For example, fig. 2 is a schematic diagram of a differential line detection interface in the first embodiment of the present invention, where, as shown in fig. 2, the differential line detection interface includes a selection Check layer control (Select checking layer), a completion control (OK), a detection control (Check), and a cancel highlighting control (unSelect), where, in response to a triggering operation of a user on a drop-down list corresponding to the selection Check layer control in the differential line detection interface, the Check layer list is displayed, and in response to a touch operation of the user on identification information of a target Check layer in the Check layer list, the target Check layer is determined; responding to the triggering operation of a user on a detection control in the differential line route detection interface, triggering a differential line detection instruction, wherein the detection instruction can carry the identification information of a target inspection layer; responding to the trigger operation of the user for completing the control in the differential line route detection interface, and closing the differential line route detection interface; and responding to the triggering operation of canceling the highlight control in the differential line route detection interface by the user, cleaning the checked object on the PCB, canceling the highlight display effect and avoiding the error selection of the object. The differential line detection interface may further include a first threshold filling frame (max diffpair mismatch), where the first threshold is a maximum allowable length difference of each differential line pair in the same non-empty network differential pair in the same target inspection layer, a user may input the first threshold according to an actual requirement, and the differential line detection interface may further include a second threshold filling frame (manual check margin), where the second threshold is a length difference threshold of a differential line pair in the first type non-empty network differential pair, and the first type non-empty network differential pair is a non-empty network differential pair to be detected manually, and the user may input the second threshold according to an actual requirement.

In the context of the present invention, a computer-readable storage medium may be a tangible medium that can contain, or store a computer program for use by or in connection with an instruction execution system, apparatus, or device. The computer readable storage medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. Alternatively, the computer readable storage medium may be a machine readable signal medium. More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) through which a user can provide input to the electronic device. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user may be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user may be received in any form, including acoustic input, speech input, or tactile input.

The systems and techniques described here can be implemented in a computing system that includes a background component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such background, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), wide Area Networks (WANs), blockchain networks, and the internet.

The computing system may include clients and servers. The client and server are typically remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical hosts and VPS service are overcome.

It should be appreciated that various forms of the flows shown above may be used to reorder, add, or delete steps. For example, the steps described in the present invention may be performed in parallel, sequentially, or in a different order, so long as the desired results of the technical solution of the present invention are achieved, and the present invention is not limited herein.

The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives are possible, depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
