It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. In addition, the structure shown in the accompanying drawings is often part of the actual structure. In particular, the emphasis that each drawing needs to show is different, and sometimes different proportions are used.
[0018] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present invention are used to distinguish similar objects in order to describe the embodiments of the present invention, rather than to describe a specific order or sequence. It should be understood that the structures used in this way can be interchanged under appropriate circumstances. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0019] This embodiment provides a method for locating coordinates of a layout segmentation area. Figure 1 As shown, including: S1, obtain a large piece of the map; S2, obtains all character coordinates from the large map; S3, determining the end coordinates of the divided small layout according to the measured structure in the large layout; S4, determining the segmentation coordinates of the large layout according to the end coordinates of the small layout, so as to segment the large layout using the segmentation coordinates.
[0020] The coordinate positioning method for the layout cutting area provided in this embodiment can ensure the correctness of the layout cutting area by determining the end coordinates of the small layout according to the measured structure; by determining the cutting coordinates according to the end coordinates, it can ensure that the cutting area contains the complete measured structure; the entire process does not require human participation, improves the efficiency and accuracy of layout cutting, and solves the problem of how to improve the efficiency of layout cutting.
[0021] Specifically, in this embodiment, step S1, the method of obtaining a large block of layout can be implemented by relying on layout design software and a redeveloped script.
[0022] In practical applications, calibre software can be used to obtain large layouts and perform subsequent layout segmentation operations. In addition, GDS or OAS files can be input to obtain a complete large layout.
[0023] Calibre is an electronic design automation (EDA) tool for integrated circuit design verification, mainly used to ensure that the design meets the requirements of the manufacturing process. It provides a series of key functions, including design rule checking (DRC), layout and schematic Figure 1 Features such as LVS, parasitic extraction, and optical proximity effect (OPE) together form a powerful toolset that covers every step from design to manufacturing.
[0024] Furthermore, in this embodiment, step S2, the method of obtaining all character coordinates from the large layout includes: The center position coordinates of each test point of the measured structure in the large layout are obtained, and the center position coordinates of each test point of the measured structure in the large layout are used as the character coordinates.
[0025] In practical applications, the -PreserveTextAttributes function of the calibre software can be used to identify and output the coordinates of all characters in a large block of the layout. These characters are located at the center of each test point (pad) of the measured structure (testkey); then, all the identified character coordinates are summarized to output the coordinates of each character in the large block of the layout.
[0026] calibre's -PreserveTextAttributes option is used to preserve text attributes when merging GDS or OAS files. This ensures consistency of text attributes for each measured structure in a large layout, making it easier to locate coordinates.
[0027] Further, in this embodiment, in step S3, the method of determining the end coordinates of the divided small layout according to the measured structure in the large layout includes: According to the design manual of the measured structure in the large layout, the character coordinates of the lower left test point in the measured structure are obtained to obtain the first end coordinates, and the character coordinates of the upper right test point in the measured structure are obtained to obtain the second end coordinates.
[0028] In practical applications, an end coordinate detection script can be written, and then the end coordinate detection script can be used to determine the character coordinates of the lower left test point and the upper right test point of each small layout in one click in combination with the design manual when the measured structure was published. In this way, it replaces the manual identification and segmentation of the area, which not only greatly saves labor and improves work efficiency, but also ensures that the obtained end coordinates are accurate, meeting the needs of layout segmentation based on the measured structure.
[0029] Furthermore, in this embodiment, in step S4, the method of determining the segmentation coordinates of the large layout according to the end coordinates of the small layout, and using the segmentation coordinates to segment the large layout includes: According to the preset rules, the end coordinates are converted into segmentation coordinates.
[0030] In order to ensure that the measured structure in the small block after the layout is divided is complete and meets the test requirements, it is necessary to obtain the first division coordinates (x1', y1') in the lower left and the second division coordinates (x2', y2') in the upper right required for division based on the first end coordinates (x1, y1) in the lower left and the second end coordinates (x2, y2) in the upper right.
[0031] Specifically, in this embodiment, Figure 2 As shown, for the first end coordinate (x1, y1): according to the horizontal design distance between the two test points in the measured structure, the abscissa x1 of the first end coordinate is translated to the left by the first horizontal distance; according to the vertical design distance between the test point in the measured structure and the structural line below, the ordinate y1 of the first end coordinate is translated downward by the first vertical distance; the abscissa of the first end coordinate after translation is used as the abscissa of the first split coordinate, and the ordinate of the first end coordinate after translation is used as the ordinate of the first split coordinate.
[0032] In a specific embodiment, when the measured structure is designed, the horizontal distance between the two test points is 65μm, then the horizontal coordinate x1 of the first end coordinate can be translated 35μm to the left to obtain the horizontal coordinate of the first segmentation coordinate, that is, x1'=x1-35(μm). In this way, not only can the integrity of the measured structure in the currently segmented small block be guaranteed, but also the adjacent measured structure on the left will not be damaged by the segmentation. And, when the measured structure is designed, the distance between the test point and the structure (frame) line below is 35μm, then the vertical coordinate y1 of the first end coordinate can be translated downward by 35μm to obtain the vertical coordinate of the first segmentation coordinate, that is, y1'=y1-35(μm). In this way, not only can the integrity of the measured structure in the currently segmented small block be guaranteed, but also the adjacent measured structure below can be guaranteed not to be damaged by the segmentation.
