Abstract

In this paper, we study the relationship between netlist structure and the efficiency of placers measured in terms of quality and stability of results. We analyze three types of placers: analytic, simulated-annealing-based and partition-based. We test the placers on industrial and synthetic benchmarks. Based on the observations and analyses of experimental results, we obtain several useful conclusions about relationships between netlist structure and placement efficiency of different types of placers.
