METHOD, PROGRAM, AND APPARATUS FOR DESIGNING SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To efficiently suppress characteristic variations of semiconductor devices.SOLUTION: A semiconductor device design apparatus includes: a storage unit 1 that stores layout parameters that are indexes of characteristic variations according to a layout pattern, for each of a plurality of macros; a macro arrangement unit 2 that automatically arranges the plurality of macros on a semiconductor chip during a floor plan process; a cost calculation unit 3 that calculates a cost indicating the degree of characteristic variations between adjacent macros out of the arranged plurality of macros, on the basis of the stored layout parameters of the plurality of macros; and a macro rearrangement unit 4 that rearranges any of the adjacent macros on the basis of the calculated cost.
