Abstract:In this paper, we study the over-the-cell channel routing problem for the cell model in which all the pins are positioned along a horizontal line inside the corresponding cell. We present an efficient approach to the problem under the assumption that two metal layers are available for routing in each of the two over-the-cell regions and three metal layers are available for routing in the channel. The idea of our approach is to treat the three routing regions as a two-layer expanded channel, and to generate a t… Show more
