AI Technical Summary

Technical Problem

The existing layout graphics matching technology has a large amount of calculation and low matching efficiency. Especially when the complexity of integrated circuit design increases, it is difficult to effectively handle very large data sets and complex layout designs.

Method used

By obtaining the matching template and layout, a verification template and at least one filter template are established based on the matching template. The filter template includes graphic information for matching some graphics in the template, and the verification template includes graphic information for matching all graphics in the template. Use the filter template to filter the graphics in the layout, filter out the graphics that match the filter template, and verify these graphics through the verification template to finally obtain the final matching result.

Benefits of technology

Through multiple screening, the number of polygons and potential matching windows that need to be paid attention to during the matching process is significantly reduced, the efficiency and quality of layout graphics matching are improved, and the problems of large amount of calculation and low matching efficiency are solved.

Abstract

The invention relates to a layout matching method and device, computer equipment and a readable storage medium. The method comprises the steps of obtaining a matching template and a layout; establishing a verification template and at least one filtering template based on the matching template; the filtering template comprises graphic information of a part of graphs in the matching template; the verification template comprises graph information of all graphs in the matching template; based on the filtering template, filtering graphs in the layout, and screening to obtain a first graph matched with the filtering template; on the basis of the verification template, the first graph is verified and screened to obtain a graph matched with the verification template, the graph serves as a final matching result, and the problems that the layout matching calculation amount is large, and the matching efficiency is low are solved.
