这是FILL1的版图和库中的描述:
The library contains several FILL cells: FILL1, FILL2, FILL4, FILL8, FILL16,FILL32, FILL64. The number appended to "FILL" in the cell name denotes the width of the cell in tracks.
During place and route, the FILL cells are used to connect power and ground rails across an area containing no cells. The FILL cells are also used to ensure gaps do not occur between well or implant layers which could cause design rule violations. Using wider cells where appropriate reduces the size of the layout database.
