1. A method of integrated circuit design, said method comprising the steps of:
- a) identifying critical paths in an integrated circuit design;
b) weighting edges in identified said critical paths c) assigning net criticality to each weighted edge responsive to edge weight; and
d) re-placing and wiring nets according to edge criticality.

Abstract
A method of integrated circuit design and a circuit design tool. Critical paths are identified in an integrated circuit design. Identified edges are weighted. Edges are assigned a higher weight responsive to the number of critical paths in which they are included. A net criticality is assigned to each weighted edge based upon the edge'"'"'s weight. Cells are re-placed and wired according to net criticality.
