The main challenges of Godson-2G physical implementation include nanometer process technology effects, high performance design targets, and tight schedule. This paper describes the key innovative features of physical design methodology which had been used in Godson-2G physical implementation, with particular emphasis on interconnect driven floorplan generation （ICD-FP）, adapted boundary constraints design optimization （ABC-OPT）, automatic register group clock tree generation methodology （ARG-CTS）.展开更多
