such that sufficient power fill meshes are retained in the target layout while the metal wiring density of the target layout is less than or equal to the preset density threshold.
