1. A method of designing a semiconductor integrated circuit, comprising the steps of:

  • laying out a plurality of programmable logic cells each having storage elements and each capable for outputting an arbitrary logic output corresponding to an input according to information stored in each storage element so as to spread over an entire semiconductor chip;

    thereafter determining a layout of circuit blocks each having a desired function; and

    laying out each of said circuit blocks in a layout-determined area on the semiconductor chip by deleting said programmable logic cells in said layout-determined area and placing said circuit blocks there into.
