Guiding global placement with wire density
—This paper presents an efficient technique for the estimation of the routed wirelength during global placement using the wire density of the net. The proposed method identifies congested regions of the chip and incorporates the model of the routed wirelength into the objective function in order to effectively alleviate these regions from congestion. The method is integrated in the analytical placement framework and the two-level structure improves the scalability of the placer and speeds up the algorithm. The proposed analytical placer provides the best-so-far average routed wirelength in the IBM version2 benchmark suite.
