Description

Technical Field

[0001] This application relates to the field of data processing, and more particularly to a method, system, chip, electronic device, storage medium, and computer program product for determining wiring channels. Background Technology

[0002] As the nanometer-scale manufacturing process of integrated circuits approaches its physical limits, many-core processors are evolving towards heterogeneous integration. This involves flexibly modularizing and integrating discrete chips of different sizes, functions, and types—such as central processing units (CPUs), graphics processing units (GPUs), and application-specific integrated circuits (ASICs)—through two-dimensional and three-dimensional methods. Horizontally, high-density interconnects are achieved between chips using redistribution layers (RDLs), while vertically, signal transmission is achieved through technologies like through-silicon vias (TSVs). However, with the continuous increase in computing power, the number of interfaces between chips is also increasing, leading to higher wiring density in the interface links and thus increased crosstalk between signals, severely impacting signal quality. According to TSMC's calculations, if the vertical interconnect spacing of chip stacks is reduced from the current 36 micrometers to 0.9 micrometers, the interconnect density can increase by at least three orders of magnitude, achieving a transmission rate more than tenfold. Therefore, signal link crosstalk suppression in heterogeneous integration has become a key technology for improving computing power.

[0003] Many-core processors use a 3D architecture to interconnect multiple chips, such as... Figure 1 As shown, in the vertical direction, multiple chip units are connected and transmit signals via TSVs and microbumps. In the horizontal direction, interconnections between chip units are achieved through interposers, and interconnections between multiple chip units in the system can also be achieved through a printed circuit board (PCB). However, in the interconnection between chip units, the interface traces are basically fixed, the wiring density often depends on the number of interfaces, and there are often signal transmission timing deviations caused by the interface positions. This not only degrades the transmitted signal but also increases design and wiring costs.

[0004] The cabling density of traditional heterogeneous interconnects depends on the number of interconnect interfaces. The more interfaces there are, the higher the cabling density within a limited area, leading to a significant increase in crosstalk between cablings and thus degrading the quality of transmitted signals. Currently, there is an urgent need for a method to determine the optimal interface-to-cabling path connection that minimizes crosstalk. Summary of the Invention

[0005] This application provides a wiring channel determination method, system, chip, electronic device, storage medium, and computer program product.

[0006] This application provides a wiring channel determination method for a system, which includes a first chip unit, a second chip unit, and a processing unit. The first chip unit and the second chip unit are electrically connected through multiple wiring channels. One end of each wiring channel is electrically connected to a corresponding output interface on the first chip unit, and the other end is electrically connected to a corresponding input interface on the second chip unit. The method includes:

[0007] The crosstalk parameters of each wiring channel are determined sequentially based on the output signals sent from each output interface of the first chip unit to the second chip unit and the actual input signals after the output signals pass through the wiring channels corresponding to the output interfaces. The crosstalk parameters characterize the degree of crosstalk influence on the wiring channel. The connection relationship between each output interface and the multiple wiring channels is determined based on the crosstalk parameters of each wiring channel and the performance requirements of the output interface corresponding to each wiring channel.

[0008] The step of determining the crosstalk parameters of each wiring channel based on the output signals sent from each output interface of the first chip unit to the second chip unit and the actual input signals after the output signals pass through the wiring channels corresponding to the output interfaces includes: The multiple wiring channels are traversed.

If not, the wiring channel corresponding to the current output interface is switched to another wiring channel until the crosstalk parameter of the switched wiring channel meets the target condition indicated by the performance requirement parameter of the output interface. After the traversal is completed, the connection relationship between each output interface and the multiple wiring channels is obtained.

[0011] The step of determining whether the cabling channel meets the target conditions indicated by the performance requirement parameters of the output interface based on the crosstalk parameters of the cabling channel corresponding to the current output interface includes: If the crosstalk parameter is less than or equal to the crosstalk requirement parameter indicated by the performance requirement parameter, the cabling channel is determined to meet the target condition.

[0012] The step of determining whether the cabling channel meets the target conditions indicated by the performance requirement parameters of the output interface based on the crosstalk parameters of the cabling channel corresponding to the current output interface includes: Receive multiple test signals sent by the current output interface and the actual output test signal after the test signals pass through the wiring channel; The expected output test signal is determined based on the loss parameters of the wiring channel and the corresponding test signal; Determine the target number of instances where the expected output test signal of the wiring channel does not match the corresponding actual output test signal. If the target quantity is less than the preset quantity, the wiring channel is determined to meet the target condition.

