In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves.
Fig. 2 is a schematic flow chart of a method for determining coplanar waveguide transmission line paths in a rectangular confinement frame according to an embodiment of the present invention, and referring to fig. 2, the method for determining coplanar waveguide transmission line paths in a rectangular confinement frame according to an embodiment of the present invention includes steps S100 to S400, where:
s100, determining the distribution positions of signal input points and signal output points at the boundary of the rectangular constraint frame.
Illustratively, as shown in fig. 4 to 6, the signal output point is a and the signal input point is B. In one embodiment, the distribution positions of the signal output point a and the signal input point B at the boundary of the rectangular bounding box are one of the following three conditions:

the signal input point B and the signal output point a are located at the same boundary of the rectangular bounding box, as shown in fig. 6.
It should be noted that, in this step, the area in the rectangular bounding box refers to a part of the area that is reserved and left empty during chip design, the area is rectangular and is used for designing and constructing the coplanar waveguide transmission line, and the boundary of the reserved or left empty area is the "boundary of the rectangular bounding box".

Specifically, the rectangular bounding box has 4 boundaries, denoted as l respectively1、l2、l3、l4The signal input point B and the signal output point a are respectively located at any one of the 4 boundaries and are perpendicular to the boundary, and the signal input direction points to the inside of the rectangular constraint box and the signal output direction points to the outside of the rectangular constraint box. Specifically, as shown in conjunction with FIGS. 4-6, there is a rectangular bounding box, l, in the XOY coordinate system1、l3Parallel to the Y axis,/2、l4Parallel to the X-axis, wherein the signal input point B is at l1The signal output point A is at3When, as shown in FIG. 4, the signal input direction is equal to1Vertical, signal output direction and3vertically; as shown in FIG. 5, signal input point B is at l4The signal output point A is at3The signal input direction is equal to4Vertical, signal output direction and3vertically; as shown in FIG. 6, signal input point B is at l4The signal output point A is at4The signal input direction is equal to4Vertical, signal output direction and4and is vertical.
S300, determining a main propagation direction from the signal input direction to the signal output direction. In this embodiment, the main propagation direction is used as a reference in the determining process of the coplanar waveguide transmission line path, and is used for determining the extending direction of the components of the coplanar waveguide transmission line path, and calculating intermediate parameters, such as the number of the components.
Preferably, when this step is implemented specifically, the implementation manners corresponding to the distribution positions of the signal output point a and the signal input point B at the boundary of the rectangular constraint frame respectively are as follows:
referring to fig. 4, when the signal input point B and the signal output point a are located at two opposite boundaries of the rectangular bounding box, for example, the signal input point B is at l1The signal output point A is at3Determining a direction being simultaneously parallel to said signal input direction and said signal output direction as a main propagation direction, i.e. parallel to the X-axis and X + to X-arrow in fig. 4;

