Abstract:
1. A method for implementing a circuit design for an integrated circuit, the method comprising: (a) obtaining a first wiring to satisfy a given operating frequency; (b) calculating a maximum bypass wiring length based on the given operating frequency and a critical path of the first wiring; (c) obtaining a second wiring by bypassing the first wiring using wires other than wires of the first wiring in a first wiring group including the first wiring, wherein wiring of the integrated circuit is categorized into a plurality of wiring groups, and the first wiring is included in the first wiring group of the categorized wiring groups; and (d) replacing, using a computer, the first wiring with the second wiring, if a difference between the second wiring and the first wiring is not larger than the maximum bypass wiring length, and not replacing the first wiring with the second wiring if said difference is larger than the maximum bypass wiring length.
