Description

Technical Field

[0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, apparatus, electronic device, and medium for detecting a communication chip. Background Art

[0002] With the continuous development of communication technologies, communication chips have been widely used in fields such as mobile communication, wireless networks, and wireless data transmission industries. The functional safety of communication chips has a great impact on all walks of life.

[0003] At present, the detection of communication chips mainly focuses on obvious quality problems such as whether the communication chip can communicate normally, whether it can camp on a cell, or whether a communication link can be established. However, there is less detection of the functional safety of communication chips. Only methods such as parity, error correcting code (ECC), redundant design, or dual lock step can be used to detect the functional safety of communication chips.

[0038] The following further elaborates on the embodiments of the present invention in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the embodiments of the present invention, rather than limiting the embodiments of the present invention. Additionally, it should be noted that for the sake of description, only parts related to the embodiments of the present invention are shown in the drawings, rather than all structures.

[0039] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the operations (or steps) as sequential processes, many of the operations can be implemented in parallel, concurrently, or simultaneously. In addition, the order of the operations can be rearranged. When the operations are completed, the process can be terminated, but there can also be additional steps not included in the drawings. The process can correspond to a method, function, procedure, sub - routine, sub - program, etc.

[0040] For ease of understanding, the main inventive concept of the embodiments of the present invention is briefly described.

[0041] In the prior art, the detection of communication chips mainly focuses on obvious quality problems such as whether the communication chip can communicate normally, whether it can camp on a cell, or whether a communication link can be established. However, the functional safety detection of communication chips is less, and only methods such as Parity, ECC, redundant design, or Dual Lock step can be used to perform functional safety detection on communication chips.

[0042] The functional safety detection methods of Parity and ECC communication chips in the prior art cannot accurately distinguish test nodes, resulting in low test coverage; the functional safety detection methods of redundant design and dual lock step communication chips improve functional safety at the expense of chip resources and performance, and these two methods can only test communication chips in an offline state.

[0043] In view of the problems of low coverage rate of the functional safety detection method for communication chips and the consumption of a large amount of communication chip resources and performance during the detection process in the prior art, the inventors considered whether it is possible to test the functional safety of communication chips during idle time slots, with the aim of increasing the detection coverage rate as much as possible without consuming a large amount of communication chip resources and performance.

[0044] The inventors analyzed the vehicle-to-everything (V2X) communication chips and their communication protocols. C-V2X is a vehicle wireless communication technology evolved from cellular network communication technologies such as the 3rd-Generation (3G), 4th-Generation (4G), or 5th-Generation (5G) mobile communication technologies. It includes two communication interfaces: one is the short-distance direct communication interface (PC5) between vehicles, people, and roads, and the other is the communication interface (Uu) between terminals and base stations, which can achieve reliable communication over long distances and a larger range. C-V2X is a communication technology based on the global unified standard of the 3rd Generation Partnership Project (3GPP), including LTE-V2X and 5G-V2X. From the perspective of technology evolution, LTE-V2X supports smooth evolution to 5G-V2X. The inventors respectively analyzed the time slot frame structures of LTE-V2X based on the PC5 and Uu interfaces, as well as the 5G-V2X protocol. The inventors found that the radio frame structures of the PC5 interface, Uu interface, and 5G-V2X all adopt the time division duplex (TDD) system. Therefore, it is feasible to detect idle time slots and perform functional safety detection on communication chips through the idle time slots.

[0045] Based on the above considerations, the inventors creatively proposed that during the operation of the communication chip, detect the idle time slots at the receiving end of the communication chip; generate test vectors online and generate corresponding standard results; construct a data frame containing the test vectors and send the data frame to the receiving end of the communication chip through the idle time slots for processing to obtain the chip processing results; perform a systematic comparison between the standard results and the chip processing results. This realizes the online detection of the functional safety of communication chips and solves the problems of low detection coverage rate of communication chips and the consumption of a large amount of communication chip resources and performance in the prior art.

[0046] Embodiment 1

[0047] Figure 1It is a flowchart of a receiving - end detection method for a communication chip in Embodiment 1 of the present invention. This embodiment is applicable to the situation of performing functional safety detection on the receiving end of a communication chip during the operation of the communication chip. This method can be executed by a receiving - end detection device of the communication chip. The device can be implemented in software and / or hardware and integrated in a computer device that executes this method. Specifically, referring to Figure 1 , the method specifically includes the following steps:

[0048] S110. During the operation of the communication chip, detect the idle time slot of the receiving end of the communication chip.

[0049] Specifically, the communication chip involved in the embodiment of the present invention can be a communication chip involved in fields such as vehicle - to - everything (V2X), mobile communication, wireless network, and wireless data transmission industry. It should be noted that the detection method of the communication chip involved in the embodiment of the present invention can test any kind of communication chip.