referring to fig. 6, when the signal input point B and the signal output point a are located at the same boundary of the rectangular bounding box, for example, the signal input point B is at l4The signal output point A is at4The direction perpendicular to both the signal input direction and the signal output direction is determined as the main propagation direction, as shown by the arrow from X + to X-axis parallel to the X-axis in fig. 6.
S400, determining a smoothly arranged coplanar waveguide transmission line path from the signal input point B to the signal output point A, wherein: and the included angle between the coplanar waveguide signal transmission direction of any point on the coplanar waveguide transmission line path and the main propagation direction is less than or equal to 90 degrees.
This step determines the coplanar waveguide transmission line path based on the distribution positions of the signal input point B, the signal output point a at the boundary of the rectangular bounding box, the signal input direction and the signal output direction, and the main propagation direction determined in the preceding step. In order to present a precise image of the determined coplanar waveguide transmission line path, in one embodiment, the determined coplanar waveguide transmission line path includes a pattern layer of the center conductor and a pattern layer of the center conductor to ground gap, such as in fig. 4-6, "//" fill area is the pattern layer of the center conductor and "+" is the pattern layer of the center conductor to ground gap.
At present, the area occupation of the coplanar waveguide transmission line is usually reduced by appropriate bending, but even then, the influence of the bending shape on the signal transmission needs to be considered, and if the bending is excessive, the bending can be significantly deviated from the design parameters, such as signal reflection, resonance frequency shift, and the like. Therefore, in this embodiment, it is ensured that the coplanar waveguide transmission line path is a smooth curve, and a tangent line at each point on the coplanar waveguide transmission line path, that is, a transmission direction of a signal at the point when the coplanar waveguide transmission line is operated, is characterized.
In an embodiment, as shown in fig. 3, the determining a smoothly arranged coplanar waveguide transmission line path from the signal input point B to the signal output point a specifically includes:
s401, determining components for forming the transmission line path of the coplanar waveguide; illustratively, in conjunction with fig. 7, in one embodiment, the component elements comprise a circular arc element and a straight line element, the circular arc element and the straight line element being tangent when connected. In one embodiment, each of the arc element and the straight line element includes a layer of the central conductor and a layer of the central conductor to ground gap, and the layer width of the central conductor to ground gap are predetermined according to signal transmission requirements, relevant parameters of the substrate, and the like. The arc value of the arc element can be any preset arc value, and the radius of the arc element can be any preset value, wherein in a more preferred embodiment, the straight line element comprises a first straight line element perpendicular to the reference direction and a second straight line element parallel to the reference direction, the arc element comprises a half arc element and a quarter arc element, and the half arc element and the quarter arc element have the same preset radius parameter R. It should be noted that the preset radius parameter R represents a radius parameter corresponding to a center line of the circular arc element, for example, a radius parameter of a central dashed line at each circular arc in fig. 4 to 6.
In order to reduce crosstalk occurring during signal transmission, in this embodiment, the preset radius parameter R is set to be greater than 3 times the width of the central conductor of the coplanar waveguide transmission line, that is, the radius of the arc element, for example, the radius of the quarter arc element and the radius of the half arc element are both greater than 3 times the width of the central conductor, for example, when the preset radius R is 10 times the width of the central conductor, crosstalk occurring between positions during signal transmission can be effectively avoided.
S402, determining the coplanar waveguide transmission line path by using the component elements based on the main propagation direction, the signal input direction and the signal output direction. Namely, a straight line element and a circular arc element, such as a quarter circular arc element and a half circular arc element are used for generating a coplanar waveguide transmission line path from B to A, and the included angle between the signal transmission direction of the coplanar waveguide and the main propagation direction is ensured to be less than or equal to 90 degrees at any point of the generated coplanar waveguide transmission line path.
It should be noted that the number of circular arc elements, for example, the number of half circular arc elements and quarter circular arc elements, the number of straight line elements, and the size of each straight line element, can be determined by calculation according to the preset length L of the transmission line path of the coplanar waveguide, and the position parameters from the signal input point B to the signal output point a, for example, coordinate values in the XOY coordinate system.
In another embodiment, the determining the smoothly arranged coplanar waveguide transmission line path from the signal input point B to the signal output point a is implemented after the steps S401 to S402, and further includes step S403:
s403, determining the length of the coplanar waveguide transmission line path, and judging whether the length of the coplanar waveguide transmission line path reaches a preset threshold value.
When the step is implemented, one of the implementation manners is an implementation manner of determining the length of the coplanar waveguide transmission line path by using segmented calculation, that is, determining the length of the coplanar waveguide transmission line path, and determining whether the length of the coplanar waveguide transmission line path reaches a preset threshold L, and specifically includes:
s4031, determining the total length of an arc on the coplanar waveguide transmission line path according to the preset radius parameter R;
s4032, determining the total length of straight lines on the transmission line path of the coplanar waveguide according to the straight line elements;
s4033, determining the length of the coplanar waveguide transmission line path based on the total arc length and the total straight line length.
