<p>PURPOSE:To guarantee a clock skew after a layout operation and to eliminate the burden of an allocation with reference to an internal clock buffer cell for an internal cell regarding the manufacturing method of an integrated circuit which is constituted by installing the internal cell requiring a clock such as a flip-flop or the like. CONSTITUTION:A logic designing operation is performed by using an internal clock buffer cell 9 which is formed by storing the number of clock buffers 1,1, 112,..., 1115 which are required to drive all of internal cells 101, 102,... 1015 as internal clock buffer cells.</p> |
