Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: In addition to wirelength, modern placers need to consider various constraints such as preplaced blocks and density.  propose a high-quality analytical placement algorithm considering wirelength, preplaced blocks, and density based on the log-sum-exp wirelength model proposed by Naylor et al. (2001) and the multilevel framework. To handle preplaced blocks,  use a two-stage smoothing technique, Gaussian smoothing follod by level smoothing, to facilitate block spreading during global placement. The density is controlled by white-space re-allocation using partitioning and cut-line shifting during global placement and cell sliding during detailed placement.  further use the conjugate gradient method with dynamic step-size control to speed up the global placement and macro shifting to find better macro positions. Experimental results show that our placer obtains the best published results
