Abstract: A layout method is provided. The layout method may include placing first and second standard cells from a standard cell library, interconnecting the placed standard cells to generate a layout draft, confirming placement and routing at a boundary region between the interconnected standard cells, and revising the layout draft based on the confirmation. Each of the standard cells includes, in part, a conductive line that extends in the first direction and is interconnected to an adjacent standard cell through a source/drain via. To confirm the placement and routing, a first spaced distance from a tip of one of the conductive lines to a tip of the other conductive line, and a second spaced distance from the tip of the first conductive line to the cell boundary are compared with preset threshold values. Revising the layout draft may include adjusting a tip position of one of the conductive lines.
