The use of white space in fixed-die standard-cell placement is an effective way to improve routability. In this paper, we present a white space allocation approach that dynamically assigns white space according to the congestion distribution of the placement. In the top-down placement flow, white space is assigned to congested regions using a smooth allocating function. A post allocation optimization step is taken to further improve placement quality. Experimental results show that the proposed… Expand
