    摘要: The present invention relates to a method for routing data paths in a semiconductor chip with a plurality of layers. The inventive method comprises the steps of wiring a launching clock path and a receiving clock path on one or more layers according to at least one predetermined condition, performing one or more timing tests for determining any critical paths, and determining a weight function for every layer of each critical path. Said weight function is defined as the difference between a property of the launching clock tree and the same property of the receiving clock tree on said layer. If said weight function is positive for any layer, the wiring of the data path is not allowed on said layer. Preferably the remaining layers are chosen in such a way that a local variation of the delay on said layer is minimal.