[0033] And, for the second end coordinate (x2, y2): according to the horizontal design distance between the two test points in the measured structure, the abscissa x2 of the second end coordinate is translated to the right by the second horizontal distance; according to the vertical design distance between the test point in the measured structure and the structural line below, the ordinate y2 of the second end coordinate is translated upward by the second vertical distance; the abscissa of the second end coordinate after the translation is used as the abscissa of the second split coordinate, and the ordinate of the second end coordinate after the translation is used as the ordinate of the second split coordinate.
[0034] In a specific embodiment, when the measured structure is designed, the horizontal distance between the two test points is 65 μm, then the abscissa x2 of the second end coordinate can be translated to the right by 35 μm to obtain the abscissa of the second segmentation coordinate, that is, x2'=x2+35 (μm). In this way, not only can the measured structure in the currently segmented small block be guaranteed to be complete, but also the adjacent measured structure on the right can be guaranteed not to be damaged by the segmentation.
[0035] For the ordinate of the second split coordinate, in the prior art, it is necessary to consider a variety of situations where the measured structure is located at different distances from the test point, such as the measured structure is located in the middle of the test point (0 unit distance from the center of the left and right test points), the measured structure is located one unit distance above the center of the left and right test points, the measured structure is located two unit distances above the center of the left and right test points, etc., and the ordinate of the second end coordinate is translated to different degrees according to the situation classification to obtain the ordinate of the second split coordinate, and the processing method is relatively complicated.
[0036] In order to reduce the amount of system calculation, this embodiment proposes a method for obtaining the ordinate of the second segmentation coordinate: first, the ordinate of the second end coordinate is translated upward by the third vertical distance to obtain the middle ordinate, which is marked as y3, y3>y2; then, according to the vertical design distance between the test point and the lower structure line in the measured structure, the middle ordinate is translated downward by the fourth vertical distance. For example, when the measured structure is designed, the distance between the test point and the lower structure (frame) line is 35μm, then the middle ordinate y3 can be translated downward until the distance between y3 and the lower structure line is 35μm, so as to obtain the ordinate of the first segmentation coordinate. In this way, not only can the integrity of the measured structure in the currently segmented small block be guaranteed, but it can also be applied to situations where various measured structures are at different distances from the test point. In this way, the difference between the third vertical distance and the fourth vertical distance is the second vertical distance.
[0037] Preferably, in order to ensure that the measured structure above the current small block is not destroyed by cutting, when determining the middle ordinate y3, it is necessary to find the minimum ordinate value just above the ordinate y2 of the second end coordinate. Figure 3 As shown, we can first count the ordinate y2 of the second end coordinates corresponding to all small blocks, and then traverse each ordinate: if y2 i <y2, then discard y2 i , directly compare the next vertical coordinate; if y2 i >y2, then assign y2i to y3, and for the next ordinate y2 i+1 For comparison, if y2<y2 i+1 <y2 i , that is, y2<y2 i+1 <y3, then y2 i+1 Assign to y3; if y2 i+1 >y2 i , or y2 i+1 <y2, then discard y2 i+1 , and continue to compare the next ordinate. This continues until all ordinates are traversed and the minimum value greater than y2 is found to obtain the middle ordinate y3.
[0038] In addition, considering that the area in the first row of the large layout cannot find a value of the vertical coordinate greater than the second end coordinate to serve as the vertical coordinate of the second split coordinate, therefore, in this embodiment, if the second end coordinate is located in the first row of the large layout, the vertical coordinate of the second split coordinate is manually read and set directly in the large layout.
[0039] In practical applications, the first horizontal distance may be half of the horizontal design distance between the two test points; the second horizontal distance may be half of the horizontal design distance between the two test points; and the first vertical distance may be the vertical design distance between the test point and the underlying structure line. Of course, in other embodiments, the first horizontal distance, the second horizontal distance, and the first vertical distance may be adjusted on this basis to ensure that the measured structure in the currently segmented small block is intact, and the surrounding adjacent measured structures will not be damaged by the segmentation.
[0040] Finally, the obtained segmentation coordinates are counted, and the area of the small layout is divided according to the corresponding segmentation coordinates, thereby realizing the layout segmentation.
[0041] The coordinate positioning method for the layout segmentation area provided in this embodiment relies on the script to run automatically throughout the entire process, without the need for human intervention. This not only reduces the amount of manual work and labor costs, but also can effectively improve the efficiency and accuracy of the coordinate positioning of the segmentation area. The coordinate positioning method for the layout segmentation area provided in this embodiment converts the end coordinates into segmentation coordinates according to preset rules, which can be applied to various types of measured structural situations, greatly simplifies the amount of calculation, and further improves the efficiency of the coordinate positioning of the segmentation area.
[0042] This embodiment also provides a layout segmentation region coordinate positioning device, which is used to implement the layout segmentation region coordinate positioning method as described above. Figure 4 As shown, the layout segmentation area coordinate positioning device includes: The layout acquisition module is used to obtain large blocks of layout; The character coordinate acquisition module is used to obtain all character coordinates from the large layout; The end coordinate detection module is used to determine the end coordinates of the divided small layout according to the measured structure in the large layout; The segmentation coordinate calculation module is used to determine the segmentation coordinates of the large layout according to the end coordinates of the small layout, so as to segment the large layout using the segmentation coordinates.
[0043] Furthermore, this embodiment further provides an electronic device, comprising a memory, a processor, and an executable program stored in the memory and capable of being run by the processor; when the processor runs the executable program, the layout segmentation area coordinate positioning method as described above is executed.
