Abstract: An IC device may include functional regions as well as replica cells and filler cells that can reduce local layout effect in the IC device. A functional region includes functional cells, e.g., logic cell or memory cells. A white space may be between a first functional region and a second functional region. A first portion of the white space may be filled with replica cells, each of which is a replica of a cell in the first functional region. A second portion of the white space may be filled with filler cells that are not functional. The first function region is closer to the replica cells than to the filler cells. A third portion of the white space may be filled with replica cells, each of which is a replica of a cell in the second functional region. The second portion is between the first portion and the third portion.
