Abstract
A method for designing and making an integrated circuit is described. That method utilizes statistical models of wire segments to accurately estimate the expected length of minimum-length, orthogonal wire segments within a block. From these estimates, the method accurately estimates an ratio between the horizontal and vertical routing resources required, termed the 'H/V Demand Ratio.' From the H/V Demand Ratio, an accurate estimate of the height and width of the block may be determined. Thereafter, placement and routing may be performed quickly and accurately, thereby allowing the block to be designed and manufactured quickly and cost effectively. A method for designing an integrated circuit with efficient metal-1 resource utilization is also described.
