Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of chip tunnel bridge arrangement, and more particularly to a method and apparatus for automated arrangement of superconducting quantum chip tunnel bridges. Background Art

[0002] In existing technology, the layout of tunnel bridges along linear components is mostly a manual process performed by designers. The typical design process involves manually selecting key locations within the linear component, adding tunnel bridges one by one based on experience, and adjusting their positions and angles to meet process requirements. However, this approach has drawbacks. First, manual tunnel bridge placement is time-consuming and inefficient. Modern superconducting quantum chip designs typically involve large-scale, complex linear components, and manually placing tunnel bridges at each critical location consumes significant time and human resources. Second, ensuring consistent tunnel bridge placement quality is difficult. Manual placement is easily influenced by the designer's experience and judgment, resulting in uneven spacing between tunnel bridges, misalignment with linear components, and even intersections or collisions, which can affect chip performance. Third, there is a lack of optimization support for complex paths and turns. For designs with multi-segment linear paths or rounded turns, existing tools do not provide an effective automated solution. Designers must additionally calculate the rotation angles and precise positions of the tunnel bridges, further increasing design complexity. Summary of the Invention

[0017] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0018] Figure 1 This is a process 100 of some embodiments of the method for automatically arranging a superconducting quantum chip tunnel bridge according to some embodiments of the present disclosure. The method for automatically arranging a superconducting quantum chip tunnel bridge comprises the following steps: Step 101: Determine geometric information of control lines in a superconducting quantum chip.

[0019] In some embodiments, an entity (e.g., a computing device) executing the automated layout method for a superconducting quantum chip tunnel bridge can determine geometric information about control lines in the superconducting quantum chip. This geometric information includes a set of path points, line width, and corner radius.

[0020] Control line position description structure dictionary. This data structure is used to describe the path point set of the control line and path characteristics (such as width, corner radius, etc.). It specifically includes the following fields: Field Name Data Type illustrate POS List A set of points on the control line path, recording the geometric position of the control line. width Float Controls the width of the line. corner_radius Float Controls the fillet radius of line corners. line_type String Controls the type of line (e.g. circular, straight, etc.). chip_type String The identifier of the chip type. Tunnel bridge description structure dictionary. This data structure is used to record the relevant information of the generated tunnel bridge, including its location, direction angle, and whether it intersects with other tunnel bridges. Field Name Data Type illustrate path List A collection of tunnel and bridge spawn points. rotation Float The rotation angle of the tunnel bridge is usually perpendicular to the tangent direction of the path. outline List The outer contour point set of the tunnel bridge is used to detect whether it intersects with other structures. chip String The identifier of the chip type. As an example, the path point set pos, line width width and corner radius corner_radius. The system automatically generates a FlexPath object based on the input control line data. Its corresponding path is a polyline described by the point set pos, with a width of width, and automatically rounded corners by setting the corner_radius parameter. The initial control line shape is as follows Figure 2 Indicated by yellow lines.

[0021] Step 102: For each corner path in the control line where a tunnel bridge needs to be added, perform the following processing steps: Step 1021 , determining the minimum point coordinates, the center point coordinates, and the maximum point coordinates corresponding to the corner path.

[0022] In some embodiments, the execution entity can determine the minimum, center, and maximum coordinates corresponding to the corner path. First, a tunnel bridge is added at the corner of the control line. To achieve better coverage, the tunnel bridge is also generated using a FlexPath object. Therefore, tunnel bridge generation also requires a path point set pos, a line width width, and a corner radius corner_radius. The corner radius is consistent with the control line, and the line width is 1.5 times the control line width. Finally, the path point set path for the tunnel bridge is generated.

[0023] As an example, in control line generation, it is known that only three points are needed to generate a FlexPath with a corner. Here, the point with the smallest horizontal coordinate (minimum point coordinate) among the three points is start (X0, Y0), the center point (center point coordinate) is end (X1, Y1), and the point with the largest horizontal coordinate (maximum point coordinate) is next (X3, Y3).

[0024] It should be noted that the plane where the control line is located has a pre-set coordinate system, and the minimum point coordinates, the center point coordinates and the maximum point coordinates can be obtained by pre-measurement.

[0025] Step 1022 : Determine the left line segment coordinates and the right line segment coordinates corresponding to the corner path according to the minimum point coordinates, the center point coordinates, and the maximum point coordinates.

[0026] In some embodiments, the execution entity may determine the left line segment coordinates and the right line segment coordinates corresponding to the corner path according to the minimum point coordinates, the center point coordinates, and the maximum point coordinates.

