COMPONENT FOR TERMINAL EXTENSION, USED FOR TERMINAL LAYER SETTING OF SEMICONDUCTOR CIRCUIT HAVING PLURALITY OF WIRING LAYERS

摘要

PROBLEM TO BE SOLVED: To provide a terminal layer-setting method that can avoid an increase in delay time of cells or macros mounted on a substrate and set a wiring layer (terminal layer) as an extension destination of a cell or macro. SOLUTION: The terminal layer-setting method in which a computer sets a terminal layer of a semiconductor circuit having a plurality of wiring layers includes: constituting a semiconductor circuit; acquiring various information such as arrangement information related to the plurality of cells or macros mounted on the substrate from a storage means of the computer; comparing driving capability of a target cell or macro included in the acquired information with the resistance value of wiring for connecting the target cell or macro to a cell or macro as a connection destination; and setting the terminal layer being the wiring layer as an extension destination of a wiring terminal of the target cell or macro on the basis of the result of the comparison.
