Abstract
An integrated circuit (IC) design method includes providing a design layout of the IC and placing a first cell and a second cell into the design layout. The second cell is a mirror of the first cell. The method further includes dividing the first cell into a first plurality of segments and dividing the second cell into a second plurality of segments. A third cell is formed by connecting a first portion of the first plurality of segments with a first portion of the second plurality of segments. A fourth cell is formed by connecting a second portion of the first plurality of segments with a second portion of the second plurality of segments. The first, second, third and fourth cells each have substantially the same function.
