Abstract :
In this paper, based on the properties of a hexagonal array for flip-chip designs, a generalized hexagonal array, called alpha -hexagonal array, is proposed to increase the I/O density and reduce the area cost on total routing area. Furthermore, based on the angle assignment for the number of wires through any horizontal channel in alpha-hexagonal array, an efficient column-by-column escape routing strategy is proposed for the proposed a-hexagonal array.
