Nowdays, Low-power design, especially Multi-voltage design becomes a popular and efficient way to reduce both dynamic power and static power. In this paper, we propose an efficient method of level-shifter floorplanning for a given multi-voltage design. This method is a two stage optimization method. First, for a given voltage island and its sequence pair representation, we greedily pre-place level-shifters into white-spaces of multi-voltage island based sequence-pair representation. Then, we employ a modified IARFP  algorithm to re-optimize the positions of level-shifters. Experimental results show that, the proposed two stage level-shifter floorplanner is efficient for post multi-voltage island optimization.