[0013] Another embodiment of this application provides a wiring channel determination system, the system including a first chip unit, a second chip unit, and a processing unit; the first chip unit and the second chip unit are electrically connected through multiple wiring channels; one end of each wiring channel is electrically connected to a corresponding output interface on the first chip unit, and the other end is electrically connected to a corresponding input interface on the second chip unit; the processing unit is electrically connected to both the first chip unit and the second chip unit. The processing unit sequentially determines the crosstalk parameters of each wiring channel based on the output signals sent from each output interface of the first chip unit to the second chip unit and the actual input signals after the output signals pass through the wiring channels corresponding to the output interfaces. The crosstalk parameters characterize the degree of crosstalk influence on the wiring channel. The processing unit also determines the connection relationship between each output interface and the plurality of wiring channels based on the crosstalk parameters of each wiring channel and the performance requirement parameters of the output interfaces corresponding to each wiring channel.

[0014] The processing unit traverses the plurality of wiring channels; receives the output signal of the output interface corresponding to the current wiring channel; receives the actual input signal after the output signal passes through the current wiring channel; determines the crosstalk parameters of the wiring channel based on the output signal and the actual input signal; and obtains the crosstalk parameters of each wiring channel after the traversal is completed.

[0015] The processing unit determines the expected input signal based on the loss parameters of the wiring channel and the output signal; and determines the signal difference of the wiring channel based on the expected input signal and the actual input signal, and determines the signal difference as the crosstalk parameter of the wiring channel.

[0022] In the above scheme, the processing unit receives the output signals sent by each output interface of the first chip unit, as well as the actual input signals of the output signals reaching the second chip unit after passing through the corresponding wiring channels. Combining these two signals, a crosstalk parameter characterizing the degree of crosstalk influence of each wiring channel is determined. Then, based on the crosstalk parameters of each wiring channel and the performance requirement parameters of each output interface, matching rules are established, and the connection relationship between each output interface and multiple wiring channels is determined. This ensures that output interfaces with higher crosstalk resistance requirements are matched with wiring channels with lower crosstalk influence. Simultaneously, for cases where performance requirement parameters or crosstalk parameters are consistent, matching is completed according to the corresponding rules. This accurately identifies the degree of crosstalk influence on each wiring channel, thereby achieving optimal connection matching between output interfaces and wiring channels, rationally planning the connection relationship between interfaces and wiring channels in heterogeneous interconnects, effectively reducing crosstalk influence between wirings, improving signal transmission quality, solving the problem of increased crosstalk due to increased interface numbers and wiring density in heterogeneous interconnects, and improving the overall signal transmission stability of heterogeneous interconnects.

Detailed Implementation

[0026] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] To determine the interface and wiring channel connection relationship that minimizes crosstalk, one embodiment of this application provides a wiring channel determination method applied to a system. The system includes a first chip unit, a second chip unit, and a processing unit. The first chip unit and the second chip unit are electrically connected through multiple wiring channels. One end of each wiring channel is electrically connected to a corresponding output interface on the first chip unit, and the other end is electrically connected to a corresponding input interface on the second chip unit. Figure 2 As shown, the method includes: Step 101: Determine the crosstalk parameters of each wiring channel in sequence based on the output signals sent from each output interface of the first chip unit to the second chip unit and the actual input signals after the output signals pass through the wiring channels corresponding to the output interfaces. The crosstalk parameters characterize the degree of crosstalk influence on the wiring channel.

[0028] The processing unit is electrically connected to the first chip unit. When the first chip unit outputs output signals through each output interface, it will synchronously output output signals to the processing unit, and the processing unit will receive the output signals output by the first chip unit.

[0029] The processing unit is electrically connected to the second chip unit. The second chip unit receives the actual input signal after the output signal passes through the wiring channel, and then synchronously transmits the actual input signal to the processing unit. The processing unit receives the actual input signal transmitted by the second chip unit. The actual input signal is the signal obtained after the output signal has suffered signal loss due to line loss, surrounding electromagnetic interference, etc., during transmission through the wiring channel.

[0030] The processing unit can calculate the signal difference between the output signal and the corresponding actual input signal, and use this signal difference as a crosstalk parameter to characterize the degree of crosstalk influence on the wiring channel. The larger the signal difference, the greater the degree of crosstalk influence on the wiring channel.

