Abstract

MSV is one of the effective methods to reduce SoC power consumption. In order to facilitate the placement of power supply pins of each voltage island, this paper proposed a multi-voltage floorplanning algorithm considering voltage island boundary constraints. Firstly, based on the representation characteristics of slicing tree, this paper proposed a boundary checking algorithm to quickly determine the boundary information of all modules. Then, in order to minimize the power consumption, this paper used the improved dynamic programming method to assign voltage to each module and construct voltage islands. Finally, it took simulated annealing algorithm as search engine to optimize the chip area, wire length and power consumption simultaneously. In addition, to reduce iteration times, the SA algorithm adopted a two-stage cooling strategy. Experimental results on GSRC circuits show that the proposed algorithm can generate multi-voltage floorplan satisfying boundary constraints, and the power consumption increases only by 5.2% on average compared with that without considering boundary constraints.
