A layout system is described comprising a layout unit configured to layout cells in a mask design for a semiconductor chip based on library cells for a specified process node; a non-critical path determination unit configured to determine a non-critical path in the semiconductor chip; a cell determination unit configured to determine a group of cells in the mask design that form a part of the non-critical path and determine the corresponding library cell for at least one of the group of cells; a library cell modifying unit configured to modify one or more corresponding library cells to form a corresponding modified library cell; and a cell replacement unit configured to replace a library cell in the group of cells in the mask design that form a part of the non-critical path with the corresponding modified library cell.
