Abstract

A method for extracting pixel devices from a layout comprises the following steps: 1) defining a pixel standard file; 2) checking that pixel standard file and the standard pixel device; 3) calculatingan effective area of the layout and an effective area of a standard pixel device; 4) performing mesh segmentation of the effective area of the layout; 5) traversing that grid, extracting the pixel device and storing the pixel device in a CSV file; 6) saving that CSV file to the designated position. Accord to the pixel array standard file defined by the user, the invention quickly extracts the pixel device in the layout and generates the pixel array file, thereby facilitating the designer to view the layout structure and improving the work efficiency of the designer to build the integrated circuit.

Description

technical field [0001] The invention relates to the field of layout design in flat panel display (Flat Panel Display) tools, and is especially suitable for the layout design of special-shaped panels. Background technique [0002] In the layout design, the designer hopes to obtain the CSV file of the pixel device corresponding to the layout. After obtaining the CSV file of the pixel device, the circuit can be quickly built, and the device structure of the layout can also be viewed. [0003] However, with the sudden emergence of special-shaped panel designs and more and more irregular-shaped layouts, manual extraction is no longer advisable, and the speed cannot meet the requirements of rapid development. Therefore, fast and accurate extraction of pixel array is the function that customers hope to achieve. Contents of the invention [0004] In order to solve the deficiencies in the prior art, the object of the present invention is to provide a method for extracting pixel de...
