Abstract

The present application provides a power switch planning method, device, device and storage medium for a chip, which belong to the technical field of chip design. The method includes: acquiring unit planning information of a plurality of programmable power switch units in a target chip, where the unit planning information includes: position information of the programmable power switch units; and obtaining layout information of sample power switch units according to the unit planning information, wherein the sample The power switch unit is any one of a plurality of programmable power switch units; according to the layout information of the sample power switch units and the position information of each to-be-planned power switch unit, the layout information of each to-be-planned power switch unit is determined, wherein the to-be-planned power switch unit is determined. The power switch unit is a power switch unit other than the sample power switch unit among the multiple programmable power switch units. The present application can improve the efficiency of planning.

Description

technical field [0001] The present application relates to the technical field of chip design, and in particular, to a method, apparatus, device, and storage medium for planning a power switch of a chip. Background technique [0002] In the design process of the chip, in order to reduce the power consumption of the chip, it is usually necessary to divide the chip into multiple areas. When a certain area of ​​the chip is not working, the power supply to the chip in this area can be reduced or the chip in this area can be directly operated. power down, thereby reducing power consumption. [0003] In the prior art, in the design of the area division of the chip, the technical means used is usually to judge each area in the chip one by one, so as to determine whether the area is a controllable area of ​​a power switch (Power Switch) unit. [0004] However, this method consumes a lot of time in the planning process. For designs that require a large number of power switch units to...