[0050] Specifically, the receiving end of the communication chip is mainly used to receive communication signals sent by other modules or chips. The communication chip can process the communication signals received through the receiving end of the communication chip and send the processed communication signals to the sending end of the communication chip. Through the sending end of the communication chip, the processed communication signals can be sent to other modules or chips.

[0051] It should be noted that a communication protocol refers to the rules and agreements that both entities must follow to complete communication or services. Exemplarily, if it is necessary to realize the communication between communication chip A and communication chip B, the communication between communication chip A and communication chip B can be realized only by following a pre - set communication protocol.

[0052] Specifically, in this embodiment, during the operation of the communication chip, the idle time slot of the receiving end of the communication chip is detected. Among them, the idle time slot of the receiving end of the communication chip can be a time slot when the receiving end of the communication chip does not receive communication signals from other modules or chips. In this time slot, the receiving end of the communication chip does not need to receive communication signals and send the communication signals to the communication chip for processing. Exemplarily, an analog and / or digital detection signal can be sent to the receiving end of the communication chip, and according to the processing result of the communication chip on the analog and / or digital detection signal, the idle time slot of the receiving end of the communication chip can be obtained. When an idle time slot is detected, functional safety detection of the receiving end of the communication chip can be started. It should be noted that for different communication protocols, their idle time slots are different, so it is necessary to send an analog and / or digital detection signal to the receiving end of the communication chip to detect the idle time slot of the receiving end of the communication chip.

[0053] S120. Generate test vectors online and generate standard results corresponding to the test vectors.

[0054] Specifically, after detecting the idle time slot at the receiving end of the communication chip, a test vector can be generated online, and a standard result corresponding to the test vector can be generated. The test vector can be an Rx_Golden excitation or other standard test excitations, which are not limited in the embodiments of the present invention.

[0055] It should be noted that for the receiving end of the communication chip, the test vector is a modulated signal after encoding and modulation. It should be noted that the functional safety detection of the receiving end of the communication chip cannot affect the normal working process of the communication chip. Therefore, it is necessary to ensure that the power of the test vector is not higher than the power of the working time slot. Therefore, it is necessary to adjust the power of the test vector in real time based on the power of the working time slot. Exemplarily, if the power of the test vector is 2W and the power of the working time slot is 1.5W, then the power of the test vector needs to be adjusted to be less than 1.5W at this time. The advantage of such a setting is that it will not occupy too many resources of the communication chip and will not affect the use effect of the communication chip.

[0056] Optionally, the standard result corresponding to the test vector may include: a digital front-end standard result, a symbol-level standard result, and a bit-level standard result.

[0057] S130. Construct a data frame containing the test vector, and send the data frame to the receiving end of the communication chip through the idle time slot for processing to obtain a chip processing result.

[0058] Specifically, after generating the data vector online, a data frame containing the test vector can be constructed, and the constructed data frame can be sent to the receiving end of the communication chip through the idle time slot for processing to obtain a chip processing result. Exemplarily, if the data vector generated online is data vector a, it can be constructed into a data frame A containing the test vector a, and the data frame A can be sent to the receiving end of the communication chip through the detected idle time slot of the communication chip receiving end for processing to obtain a chip processing result.

[0059] Optionally, sending the data frame to the receiving end of the communication chip through the idle time slot for processing to obtain a chip processing result may include: sending the data frame to the receiving end of the communication chip through the idle time slot, and sequentially performing digital front-end processing, symbol-level processing, and bit-level processing on the data frame through the receiving system of the communication chip; respectively obtaining the digital front-end processing result, the symbol-level processing result, and the bit-level processing result as the chip processing result.

[0060] Exemplarily, data frame A can be sent to the receiving end of the communication chip through an idle time slot, and the data frame A is successively subjected to digital front-end processing, symbol-level processing, and bit-level processing through the receiving system of the communication chip to obtain the digital front-end processing result, symbol-level processing result, and bit-level processing result for the data frame A respectively, and these processing results are used as the chip processing results.

[0061] S140. Systematically compare the standard result with the chip processing result.

[0062] Specifically, after obtaining the chip processing result, the standard result is systematically compared with the chip processing result. It can be determined whether the consistency condition is satisfied between the bit-level standard result and the bit-level processing result; if so, it is determined that the receiving end of the communication chip is secure, and the loop detection program is entered to start the next test; if not, the digital front-end standard result and the digital front-end processing result are obtained for comparison, and the symbol-level standard result and the symbol-level processing result are obtained for comparison to obtain the segmented comparison result.

