The placement model and its nonlinear placement solver for VLSI global placement

Jianli Chen, Xiuhua Chen, Wenxing Zhu

Abstract


Ignoring some cell overlaps, global placement computes the best position for each cell to minimize the wirelength. It is a crucial step in very large scale integration (VLSI) physical design, because it affects routability, performance, and power consumption of a design. With the placement model, we develop a nonlinear placement solver to solve the VLSI global placement problem. The proposed method is tested on the IBM standard cell benchmark circuits. Experimental results show that it obtains high-quality results in a reasonable running time.
