[0002] In the layout design process, the area added for a specific purpose is called dummy. In order to improve the overall flatness of the chip and thus achieve the effect of improving the chip yield, dummy filling will be performed in the layout. For sensitive traces in the layout, on the one hand, dummy will increase trace parasitics, and on the other hand, dummy will cause inconsistent matching environment, both of which will result in a significant decrease in chip performance.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0022] This embodiment provides a method for quickly adding a dummy block layer in a layout, such as Figure 1 As shown, the following steps are included: S1, obtain layout data and input the layout data into the DRC tool; S2, obtaining sensitive routing layer data according to the layout data; the sensitive routing layer data includes: the number of sensitive routing layers and the type of sensitive routing layers; S3, create the same number of dummy block layers according to the number of sensitive routing layers; S4, define the name of the dummy block layer according to the type of sensitive routing layer; S5, obtaining sensitive routing data of each sensitive routing layer; S6, according to the sensitive routing data, adjusting the dummy blocklayer corresponding to the sensitive routing layer where the sensitive routing data is located.

[0023] It should be noted that the layout data is recorded in the inspection layout file in a digital format, which can describe the various components, routing and their connection relationships in the published drawing. The sensitive routing layer data can be obtained by screening the layout data. The sensitive routing layer includes the number of sensitive routing lines in the module and the sensitive routing layout. According to the sensitive routing layer, create a corresponding dummy block layer to add blockage to the sensitive routing layer. In order to improve the efficiency during design and facilitate subsequent layout modification work, the name of the dummy block layer is defined according to the type of sensitive routing. By obtaining the sensitive routing data of each sensitive routing layer one by one, the corresponding dummy block layer is modified respectively, thereby realizing the addition of chip blockage.

[0024] In this embodiment, by acquiring sensitive routing layer data from the layout, creating a corresponding dummy block layer according to the sensitive routing layer data, and acquiring the sensitive routing data therein to adjust the dummy block layer, the efficiency and accuracy of blockage addition are improved.

[0025] In some embodiments, step S6, according to the sensitive routing data, the dummy block layer corresponding to the sensitive routing layer where the sensitive routing data is located is adjusted, such as Figure 2 As shown, the following steps are included: S61, obtain the number of sensitive traces; S62, performing a first division on the dummy block layer according to the number of sensitive traces; S63, obtaining the number of segments of the sensitive routing according to the sensitive routing data; S64, performing a second division on the dummy block layer according to the number of segments of the sensitive routing lines.

[0026] It should be noted that the dummy block layer needs to cover the sensitive routing, and there may be multiple sensitive routings in the sensitive routing layer. Therefore, it is necessary to first obtain the number of sensitive routings in the sensitive routing layer and divide the dummy block layer. Each dummy block layer corresponds to a sensitive routing. In addition, the same sensitive routing may also have tortuous and irregular routing layouts. Therefore, it is necessary to obtain the number of segments of the sensitive routing according to the sensitive routing data and divide the dummy block layer. Each dummy block layer corresponds to a sensitive routing segment.

[0027] In this embodiment, by obtaining the number and segment number of sensitive routing lines, the dummy block layer is divided twice, thereby improving the accuracy of blockage addition.

[0028] In some embodiments, step S6, according to the sensitive routing data, the dummy block layer corresponding to the sensitive routing layer where the sensitive routing data is located is adjusted, such as Figure 2 As shown, the following steps are also included: S65, calculating the geometric center of each sensitive routing line according to the sensitive routing data; S66, adjust the position of the dummy block layer according to the geometric center of each sensitive trace; S67, adjust the size of the dummy block layer according to the sensitive routing data and the safety distance threshold.

[0029] It should be noted that by analyzing the sensitive routing data, the number of sensitive routing segments and the line width and connection point information of each sensitive routing segment can be obtained. Therefore, each sensitive routing segment can be regarded as a regular geometric body and the geometric center of each sensitive routing segment can be calculated. In some preferred embodiments, the position of the dummy block layer is adjusted by aligning the center of the dummy block layer with the geometric center of each sensitive routing segment. At the same time, considering the impact on the sensitive routing, the size of the dummy block layer needs to be adjusted according to the safety distance threshold. The safety distance threshold can be obtained and set through historical experimental data, and is not limited here.

[0030] In this embodiment, the geometric center of each sensitive routing line is calculated, the position of the dummy block layer is adjusted, and the size of the dummy block layer is adjusted according to the safety distance threshold, thereby improving the accuracy of blockage addition.

[0031] In some embodiments, step S67, the size of the dummy blocklayer is adjusted according to the sensitive routing data and the safety distance threshold, such as Figure 3 As shown, the following steps are included: S671, obtaining a preset safety distance threshold; S672, obtaining a position threshold of each sensitive routing line according to the sensitive routing data; S673, calculating the sum of the position threshold and the safety distance threshold of each sensitive routing segment to obtain a setting size; S674, adjust the size of the dummy block layer according to the set size.