[0063] Exemplarily, the bit-level standard result and the bit-level processing result can be compared first, and it is determined whether the consistency condition is satisfied between the bit-level standard result and the bit-level processing result; if the consistency condition is satisfied between the two, it can be determined that the receiving end of the communication chip is secure, and the functional safety detection of the receiving end of the communication chip in the next loop can be performed; if the consistency condition is not satisfied between the two, the detection failure point Fail point is reported to the host or server, and the digital front-end standard result and the digital front-end processing result are continuously obtained for comparison and the symbol-level standard result and the symbol-level processing result are obtained for comparison to obtain the segmented comparison result. The advantage of such a setting is that the fault range can be accurately determined or the fault range can be narrowed through the segmented comparison result, which can facilitate the user to quickly find the fault point to maintain the communication chip.

[0064] The solution of this embodiment realizes the online detection of the functional safety of the receiving end of the communication chip by detecting the idle time slot of the receiving end of the communication chip during the operation of the communication chip; online generating test vectors and generating standard results corresponding to the test vectors; constructing a data frame containing the test vectors and sending the data frame to the receiving end of the communication chip through the idle time slot for processing to obtain the chip processing result; and systematically comparing the standard result with the chip processing result. It solves the problems of low detection coverage rate of communication chips and consumption of a large amount of communication chip resources and performance during the detection process in the prior art.

[0065] Application Scenario

[0066] To better understand the embodiments of the present invention, Figure 2Enumerates a vehicle networking communication chip, which mainly includes: a main control subsystem 210, a baseband subsystem 220, a peripheral interface 230, and a radio frequency interface 240. Among them, the main control subsystem 210 mainly includes: a Random Access Memory (RAM), a timer, an internal memory, and a Direct Memory Access (DMA); the baseband subsystem 220 mainly includes: a control Digital Signal Processor (DSP), a vector DSP, a communication accelerator, and an interrupt controller; the peripheral interface 230 mainly includes: Double Data Rate (DDR3 / 4), Universal Serial Bus 3.0 (USB3.0), Industrial Ethernet (Ethemet), Universal Asynchronous Receiver / Transmitter (UART), Serial Peripheral Interface (SPI) and other interfaces; the radio frequency interface 240 mainly includes: a broadband high-speed interface, a narrowband low-speed interface, a time synchronization interface, and a radio frequency control interface. Among them, the control DSP, the vector DSP, the communication accelerator, the interrupt controller, the radio frequency interface, and the internal memory constitute the communication subsystem. It can be seen that the complexity of the vehicle networking communication chip is relatively high. Therefore, it is difficult to perform on-line testing on the vehicle networking communication chip, and it is necessary to accurately locate the fault point of the communication chip.

[0067] In a specific example of this application scenario, the receiving end of the above vehicle networking communication chip is detected. Figure 3 Is a flowchart of a method for detecting the receiving end of a vehicle networking communication chip enumerated. Specifically, the method specifically includes the following steps:

[0068] S310, Start; that is, start the on-line functional safety detection of the receiving end of the vehicle networking communication chip.

[0069] S320, Detect idle time slots; that is, send analog and / or digital detection signals to the receiving end of the vehicle networking communication chip, and obtain the idle time slots of the receiving end of the vehicle networking communication chip according to the processing results of the vehicle networking communication chip on the analog and / or digital detection signals. If an idle time slot is detected, the receiving end of the vehicle networking communication chip is detected; otherwise, the normal working process of the vehicle networking communication chip continues.

[0070] S330. Generate Rx_Golden incentives online and generate corresponding standard results for the Rx_Golden incentives. Among them, the standard results corresponding to the Rx_Golden incentives include: digital front-end standard results, symbol-level standard results, and bit-level standard results.

[0071] S340. Obtain the chip processing results. Specifically, send the data frame containing the Rx_Golden incentives to the receiving end of the vehicle networking communication chip for processing, and respectively obtain the digital front-end processing results, symbol-level processing results, and bit-level processing results.

[0072] S350. System comparison. Determine whether the consistency condition is satisfied between the bit-level standard results and the bit-level processing results. If so, determine that the receiving end of the vehicle networking communication chip is secure and start the next detection of the receiving end of the vehicle networking communication chip. If not, determine that there is a fault in the receiving end of the vehicle networking communication chip, upload the Fail point to the host, and perform segmented comparison.

[0073] S360. Segmented comparison. Compare the digital front-end standard results with the digital front-end processing results, and compare the symbol-level standard results with the symbol-level processing results to obtain the segmented comparison results. When the segmented comparison results are inconsistent, upload the Fail point to the host.

[0074] In this application scenario, during the operation of the vehicle networking communication chip, the idle time slots of the receiving end of the vehicle networking communication chip are detected; Rx_Golden incentives are generated online and corresponding standard results for the Rx_Golden incentives are generated; the data frame containing the Rx_Golden incentives is sent to the receiving end of the vehicle networking communication chip for processing to obtain the chip processing results; the chip processing results and the standard results are respectively subjected to system comparison and segmented comparison. The precise positioning of the fault points of the vehicle networking communication chip is realized, and the problems of low detection coverage rate of communication chips and consumption of a large amount of communication chip resources and performance during the detection process in the prior art are solved.

