ABSTRACT:
A method of designing a semiconductor device is provided. According to the method, a group of cells that is a target of clock distribution is placed. After the group of cells is placed, a plurality of clock driver cells for driving the clock are placed such that each clock driver cell is prohibited from overlapping with a prohibited region of a predetermined size surrounding another clock driver cell.
