ABSTRACT:
A floor-planning system of the present invention prepares a block diagram showing blocks and the connection status among the blocks. The floor-planning system inputs a block diagram, estimates the block sizes, and estimates the aspect ratio range possible for the blocks. The system refers to the estimated block sizes and the estimated aspect ratios to specify the shapes and the arrangement of the blocks in the layout area. The system displays the block arrangement and the connection status among the blocks. The block layout is stored as layout data and utilized in feasibility judgment for a layout area on an LSI or a PCB.
