A method of designing a double patterning mask set for a layout of a chip includes designing standard cells. In each of the standard cells, all left-boundary patterns are assigned with one of a first indicator and a second indicator, and all right-boundary patterns are assigned with an additional one of the first indicator and the second indicator. The method further includes placing the standard cells in a row of the layout of the chip. Starting from one of the standard cells in the row, indicator changes to the standard cells are propagated throughout the row. All patterns in the standard cells having the first indicator are transferred to a first mask of the double patterning mask set. All patterns in the standard cells having the second indicator are transferred to a second mask of the double patterning mask set.
