Abstract

The present invention relates to the field of electronic technology, in particular to a method and device for arranging a power-off unit, which includes determining the position of each normally-conducting metal wire in the voltage range that can be turned off and the length of the power-off unit. The turn-off voltage sub-area corresponding to the normally-on metal line; for a turn-off voltage sub-area, determine the arrangement rules of the power supply shutdown unit in the turn-off voltage sub-area, so that the turn-off voltage The power shutdown units in the sub-regions are placed at intervals; the power shutdown units are placed in all the shutdown voltage regions so that the power shutdown units in the shutdown voltage regions are placed at intervals to reduce power shutdown the number of units.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and a device for arranging a power-off unit. Background technique [0002] With the reduction of process feature size and the increase of complexity, integrated circuit design is facing many challenges, such as higher and higher speed, increasing area, and more serious noise phenomenon. [0003] At present, in addition to timing and area, power consumption has become an increasingly concerned factor in integrated circuit design. The power consumption density per unit area has risen sharply, and the leakage current has increased exponentially. In advanced technology chip design, the leakage current is already as large as the dynamic current, and the static power consumption that was once negligible has become the main part of the power consumption. [0004] In the design of low power consumption, the method of power-gating is commonly used to control the static power...