[0031] For example, if the output signal amplitude sent by the first chip unit output interface A is 10V, and the actual input signal amplitude at the second chip unit input interface A after transmission through wiring channel A is 7V, the signal difference between the two is 3V, then the crosstalk parameter of wiring channel A is 3V. If the output signal amplitude sent by output interface B is 10V, and the actual input signal amplitude at input interface B after transmission through wiring channel B is 5V, the signal difference between the two is 5V, then the crosstalk parameter of wiring channel B is 5V. If the output signal amplitude sent by output interface C is 10V, and the actual input signal amplitude at input interface C after transmission through wiring channel C is 8V, the signal difference between the two is 2V, then the crosstalk parameter of wiring channel C is 2V.

[0032] The processing unit can also calculate the signal attenuation rate between the output signal and the corresponding actual input signal, and use this signal attenuation rate as a crosstalk parameter to characterize the degree of crosstalk influence on the wiring channel. The signal attenuation rate is the ratio of the difference between the output signal and the actual input signal to the output signal, that is, the difference divided by the output signal. The larger the signal attenuation rate, the greater the degree of crosstalk influence on the wiring channel.

[0033] For example, if the output signal amplitude sent by the first chip unit output interface A is 20V, and the actual input signal amplitude at the second chip unit input interface A after transmission through wiring channel A is 16V, and the calculated signal attenuation rate is 20%, then the crosstalk parameter of wiring channel A is 20%. If the output signal amplitude sent by output interface B is 20V, and the actual input signal amplitude at the input interface B after transmission through wiring channel B is 12V, and the calculated signal attenuation rate is 40%, then the crosstalk parameter of wiring channel B is 40%. If the output signal amplitude sent by output interface C is 20V, and the actual input signal amplitude at the input interface C after transmission through wiring channel C is 18V, and the calculated signal attenuation rate is 10%, then the crosstalk parameter of wiring channel C is 10%.

[0034] Step 102: Determine the connection relationship between each output interface and the multiple wiring channels based on the crosstalk parameters of each wiring channel and the performance requirement parameters of the output interface corresponding to each wiring channel.

[0035] In this embodiment, the processing unit stores preset performance requirement parameters for each output interface. These parameters include at least the crosstalk immunity requirement information for the signal transmission corresponding to the output interface. A higher crosstalk immunity requirement indicates a higher sensitivity of the output interface's signal transmission to crosstalk, necessitating a matching cabling channel with lower crosstalk impact. Simultaneously, the processing unit sorts the crosstalk parameters of each cabling channel. A smaller crosstalk parameter indicates a lower degree of crosstalk impact on the cabling channel. The processing unit then establishes matching rules between the output interface performance requirement parameters and the cabling channel crosstalk parameters, matching the output interface with the highest crosstalk immunity requirement to the cabling channel with the lowest crosstalk parameter, the second highest crosstalk immunity requirement to the second lowest crosstalk parameter, and so on, determining a one-to-one correspondence between all output interfaces and multiple cabling channels. If some output interfaces have identical performance requirement parameters, they are randomly matched according to the magnitude of the cabling channel crosstalk parameter or sequentially matched according to the output interface and cabling channel number order. If the crosstalk parameters of the wiring channels are consistent, they are matched sequentially according to the performance requirements of the output interfaces. Ultimately, the optimal connection relationship between the output interface and the wiring channel is determined based on the performance requirements and crosstalk parameters. This ensures that the output interface, which is sensitive to signal transmission, is matched with the wiring channel with the lowest crosstalk impact, thereby reducing the overall crosstalk impact after the interconnection interface and the wiring channel are connected.

[0036] In the above scheme, the processing unit receives the output signals sent by each output interface of the first chip unit, as well as the actual input signals of the output signals reaching the second chip unit after passing through the corresponding wiring channels. Combining these two signals, a crosstalk parameter characterizing the degree of crosstalk influence of each wiring channel is determined. Then, based on the crosstalk parameters of each wiring channel and the performance requirement parameters of each output interface, matching rules are established, and the connection relationship between each output interface and multiple wiring channels is determined. This ensures that output interfaces with higher crosstalk resistance requirements are matched with wiring channels with lower crosstalk influence. Simultaneously, for cases where performance requirement parameters or crosstalk parameters are consistent, matching is completed according to the corresponding rules. This accurately identifies the degree of crosstalk influence on each wiring channel, thereby achieving optimal connection matching between output interfaces and wiring channels, rationally planning the connection relationship between interfaces and wiring channels in heterogeneous interconnects, effectively reducing crosstalk influence between wirings, improving signal transmission quality, solving the problem of increased crosstalk due to increased interface numbers and wiring density in heterogeneous interconnects, and improving the overall signal transmission stability of heterogeneous interconnects.

