[0002] In the production process of electronic products, the working parameters of the products need to be adjusted and the product indexes need to be measured constantly to obtain the best product quality. In the debugging process, workers operate according to the guidance of the debugging process file. The debugging items of electronic products are often more, and the efficiency of manual debugging is low, and it is easy to operate incorrectly, miss measurement and wrong measurement. In order to improve the production efficiency in the debugging process, an automatic test system needs to be developed to replace manual test. The construction of the test radio frequency link is an important part of the automatic test system.

[0003] The radio frequency routing refers to a matrix link composed of radio frequency cables or switches. At present, the radio frequency routing is constructed manually according to the test demand. The combination, optimal path and other information of the radio frequency routing are all designed manually. The construction process requires that the designer is very familiar with the product test, and also has a certain understanding of various instruments and meters. It is difficult for general automatic test system software developers to complete the design independently, and the cooperation of product debugging technical personnel is required. Therefore, the design of the radio frequency routing part is time-consuming and labor-consuming, the labor cost is high, and the unreasonable routing design causes the waste of instrument resources and the increase of cost due to the selection of too many repeated matrix switches. Especially in the enterprises with the characteristics of small batch and multiple varieties, the design of the automatic test routing increases the difficulty of popularizing and popularizing the automatic test system.

[0037] The embodiments of the present application will be described below through specific concrete examples, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the present specification. The present application can also be implemented or applied through other different specific embodiments, and each detail in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0038] Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] The design of the radio frequency routing part is time-consuming and labor-intensive, and the labor cost is high. Unreasonable routing design causes waste of instrument resources, and too many repeated matrix switches are selected in the selection of switch routes, which increases the cost. Especially in small-batch and multi-variety batch production enterprises, the design of automatic test routing increases the difficulty of popularizing and popularizing automatic test systems.

[0040] In order to solve the above technical problems, the following embodiments of the radio frequency routing automatic generation method are provided.

[0041] Embodiment 1

[0042] Referring to Figure 1 As Figure 1 shown is a flowchart of the radio frequency routing automatic generation method provided in the embodiment, which specifically includes the following steps:

[0043] Step 1: Enter all single-item routes, including instrument ends, paths, and switch channels.

[0044] Referring to Figure 2 As Figure 2 shown is a single-item route diagram of the embodiment.

[0045] Specifically, analyze the test routes required for each test item, and a complete path should include instrument ends, switch channels, and product ends. For example, to test the signal-to-noise ratio of a product, a complete route should be a test instrument (input) - product - radio frequency line (path) - test instrument (signal analysis).

[0046] Divide the instrument ends into two categories: excitation signal input and signal measurement analysis; and divide the switch channels into different categories such as switch matrix and power divider.

[0047] Enter each complete test path according to the connection relationship of all test items.

[0048] Step 2: Enter the number of products to be tested that are connected at the same time.

[0049] Specifically, enter the number of products to be tested that are connected at the same time according to test requirements.

[0050] Step 3: Enter the constraint conditions defined by the debugging process.

[0051] Specifically, analyze the instruments used in the debugging process and the debugging process flow, extract special requirements, and enter the conditions.

[0052] According to the entered conditions, select different switch matrices or tooling to form a route path that meets the requirements.

[0053] As an implementation mode, take the signal arrival timing defined by the debugging process as an example for description, referring to Figure 3 As Figure 3 shown is a signal arrival timing constraint diagram of the embodiment.

[0054] According to the debugging process, the signal output by the signal source needs to be sent to the CH1 channel of the oscilloscope and the excitation signal input port of the product at the same time to complete the excitation input and signal monitoring. The timing requirement of the signal in this embodiment is the constraint condition defined by the debugging process.

[0055] In addition to the above examples, the following also belongs to the case that needs to enter the constraint condition defined by the debugging process.

[0056] As an embodiment, two signals need to be merged and then sent to the signal analysis instrument as a new signal. In this embodiment, the two signals need to be merged, that is, the constraint condition defined by the debugging process, and the signal merging path must exist in the entire route.

