CIRCUIT DESIGN SUPPORT METHOD, COMPUTER PRODUCT, CIRCUIT DESIGN SUPPORT APPARATUS, AND SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

A circuit design support method includes obtaining layout data that indicates positions of a plurality of clock receivers disposed in a circuit and positions of first clock wires disposed in the circuit; and calculating, by a computer, a value corresponding to lengths of wires respectively connecting the clock receivers to second clock wires on the basis of the obtained layout data, the value being calculated for each of a plurality of combinations of a count of the second clock wires and positions of the second clock wires, the second clock wires being disposed in a wiring layer of the circuit and being perpendicular to the first clock wires.