[0037] This application also provides a method for determining wiring channels in one example, such as Figure 3 As shown, the step of determining the crosstalk parameters of each wiring channel based on the output signals sent from each output interface of the first chip unit to the second chip unit and the actual input signals after the output signals pass through the wiring channels corresponding to the output interfaces includes: Step 201: Traverse the multiple wiring channels.

[0038] For example, the system has three routing channels: A, B, and C. Routing channel A connects to the output interface A of the first chip unit at one end and to the input interface A of the second chip unit at the other end. Routing channel B connects to the output interface B of the first chip unit at one end and to the input interface B of the second chip unit at the other end. Routing channel C connects to the output interface C of the first chip unit at one end and to the input interface C of the second chip unit at the other end. These three routing channels are then traversed.

[0039] Step 202: Receive the output signal of the output interface corresponding to the current wiring channel.

[0040] Step 203: Receive the actual input signal after the output signal passes through the current wiring channel.

[0041] Step 204: Determine the crosstalk parameters of the wiring channel based on the output signal and the actual input signal.

[0042] Step 205: After the traversal is completed, the crosstalk parameters of each wiring channel are obtained.

[0043] Continuing with the previous example, the processing unit first iterates to routing channel A, receiving the output signal A sent by output interface A, with an amplitude of 10V. Simultaneously, it receives the actual input signal A transmitted through routing channel A, with an amplitude of 7V. Based on the difference between the output signal A and the actual input signal A, a difference of 3V is determined, thus the crosstalk parameter of routing channel A is set to 3V. Next, it iterates to routing channel B, receiving the output signal B sent by output interface B, with an amplitude of 10V. Simultaneously, it receives the actual input signal B transmitted through routing channel B, with an amplitude of 5V. Based on the difference between the output signal B and the actual input signal B, a difference of 5V is determined, thus the crosstalk parameter of routing channel B is set to 5V. Finally, it iterates to routing channel C, receiving the output signal C sent by output interface C, with an amplitude of 10V. Simultaneously, it receives the actual input signal C transmitted through routing channel C, with an amplitude of 8V. Based on the difference between the output signal C and the actual input signal C, a difference of 2V is determined, thus the crosstalk parameter of routing channel C is set to 2V. After the traversal is complete, the crosstalk parameters corresponding to each wiring channel are obtained.

[0044] In the above scheme, multiple cabling channels are traversed sequentially. During the traversal, the output signal, actual input signal, and crosstalk parameters are received for each cabling channel one by one. After all cabling channels have been traversed, the crosstalk parameters corresponding to each cabling channel are obtained. This ensures the accurate identification of crosstalk parameters for each cabling channel, guaranteeing the integrity and accuracy of the crosstalk parameters. It provides accurate and comprehensive parameters for subsequently determining the connection relationship between the interface and the cabling channel based on the crosstalk parameters.

[0045] This application also provides a method for determining wiring channels in one example, such as Figure 4 As shown, determining the crosstalk parameters of the wiring channel based on the output signal and the actual input signal includes: Step 301: Determine the expected input signal based on the loss parameters of the wiring channel and the output signal.

[0046] For example, the system has three routing channels: A, B, and C. Routing channel A connects to the output interface A of the first chip unit at one end and to the input interface A of the second chip unit at the other end. Routing channel B connects to the output interface B of the first chip unit at one end and to the input interface B of the second chip unit at the other end. Routing channel C connects to the output interface C of the first chip unit at one end and to the input interface C of the second chip unit at the other end. The system iterates through these three routing channels. The processing unit first iterates to routing channel A and obtains the pre-stored loss parameter of routing channel A as 10%. It receives the output signal A corresponding to routing channel A, with an amplitude of 10V. It determines that the expected input signal corresponding to routing channel A is 9V. Then, it iterates to routing channel B and obtains the pre-stored loss parameter of routing channel B as 20%. It receives the output signal B corresponding to routing channel B, with an amplitude of 10V. It determines that the expected input signal corresponding to routing channel B is 8V. Finally, it iterates to routing channel C and obtains the pre-stored loss parameter of routing channel C as 30%. Receive the output signal C corresponding to wiring channel C, the amplitude of output signal C is 10V. Determine the expected input signal corresponding to wiring channel C is 7V.

[0047] Step 302: Determine the signal difference of the wiring channel based on the expected input signal and the actual input signal, and determine the signal difference as the crosstalk parameter of the wiring channel.

