ABSTRACT:
A semiconductor layout design apparatus has an inter-block connection information extracting part, a cell initial placement part and an evaluation value. The inter-block connection information extracting part configured to extract the number of wiring connections between a plurality of blocks including standard cells and macrocells based on a net list, library information, floor plan information and technology information. The cell initial placement part configured to initially place the standard cells and the macrocells in an placement region to generate an initial floor plan. The evaluation value calculating part configured to calculate an evaluation value of the floor plan based on distances between a plurality of blocks including the standard cells and the macrocells initially placed by the cell initial placement part and the extracted number of the wiring connections between a plurality of blocks.
