The optimization method comprises the following steps of: assigning positions of information of a gate-level circuit network table, simulation excitation, a unit library and a device model, reading the information in to execute the gate-level circuit simulation, partitioning gate-level circuits, executing circuit analysis and simulation result analysis, and executing optimization processing on the circuits according to the analysis results based on low-power-consumption technologies. According to the optimization method disclosed by the invention, the design of the gate-level circuit network table is optimized, and a part of units are inserted and / or replaced in the circuit network table to support the low-power-consumption technologies of an MTCMOS (Multi-threshold Complementary Metal Oxide Semiconductor), a VTCMOS (Variable Threshold Complementary Metal Oxide Semiconductor), power source gate control, multi-voltage and DVFS (Dynamic Voltage and Frequency Scaling), power gating d the like, thus the power consumption of a chip system is the minimum on the premise of ensuring circuit performances of the chip system.

Description

technical field [0001] The invention belongs to the field of integrated circuit design automation, in particular to the technical category of optimizing integrated circuit power consumption, in particular to a low-power consumption circuit design optimization method. Background technique [0002] The feature size of the advanced digital integrated circuit manufacturing process is continuously shrinking, from 90nm, 65nm, to 45nm, 32nm, and is expected to develop to 22nm and 15nm, or even smaller feature size. The continuous reduction of the feature size makes it possible to continuously improve the integration of the chip system, but the power consumption of the chip increases with the integration of the chip system, which restricts the ability to make full use of the reduction of the feature size to improve the integration of the chip system. Therefore, it is necessary to explore low-power optimization techniques to reduce the power consumption of the chip system. [0003] ...
