Considering routability issue in the early stages of VLSI design flow can avoid generating an unroutable design. Several recent routablity-driven placers [8--11] adopt a built-in global router to estimate routing congestion. While the routability of the ...
A new routing algorithm is presented. It is based on a multiple star net model, force-directed placement and maze searching techniques. The algorithm inherits the power of maze routing in that it is able to route complex layouts with various ...
The availability of multiple metal layers in modern IC processes raises the possibility of using non-Manhattan routing on some of the layers in order to reduce the average interconnect length, and thus improve performance and routability. In this paper, ...