[0057] As an embodiment, the output signal needs to be processed by the simulator and then sent back to the measured object as input. At this time, the signal sent back to the measured object is the constraint condition defined by the debugging process, and the path of the signal sent back to the measured object must exist in the entire route.

[0058] As an embodiment, when the path needs to use an additional special component alone, such as a low-pass filter, a high-pass filter, a mixer, etc. At this time, the use of the special component is the constraint condition defined by the debugging process, and the corresponding special component must exist in the entire route.

[0059] Step four: develop a representation method for multiple routes, which includes decomposing the multiple routes to obtain multiple paths, and regarding the multiple paths that cannot be separated alone as a constraint condition with high execution priority.

[0060] The following illustrates multiple routes:

[0061] For example, a certain signal needs to reach instrument 1 for synthesis, and then the synthesized signal is input and transmitted to the final test instrument 2 through the route to obtain the test index.

[0062] For the above multiple routes, first, the multiple routes are decomposed, and the path before signal synthesis is separately proposed as a path.

[0063] The re-input signal (i.e., the output of instrument 1) and the final test instrument 2 are regarded as another path.

[0064] It should be noted that since the above two paths cannot be separated alone, they are regarded as a special constraint condition, which is regarded as a high execution priority. In the subsequent route generation process, the above two paths are preferentially retained.

[0065] Step five: generate the route and calculate the performance of the newly generated route. After the single route entry is completed, the constraint condition is set, and the generation mode is determined, the automatic generation is started.

[0066] The performance of the route includes the number of switches, the maximum level and the maximum insertion loss. The embodiment calculates the maximum insertion loss to ensure that the generated route meets the requirement that the loss of the radio frequency signal in the transmission process is within an acceptable range, thereby avoiding inaccurate signals. The number of switches and the maximum level are calculated to ensure that the automatic test system is not too complex. If the performance of the route does not meet the requirement, the generation can be stopped.

[0067] The steps of the maximum level calculation method of the embodiment are as follows:

[0068] According to the route network, the maximum level is calculated by analyzing the single route definition level by level.

[0069] The steps of the maximum insertion loss calculation method of the embodiment are as follows:

[0070] The radio frequency matrix is connected to the vector analyzer, and the maximum insertion loss is calculated by switching to the maximum level.

[0071] The method provided in the embodiment can automatically generate a complete test radio frequency route according to a single route, the number of connected products, specific constraint conditions and the like, can comprehensively cover all test channels, can maximize the use of test instruments, and can reasonably use power dividers, matrix switches and the like.

[0072] Embodiment 2

[0073] The incremental generation method is provided in the embodiment, and the method specifically includes the following steps:

[0074] Referring to Figure 4 As shown in Figure 4 , the incremental generation schematic diagram of the embodiment is shown, and the method specifically includes the following steps:

[0075] According to each single route, the single route is added item by item. In the adding process, if a switch channel is not fully occupied, the switch channel is not additionally increased, and if the switch channel is fully occupied, a new switch channel is added. In addition, there are some special functional components, and the processing mode is the same as that of the switch channel. The special functional components include a power divider, a combiner, a filter, an attenuator, a mixer and the like.

[0076] In the adding process, the constraint condition of the multiple routes is preferentially retained, and the independence thereof is ensured as much as possible, and the constraint condition is not shared with too many resources of a low priority channel.

[0077] Finally, the single route and the multiple routes are synthesized into a route test network.

[0078] Embodiment 3

[0079] The tailoring generation method is improved in the embodiment, and the method specifically includes the following steps:

[0080] Referring to Figure 5 , as shown in Figure 5The embodiment is shown as a cutting type generation schematic diagram, and the method specifically comprises the following steps:

[0081] The single route and the special route are directly combined into a route test network, all radio frequency signal channels are listed, and the redundant part is cut according to the need.

[0082] Among them, according to the test item sequence, the combinable routes are synthesized into one.

[0083] As an implementation mode, according to the preceding uncombinable route, the subsequent channel can be combined by using a combination component, and the redundant part in the route network can also be cut.

[0084] The above only describes the preferred embodiment of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
