1. A design method for a semiconductor integrated circuit comprising:

  • a first weight determination step of first receiving timing information and connection information (hereinafter referred to as a net listing), and of then performing a weighting calculation process during which a movement range for a cell becomes smaller as the weighting for the cell becomes greater, while weighting is significantly enhanced for a cell for which the timing margin is small; and

    a cell placement step of placing a cell in accordance with weighting results obtained at the first weight determination step.
