Abstract
A method includes placing, in a layout, a plurality of first cells each having a first NFET fin number. The first cells are swapped with a plurality of second cells each having a second NFET fin number less than the first NFET fin number. After swapping the first cells with the second cells, a timing critical path in the layout is identified. Some of the second cells in the identified timing critical path are swapped with a plurality of third cells each having a third NFET fin number greater than the second NFET fin number. After swapping some of the second cells in the identified timing critical path with the third cells, an integrated circuit is fabricated based on the layout.
