A novel power optimization methodology for reducing the dynamic power consumed by the routing of FPGA circuits by modifying the constraints applied to existing commercial tool sets is presented. The power optimization techniques influence commercial FPGA Place and Route PAR tools by translating power goals into standard throughput and placement-based constraints. The Low-Power Intelligent Tool Environment LITE is presented which was developed to support the experimentation of power models and power optimization algorithms. The generated constraints seek to implement one of four power optimization approaches slack minimization clock tree paring N-terminal net colocation and area minimization. In an experimental study we optimize dynamic power of circuits mapped into pm Xilinx Virtex-II FPGAs. Results show that several optimization algorithms can be combined on a single design and power is reduced by up to with an average power savings of . Copyright 2006 Li Wang et al.

INTRODUCTION Field-programmable gate arrays FPGAs now handle most digital signal processing functions in an embedded platform. However many embedded platforms such as handheld devices distributed sensors and satellites demand low power in order to increase their functional .
