Abstract The target of placement problem is related to the wire length, and the time delay optimization is also related to it. But in placement stage, it has not finished final routing, and must be decided without any wire routing whether a kind of placement is good or not, there must have a simple and accurate estimation method of wire net length to evaluate wire length. This paper introduces some kinds of conventional methods which are used to evaluate the wire length, then a new method using fractal to evaluate the wire length is given.
