Abstract

The invention provides a method and system for obtaining a compressible area in a layout file and electronic equipment, and the method comprises the steps: opening a layout file which comprises a plurality of device areas, wherein each device area comprises a doped area connected to a power supply or the ground; scanning the layout file to select a blank area between two adjacent doped areas; judging whether the blank area is rectangular or not: if the blank area is rectangular, determining that the blank area is a compressible area. According to the invention, the compressible area in the layout file can be obtained.

Description

technical field [0001] The invention relates to the technical field of integrated circuit design, in particular to a method, system and electronic equipment for obtaining a compressible area in a layout file. Background technique [0002] In layout design, many devices share power or ground, especially devices placed in parallel can save layout area by sharing power or ground. However, when layout engineers design layouts, they can only rely on design experience to design manually, and there may be the possibility of not sharing power or ground; The placed devices do not share power or ground, and there may be layout space that can be saved in the layout file. Therefore, in order to know the amount of layout space that can be saved in the layout file, a method for obtaining the compressible area in the layout file is needed. Contents of the invention [0003] The object of the present invention is to provide a method, system and electronic device for obtaining a compress...
