Other AbstractTo obtain a better placement result,a partitioning—based placement algorithm with wirelenIgth prediction calledⅢ一Pl is presented.A new method is proposed to estimate proximity of interconnects in a netlist,which is capable of predicting not only short interconnects but long interconnects accurately.The predicted wirelength is embedded into the partitioning tool of bisection—based global placement,which can guide our placement towards a solution with shorter interconnects.In addition.the timing objective Call be handled within the algorithm by mi。ni。ml。zi‘ng the critical path delay.Experimental resuiLs show that.compared to Capol0.5,mPL6,and NTUplace,l-lJ—Pl outperforms these placers in terms of wirelength and run time. The improvements in terms of average wirelength over Capol0.5,mPL6 and NPUplace are 13%,3%,and 9%with only 19%.9l%,and 99% of their runtime,respectively.By integrating the predicted wirelength—driven clustering into Capol0.5,the placer is able to reduce average wirelength by 3%.The timing—driven HJ—PI can reduce the criticaI path delay by 23%.
