Abstract: A high-level low power scheduling method for multiple supply voltages is proposed，which is constrained under time and resource.By means of Lagrange multiplier method，this method distributes the slack to the operator nodes in the data path，thus，efficiently reduces the energy consumption of design circuit.In the process of scheduling and adjusting，the operator nodes both in critical path and non-critical path can be dealt simultaneously.The feasibility of this method for power optimization is demonstrated by experimental results.
