The present specification relates to the field of
chip design and manufacturing, and particularly to a
chip leakage power consumption optimization method and device based on graph partitioning. The method comprises: judging whether there is timing path margin in a
chip, wherein the chip has physical
perception capability; if yes, identifying low
threshold voltage devices in the chip according to a plurality of preset constraint conditions, and performing graph partitioning on the device
layout of the chip; based on the
processing result of the graph partitioning, determining target optimization devices from the low
threshold voltage devices that meet the preset constraint conditions; replacing the target optimization devices with high
threshold voltage devices to optimize the chip
leakage power consumption containing the target optimization devices. The present application constructs an optimized
leakage power consumption operation space based on a physically perceived
engineering environment. Through graph partitioning and replacement constraints, the combined logic devices are analyzed, replaced and optimized in a limited range, the data scale is controllable, the chip
layout is optimized in the chip design and implementation process, and the optimization efficiency is improved.