[0032] It should be noted that the position threshold is the distance threshold of the geometric center of the sensitive routing segment to the edge of the sensitive routing segment, including the distance threshold of the geometric center to the left and right edges and the distance threshold of the geometric center to the upper and lower edges. It can represent the distribution of the entire sensitive routing segment. On this basis, the sum of the position threshold and the safety distance threshold of each sensitive routing segment is calculated to obtain the setting size of the dummy block layer, which can represent the distribution of the dummy block layer.

[0033] In this embodiment, by obtaining the position threshold of the sensitive routing, calculating the sum of the position threshold and the safety distance threshold, and obtaining the set size, the size of the dummy block layer is adjusted, thereby improving the accuracy of blockage addition.

[0034] In some embodiments, after adjusting the dummy block layer corresponding to the sensitive routing layer where the sensitive routing data is located according to the sensitive routing data in step S6, the following steps are also included: According to the layout data, obtain component position data and non-sensitive routing position data; Calculate the distance set between the sensitive routing and the component according to the sensitive routing data and the component position data; According to the sensitive routing data and the non-sensitive routing position data, a distance set between the sensitive routing and the non-sensitive routing is calculated; Verify the dummyblock layer based on the distance set between the sensitive routing and the component and the distance set between the sensitive routing and the non-sensitive routing; When the distance set between the sensitive routing and the component and the distance set between the sensitive routing and the non-sensitive routing are greater than the size of the dummyblock layer, add a dummy block layer to the sensitive routing.

[0035] It should be noted that the above method of adding a dummy block layer is based on the sensitive routing data in the layout, and does not take into account the layout of components and non-sensitive routing in the layout. Therefore, when the design is completed, the dummy block layer needs to be verified to verify whether it overlaps with the surrounding components and non-sensitive routing. When the distance between the sensitive routing and the component and the distance from the non-sensitive routing is greater than the size of the dummy block layer, the verification of the dummy block layer passes and the dummy block layer is added.

[0036] In some embodiments, calculating a distance set between a sensitive routing line and a component according to the sensitive routing line data and the component position data includes the following steps: According to the sensitive routing data, edge data of each sensitive routing section is obtained; According to the edge data of each sensitive routing line and the component position data, the shortest distance between each edge segment and the component is calculated to obtain a distance set between the sensitive routing line and the component.

[0037] In some embodiments, calculating a distance set between sensitive routing lines and non-sensitive routing lines according to sensitive routing data and non-sensitive routing position data includes the following steps: According to the sensitive routing data, edge data of each sensitive routing section is obtained; According to the edge data of each sensitive routing and the position data of the non-sensitive routing, the shortest distance between each edge and the non-sensitive routing is calculated to obtain the distance set between the sensitive routing and the non-sensitive routing.

[0038] Specifically, the distance set between sensitive routing and components is calculated by obtaining the edge data of each sensitive routing segment, calculating the distance between each edge segment of each sensitive routing segment and each component, and filtering out the shortest distance, obtaining the shortest distance between the four edges of the sensitive routing segment and the component, and forming a distance set between the sensitive routing and the component. Similarly, the distance set between sensitive routing and non-sensitive routing can be obtained. Based on the above distance set, verify whether the dummy block layer overlaps the components and non-sensitive routing around the sensitive routing segment.

[0039] In this embodiment, by acquiring component position data and non-sensitive routing position data, calculating the distance between the sensitive routing and the component and the distance between the sensitive routing and the non-sensitive routing, the dummy block layer is verified, thereby improving the accuracy of blockage addition.

[0040] This embodiment provides a system for quickly adding a dummy block layer in a layout, and applies the above-mentioned method for quickly adding a dummy block layer in a layout, such as Figure 4 include: Layout data acquisition module, sensitive routing layer data acquisition module, dummy block layer creation module, dummy block layer classification module, sensitive routing data acquisition module and dummy block layer adjustment module; A layout data acquisition module is used to acquire layout data and input the layout data into the DRC tool; A sensitive routing layer data acquisition module is used to acquire sensitive routing layer data according to layout data; the sensitive routing layer data includes: the number of sensitive routing layers and the type of sensitive routing layers; The dummy block layer creation module is used to create the same number of dummy block layers according to the number of sensitive routing layers; The dummy block layer classification module is used to define the name of the dummy block layer according to the type of sensitive routing layer; A sensitive routing data acquisition module, used to acquire sensitive routing data of each sensitive routing layer; The dummy block layer adjustment module is used to adjust the dummy block layer corresponding to the sensitive routing layer where the sensitive routing data is located according to the sensitive routing data.