[0027] As an example, the point should fall on the straight line segments on both sides and should be close to the center point end. The distance is defined as 120 (which can be optimized later according to the line length and is required to be slightly longer than the corner radius). The line segments on both sides are divided equally by this distance (rounded up if it is not long enough). Assuming that it is divided into t equal parts, the coordinate calculation formula of the point selected on the line segment on the left side of the corner (the coordinates of the left line segment) (X4, Y4) is: X4=(1-t)*X1+t*X0 Y4=(1-t)*Y1+t*Y0.

[0028] The coordinate calculation formula of the point selected on the right side of the corner (right side segment coordinates) (X5, Y5) is: X5=(1-t)*X1+t*X3 Y5=(1-t)*Y1+t*Y3.

[0029] Therefore, we can construct the set of path points path: (X4, Y4), (X1, Y1), (X5, Y5).

[0030] Step 1023 : Determine the slopes of the starting side line segment and the ending side line segment corresponding to the corner path according to the left side line segment coordinates and the right side line segment coordinates.

[0031] In some embodiments, the execution entity may determine the slopes of the starting side line segment and the ending side line segment corresponding to the corner path according to the left side line segment coordinates and the right side line segment coordinates.

[0032] In practice, the execution entity may determine the slopes of the starting side segment and the ending side segment corresponding to the corner path through the following steps: The first step is to draw a perpendicular line to the control line through the coordinates of the left line segment as the first perpendicular line.

[0033] The second step is to draw a perpendicular line to the control line through the coordinates of the right line segment as the second perpendicular line.

[0034] In the third step, the intersection point of the first perpendicular line and the inner side of the arc of the corner path is taken as the first inner line intersection point.

[0035] In the fourth step, the intersection point of the first perpendicular line and the outer side of the arc of the corner path is taken as the first outer line intersection point.

[0036] Step 5: The intersection point of the second perpendicular line and the inner side of the arc of the corner path is the second inner line intersection point.

[0037] Step 6: The intersection point of the second perpendicular line and the outer side of the arc of the corner path is the second outer line intersection point.

[0038] In the seventh step, the slopes of the starting side line segment and the ending side line segment corresponding to the corner path are determined based on the coordinates corresponding to the first inner line intersection point, the first outer line intersection point, the second inner line intersection point and the second outer line intersection point.

[0039] As an example, we make perpendicular lines of the control line (the first perpendicular line and the second perpendicular line) through these two points (the coordinates of the left segment and the right segment), and we can get four intersection points. We define the perpendicular line through (X4, Y4) as line1, and the perpendicular line through (X5, Y5) as line2. We define the intersection point of line1 and the inner side of the control line corner arc as line1_in, the intersection point of line1 and the outer side of the control line corner arc as line1_out, the intersection point of line2 and the inner side of the control line corner arc as line2_in, and the intersection point of line2 and the outer side of the control line corner arc as line2_out. We define the coordinates of the two intersection points of line1 and line2 as a pair of coordinate pairs. From this pair of coordinates, we can get the slope calculation formula of the starting side segment and the ending side segment as: K=(Y line1_out -Y line1_in ) / (X line1_out -X line1_in ).

[0040] Among them, the coordinates of line1_out are (X line1_out , Y line1_out );The coordinates of line1_in are (X line1_in , Y line1_in ).

[0041] Step 1024: Determine the extension point information corresponding to the corner path according to the slope and the line width.

[0042] In some embodiments, the execution entity may determine extension point information corresponding to the corner path based on the slope and the line width. The extension point information includes: coordinates of an extension point outside the starting lateral center, coordinates of an extension point inside the starting lateral center, coordinates of an extension point inside the ending lateral center, and coordinates of an extension point outside the ending lateral center. The center of the circle may be the common center of the inner and outer arcs of the corner path.

[0043] As an example, the coordinates of the starting lateral circle center outer extension point are point 6, the starting lateral circle center inner extension point are point 7, the ending lateral circle center inner extension point are point 8, and the ending lateral circle center outer extension point are point 9. Width is the width of the tunnel bridge (1.5 times the width of the control line). The calculation formula is: .

[0044] Among them, the coordinates of the starting lateral extension point outside the center of the circle are (X6, Y6), the coordinates of the starting lateral extension point inside the center of the circle are (X7, Y7), the coordinates of the ending lateral extension point inside the center of the circle are (X8, Y8), and the coordinates of the ending lateral extension point outside the center of the circle are (X9, Y9).

