Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0045] The first embodiment of the present invention relates to a coordinate data comparison method of a DRC file, which is applied in the process of developing a DRC file, see figure 1 , take the following steps:

[0046] Step S1, designing a group of layouts with design rule errors, checking the layouts using the first version of the DRC file, and saving the wrong coordinate data of the wrong graphics in the checked layout into the first database.

[0047] Step S2, check the layout using the second version of the DRC file, and save the wrong coordinate data of the wrong graphics in the checked layout to the second database.

[0048] Step S3, setting the error coordinate data comparison rules, and comparing the error coordinate data in the first database with the error coordinate data in the s...

Abstract

The invention discloses a method for contrasting coordinate data of DRC files. The method for contrasting the coordinate data of the DRC files comprises the following steps of designing a group of domains having design rule errors, using first-version DRC files to check the domains and saving wrong coordinate data of wrong graphs in the checked domains to a first database; using second-version DRC files to check the domains, and saving wrong coordinate data of wrong graphs in the checked domains to a second database; setting wrong coordinate data comparison rules, comparing the wrong coordinate data in the first database with the wrong coordinate data in the second database according to the wrong coordinate data comparison rules to obtain a comparison result. By adopting the method, the development efficiency and the accuracy of the DRC files can be ensured, and meanwhile the uniformity of the DRC files of different tools and the inheritance of different versions of DRC files are ensured.

Description

technical field [0001] The present invention relates to the field of semiconductor technology, in particular to the development of DRC (Design Rule Check, design rule check) files, in particular to a method for comparing coordinate data of different versions of DRC files. Background technique [0002] DRC files are indispensable files in semiconductor design and production. When developing different tools or different versions of DRC files, the comparison between the two has always been done manually, and there are thousands of coordinate data, and it is basically impossible to compare them point by point. , in the end there is no guarantee of unity between different tools and inheritance between different versions at all. [0003] Chinese patent (publication number: CN102129483A) discloses a method for automatically generating test vectors of layout verification rule files, which is an optimization method in layout verification (DRC) in integrated circuit aided design softw...
