Description

Method, device, medium and equipment for moving middle line segment of wiring in circuit layout Technical Field The present invention relates to the field of circuit layout design, and in particular, to a method, an apparatus, a medium, and a device for moving an intermediate line segment of a trace in a circuit layout. Background In circuit layout design, after drawing layout patterns of circuit entities such as components and pads, wiring is required to be arranged among connection points of each layout pattern so as to represent circuit connection relation. Existing wiring methods include manual wiring and automatic wiring. The manual wiring is performed manually by a designer, and the automatic wiring is performed automatically by software according to wiring rules set in advance. However, whichever way of routing is adopted, the resulting trace is difficult to fully meet the requirements of signal integrity, power distribution, timing requirements, area limitations, etc., requiring a designer to make local adjustments to the trace. In some scenarios, when moving intermediate line segments on a trace routed using polyline, it is sometimes undesirable to have the positions of other line segments on the trace change, because the positions of other line segments may already be in optimal positions, once moved, will disrupt the overall layout of the circuit layout. However, the existing layout design software does not support the moving mode, only supports the integral movement of all the line segments of the wiring, and therefore the requirements cannot be met. Disclosure of Invention The invention aims to provide a method, a device, a medium and equipment for moving an intermediate line segment of a wiring in a circuit layout, which are used for solving the problem that the wiring can only be moved integrally in the prior art, and keeping other line segments relatively unchanged when the intermediate line segment of the wiring is moved. In order to solve the technical problems, the invention provides a method for moving an intermediate line segment of a wiring in a circuit layout, which comprises the following steps: acquiring a target line segment positioned in the middle on a target line adopting broken line wiring in a circuit layout and a guide point outside the target line segment; determining a moving direction and a moving distance on the target line segment normal according to the position of the index point; translating the target line segment in the moving direction by the moving distance to obtain a mirror line segment; Searching a first intersection point of a straight line where the mirror line segment is located and a straight line where a previous line segment of the target line segment is located and a second intersection point of the straight line where a next line segment of the target line segment is located respectively; And respectively replacing the first intersection point and the second intersection point with the first end point of the previous line segment and the second end point of the subsequent line segment which are connected with the target line segment, and carrying out connection adjustment on the target wiring. Preferably, the step of performing the wire connection adjustment on the target wire includes: the straight line is connected with the first intersection point and the second intersection point; Extending the previous line segment to the first intersection point when the first intersection point is not located on the previous line segment, otherwise deleting the part from the first intersection point to the first endpoint on the previous line segment; and when the second intersection point is not positioned on the subsequent line segment, extending the subsequent line segment to the second intersection point, otherwise deleting the part from the second intersection point to the second endpoint on the subsequent line segment. Preferably, the step of determining the moving direction on the target line segment normal according to the position of the pointing point includes: constructing a first vector, in which a first end point of the target line segment connected with a previous line segment points to a second end point connected with a next line segment, a second vector, in which the first end point points to the pointing point, and a reference vector formed by clockwise rotating the first vector by a preset angle, wherein the preset angle is smaller than 180 degrees; Calculating a first vector product of the reference vector and the first vector and a second vector product of the second vector and the first vector, and comparing the directions of the first vector product and the second vector product; And when the directions are the same, taking the normal direction perpendicular to the target line segment and pointing to the right side of the first vector as a moving direction, and when the directions are different, taking the normal direction perpendicular to t