[0048] Continuing with the example above, during the traversal process, the processing unit receives actual input signal A with an amplitude of 7V for routing channel A, actual input signal B with an amplitude of 5V for routing channel B, and actual input signal C with an amplitude of 8V for routing channel C. Therefore, the crosstalk parameter A for routing channel A is determined to be 2V. The crosstalk parameter B for routing channel B is determined to be 3V. The crosstalk parameter C for routing channel C is determined to be 1V.

[0049] In the above scheme, the expected input signal is determined by combining the loss parameters of the cabling channel and the output signal. Then, the crosstalk parameter is determined based on the signal difference between the expected input signal and the actual input signal. This isolates the inherent loss factors of the cabling channel from the overall signal transmission deviation, avoiding the miscalculation of inherent line losses into the crosstalk effect. This makes the calculation of the crosstalk parameter more closely reflect the actual crosstalk impact on the cabling channel, more accurately characterizing the crosstalk level of each cabling channel, and significantly improving the accuracy and reliability of the crosstalk parameter.

[0050] This application also provides a method for determining wiring channels in one example, such as Figure 5As shown, determining the connection relationship between each output interface and the multiple wiring channels based on the crosstalk parameters of each wiring channel and the performance requirement parameters of the output interface corresponding to each wiring channel includes: Step 401: Traverse the multiple output interfaces.

[0051] For example, the system has three routing channels: A, B, and C. Routing channel A connects to the output interface A of the first chip unit at one end and to the input interface A of the second chip unit at the other end. Routing channel B connects to the output interface B of the first chip unit at one end and to the input interface B of the second chip unit at the other end. Routing channel C connects to the output interface C of the first chip unit at one end and to the input interface C of the second chip unit at the other end. The system iterates through output interfaces A, B, and C.

[0052] Step 402: Determine whether the cabling channel meets the target conditions indicated by the performance requirement parameters of the output interface based on the crosstalk parameters of the cabling channel corresponding to the current output interface.

[0053] Step 403: If the condition is not met, switch the wiring channel corresponding to the current output interface to another wiring channel until the crosstalk parameter of the switched wiring channel meets the target condition indicated by the performance requirement parameter of the output interface.

[0054] Step 404: After the traversal is completed, the connection relationship between each output interface and the multiple wiring channels is obtained.

[0055] For example, the processing unit first iterates to output interface A and obtains its performance requirement parameter A. Performance requirement parameter A indicates that the crosstalk parameter of the wiring channel must be less than or equal to 2V. Simultaneously, it obtains that the crosstalk parameter A of the original wiring channel A corresponding to output interface A is 3V. It determines that the crosstalk parameter A of wiring channel A does not meet the target condition indicated by performance requirement parameter A. Therefore, it controls the wiring channel corresponding to output interface A to switch from A to wiring channel B. The crosstalk parameter of wiring channel B is 1V, satisfying the target condition of crosstalk parameter less than or equal to 2V. Next, it iterates to output interface B and obtains its performance requirement parameter B. Performance requirement parameter B indicates that the target condition of the wiring channel crosstalk parameter must be less than or equal to 3V. Since wiring channel B has already been matched with output interface A, it switches the wiring channel of output interface B to wiring channel A. The crosstalk parameter of wiring channel A is 3V, satisfying the target condition of crosstalk parameter less than or equal to 3V. Finally, the process iterates to output interface C, obtaining its performance requirement parameter C. This parameter indicates the target condition is a crosstalk parameter less than or equal to 4V. The crosstalk parameter of the original wiring channel C corresponding to output interface C is found to be 3V, confirming that wiring channel C meets the target condition, and no wiring channel switching is required. After completing the traversal of output interfaces A, B, and C, the processing unit ultimately obtains the connection relationships between each output interface and multiple wiring channels: output interface A is connected to wiring channel B, output interface B is connected to wiring channel A, and output interface C is connected to wiring channel C.

[0056] In the above scheme, multiple output interfaces are traversed sequentially. During the traversal, it is determined whether the crosstalk parameters of the corresponding wiring channel for each output interface meet the target conditions indicated by its performance requirements. If not, other wiring channels are switched until the target conditions are met. After all output interfaces have been traversed, the final connection relationship is determined. By verifying and adjusting the wiring channel matching of each output interface one by one, it is ensured that each output interface can be matched with a wiring channel that meets its own performance requirements, avoiding mismatches between interfaces and wiring channels. This makes the connection relationship between output interfaces and wiring channels more closely match the actual transmission needs of each interface, effectively reducing the crosstalk impact on signal transmission of each interface, optimizing the connection matching effect between chip unit interconnection interfaces and wiring channels, and improving the overall signal transmission quality.

