Chip Placement Method of Analog Custom Demand Integrated Circuits

摘要

The present invention relates to a chip arrangement method of an analog custom-demand integrated circuit. In forming an analog integrated circuit into chips arranged in cells, the aspect ratio of the unit signal processing module is 1: 1, 1: 2, and 2: 1, the basic standard size is selected to occupy a certain area, and the horizontal and vertical shape of the cell is an integer multiple of the basic standard size, the horizontal aspect ratio is an integer ratio and the horizontal, vertical and Unit signal processing module during designing for chipping of all integrated circuits by standardizing into a cross-sectional pattern having a width of the width of each unit signal, which is an integer multiple of the basic standard size. All you need to do is list and combine the cells normalized to a specific shape without changing the pattern of, and re-lay out only the metal masks that connect them As may shorten the actual time, there is an effect that can enhance the Sigil of God even in the actual mask pattern.