[0045] Step 1025: Draw a tunnel bridge on the corner path based on the geometric information and the extension point information.

[0046] In some embodiments, the execution entity may draw a tunnel bridge on the corner path based on the geometric information and the extension point information. Figure 3 In the example shown, through the above path point set path and the coordinates of each extension point (point 6, point 7, point 8, point 9), the bridge body of the tunnel bridge of each corner path can be drawn through the gdspy library.

[0047] In practice, the execution entity can draw a tunnel bridge on the corner path by following the steps below: The first step is to determine the tunnel bridge width corresponding to the corner path based on the geometric information. For example, the tunnel bridge width can be determined as 1.5 times the width of the control line.

[0048] In the second step, based on the corner radius and the tunnel bridge width included in the above geometric information, the starting side line segment and the ending side line segment of the tunnel bridge body corresponding to the above corner path are determined through the above extension point information, and the tunnel bridge body is drawn.

[0049] For example, the line between line1_in and line1_out can be determined as the starting side segment. The line between line2_in and line2_out can be determined as the ending side segment. The tunnel bridge body is drawn based on the corner radius included in the above geometric information and the above tunnel bridge width.

[0050] The third step is to draw a bridge triangle between the corner path and the bridge body based on the intersection information and the extension point information to complete the tunnel bridge. The intersection information includes: the first inner line intersection point, the first outer line intersection point, the second inner line intersection point, and the second outer line intersection point.

[0051] Based on the four extension points (point 6, point 7, point 8, point 9) calculated above and the intersection points of the four perpendicular lines (point line1_in, point line1_out, point line2_in, point line2_out), I got four sets of point pairs. Each set of point pairs is one point short of drawing a triangle. We can use the position of the triangle and the rotation angle of the bridge body, with the intersection as the center, to rotate the connecting line 90 degrees to obtain the coordinates of the third point of each set of point pairs, and then connect the lines in sequence to obtain four sets of triangles. Below, take the first tunnel bridge as an example. The line segment with a slope of 0 is rotated 90° clockwise to the line segment with an infinite slope. The rotation angle is defined as -90° (positive if counterclockwise). At this time, the perpendicular line formed by line1_in, line2_out and its corresponding extension points needs to be rotated 90° counterclockwise with the foot of the perpendicular as the vertex to obtain the third vertex, and the perpendicular line formed by line1_out, line2_in and its corresponding extension points needs to be rotated 90° clockwise with the foot of the perpendicular as the vertex to obtain the third vertex. The arc segment drawing effect is as follows: Figure 4 shown.

[0052] Optionally, for each straight path in the control line to which a tunnel bridge is to be added, perform the following processing steps: The first step is to select the starting side segment and the ending side segment from top to bottom on the above straight path, and define the outer point and the inner point in order from left to right, and calculate the extension point coordinates of the outer point and the inner point, and draw the tunnel bridge body corresponding to the above straight path according to the extension point coordinates.

[0053] The second step is to draw a bridge triangle between the straight path and the main body of the tunnel bridge based on the outer and inner points corresponding to the straight path and the coordinates of each extension point to completely draw the tunnel bridge.

[0054] As an example, let's add a tunnel bridge to a straight line segment. Tunnels and bridges added to a straight line segment should not overlap with those in an arc segment. Therefore, we need to use the points (X4, Y4) and (X5, Y5) generated previously, give a custom straight line segment tunnel bridge length and number, calculate whether the specified number and length of tunnel bridges can be arranged within the remaining length of the line segment (if the line segment length is exceeded, the maximum number is used), and return a set of path points for the bridges that can be arranged at equal intervals. The following example illustrates this: For example, given (X4, Y4) is (0, 0), (X5, Y5) is (100, 0), and it is required to arrange 5 tunnel bridges with a length of 42.5. The calculation shows that a maximum of two can be arranged, and the distance between the bridge bodies and the distance between the bridge bodies and the two ends are both 5. The paths of the two bridge bodies are returned, which are ((5, 0), (47.5, 0)) and ((52.5, 0), (95, 0)), and then the drawing of the complete bridge body is completed.

[0055] Optionally, all tunnel bridge information constructed through the above steps is encapsulated into a unified data structure and exported as a GDSII format file together with the path data of the control line for use in the subsequent chip manufacturing process. As an example, the final completed corner tunnel bridge and straight tunnel bridge drawing is as follows: Figure 5 The example given.