[0057] In one example of this application, a method for determining a cabling channel is also provided. The step of determining whether the cabling channel meets the target conditions indicated by the performance requirement parameters of the output interface based on the crosstalk parameters of the cabling channel corresponding to the current output interface includes: If the crosstalk parameter is less than or equal to the crosstalk requirement parameter indicated by the performance requirement parameter, the cabling channel is determined to meet the target condition.

[0058] If the crosstalk parameter of a cabling channel is less than or equal to the crosstalk requirement parameter indicated by the performance requirement parameter of the corresponding output interface, then the cabling channel is determined to meet the target condition. Conversely, if the crosstalk parameter of a cabling channel is greater than the crosstalk requirement parameter indicated by the performance requirement parameter of the corresponding output interface, then the cabling channel is determined to not meet the target condition.

[0059] In the above solution, the crosstalk parameters of the cabling channel are compared with the crosstalk requirement parameters indicated by the output interface performance requirements. This ensures the consistency and accuracy of whether the cabling channel meets the corresponding output interface performance requirements, providing a reliable basis for timely switching of mismatched cabling channels and making the matching and adjustment process between the output interface and the cabling channel more efficient.

[0060] This application also provides a method for determining wiring channels in one example, such as Figure 6 As shown, determining whether the cabling channel meets the target conditions indicated by the performance requirement parameters of the output interface based on the crosstalk parameters of the cabling channel corresponding to the current output interface includes: Step 501: Receive multiple test signals sent by the current output interface and the actual output test signal after the test signals pass through the wiring channel.

[0061] For example, when traversing to output interface A, the processing unit receives 10 test signals continuously sent from output interface A to input interface A, each with an amplitude of 10V. Simultaneously, the processing unit also receives 10 actual output test signals from these 10 test signals, which are transmitted sequentially through wiring channel A and then reach the second chip unit via input interface A. The amplitudes of these 10 actual output test signals are, in sequence, 9V, 8V, 9V, 8V, 9V, 10V, 9V, 7V, 9V, and 6V.

[0062] Step 502: Determine the expected output test signal based on the loss parameters of the wiring channel and the corresponding test signal.

[0063] Continuing with the above example, the processing unit obtains the pre-stored loss parameter of the cabling channel A as 10%, and calculates the expected output test signal under ideal conditions after each test signal is transmitted through the cabling channel A based on the 10% loss parameter and the 10 test signals with an amplitude of 10V sent by the output interface A, and obtains that the amplitude of each of the 10 expected output test signals is 9V.

[0064] Step 503: Determine the target number of instances where the expected output test signal and the corresponding actual output test signal of the wiring channel are inconsistent.

[0065] Continuing with the example above, the 10 expected output test signals corresponding to cabling channel A are compared one by one with the 10 actual output test signals. It is determined that the actual output test signals with amplitudes of 6V, 7V, 8V, and 10V are inconsistent with the expected output test signal amplitude of 9V, corresponding to the 2nd, 4th, 6th, 8th, and 10th signals respectively. Therefore, the target number of inconsistent expected output test signals and corresponding actual output test signals for cabling channel A is determined to be 5.

[0066] Step 504: If the target quantity is less than the preset quantity, determine that the wiring channel meets the target condition.

[0067] Continuing with the example above, the preset quantity is 6, and the target quantity of cabling channel A, 5, is less than the preset quantity of 6. Therefore, based on the judgment result, cabling channel A meets the target conditions indicated by the performance requirement parameters of output interface A.

[0068] In the above scheme, multiple test signals sent from the output interface and the actual output test signal after passing through the corresponding cabling channel are received. The expected output test signal is determined by combining the loss parameters of the cabling channel and the test signals. Then, the number of targets where the expected output test signal and the actual output test signal are inconsistent is counted. Next, it is determined whether the cabling channel meets the target conditions by judging whether the target number is less than a preset number. The matching verification of the cabling channel is completed by comparing multiple sets of test signals, which can comprehensively reflect the actual crosstalk impact of the cabling channel, making the judgment more consistent with the real transmission state of the cabling channel, avoiding the judgment deviation caused by single signal testing, and ensuring the reliability of the judgment results. This provides an accurate judgment basis for the subsequent connection matching of the interface and the cabling channel.
