Abstract
Distinguishing information that differentiates one portion with a port located on a boundary of a logic layer on a net crossing the logic layer as the boundary from another portion is added to each of the portions (step ST ). Each time a cell forming a specific region of a logic circuit is laid out, a layout of the logic circuit in that region is analyzed, a logic optimization is executed to rewrite the net list of the logic circuit in that region so as not to alter the number of ports located on the boundary of the logic layer by using the distinguishing information, and the layout of the logic circuit in that region is modified on the basis of the rewritten net list (step ST ).