[0075] Embodiment 2

[0076] Figure 4 It is a flowchart of a method for detecting the transmitting end of a communication chip in Embodiment 2 of the present invention. This embodiment is applicable to the situation of performing functional safety detection on the transmitting end of a communication chip during the operation of the communication chip. This method can be executed by a detection device for the transmitting end of the communication chip, and this device can be implemented in a software and / or hardware manner and integrated in a computer device that executes this method. Specifically, refer to Figure 4 , and this method specifically includes the following steps:

[0077] S410. During the operation of the communication chip, detect the idle time slots of the transmitting end of the communication chip.

[0078] Specifically, during the operation of the communication chip, the number of idle time slots can be obtained from the system configuration parameters. It should be noted that the sending end of the communication chip mainly sends the processing results of the communication chip to other modules or chips according to the communication protocol. Therefore, by only querying the communication protocol of the communication chip in the system configuration parameters, the idle time slots of the sending end of the communication chip can be detected; there is no need to, like the receiving end of the communication chip, obtain the idle time slots of the receiving end of the communication chip by sending analog and / or digital detection signals to the receiving end of the communication chip and according to the processing results of the communication chip on the analog and / or digital detection signals.

[0079] S420. Generate test vectors online and generate standard results corresponding to the test vectors.

[0080] Specifically, after detecting the idle time slots of the sending end of the communication chip, test vectors can be generated online and standard results corresponding to the test vectors can be generated. Among them, the test vectors can be Tx_Golden incentives or other standard test incentives, which are not limited in the embodiments of the present invention.

[0081] Optionally, the standard results corresponding to the test vectors include: bit-level standard results, symbol-level standard results, and digital front-end standard results.

[0082] S430. Construct a data frame containing the test vectors and send the data frame to the sending end of the communication chip through the idle time slots for processing to obtain the chip processing results.

[0083] Specifically, after generating the data vectors online, a data frame containing the test vectors can be constructed and the constructed data frame can be sent to the sending end of the communication chip through the idle time slots for processing to obtain the chip processing results. Exemplarily, if the data vector generated online is data vector a, it can be constructed into a data frame A containing test vector a, and the data frame A can be sent to the sending end of the communication chip through the detected idle time slots of the communication chip sending end for processing to obtain the chip processing results.

[0084] Optionally, sending the data frame to the receiving end of the communication chip through the idle time slots for processing to obtain the chip processing results may include: sending the data frame to the sending end of the communication chip through the idle time slots, and sequentially performing bit-level processing, symbol-level processing, and digital front-end processing on the data frame through the sending system of the communication chip; respectively obtaining the bit-level processing results, symbol-level processing results, and digital front-end processing results as the chip processing results.

[0085] Exemplarily, data frame A can be sent to the transmitting end of the communication chip through an idle time slot, and the receiving system of the communication chip sequentially performs bit-level processing, symbol-level processing, and digital front-end processing on data frame A to obtain the bit-level processing result, symbol-level processing result, and digital front-end processing result for data frame A respectively, and these processing results are used as the chip processing results.

[0086] It should be noted that for the transmitting end of the communication chip, the test vector is the original bit information. Therefore, the transmitting system of the communication chip needs to perform bit-level processing on the data frame containing the test vector first, then perform symbol-level processing, and finally perform digital front-end processing.

[0087] S440. Systematically compare the standard result with the chip processing result.

[0088] Specifically, after obtaining the chip processing result, the standard result is systematically compared with the chip processing result. It can be judged whether the digital front-end standard result and the digital front-end processing result meet the consistency condition; if so, it is determined that the transmitting end of the communication chip is secure; if not, the bit-level standard result and the bit-level processing result are obtained for comparison, and the symbol-level standard result and the symbol-level processing result are obtained for comparison to obtain the segmented comparison result.

[0089] Exemplarily, the digital front-end standard result can be compared with the digital front-end processing result first, and it can be judged whether the digital front-end standard result and the digital front-end processing result meet the consistency condition; if the two meet the consistency condition, it can be determined that the receiving end of the communication chip is secure, and the functional safety detection of the transmitting end of the communication chip in the next cycle can be performed; if the two do not meet the consistency condition, the detection Fail point is reported to the host or server, and the bit-level standard result and the bit-level processing result are continuously obtained for comparison and the symbol-level standard result and the symbol-level processing result are obtained for comparison to obtain the segmented comparison result. The advantage of such a setting is that the fault range can be accurately determined or narrowed down through the segmented comparison result, which can facilitate the user to quickly find the fault point for maintaining the communication chip.

[0090] The solution of this embodiment realizes the online functional safety detection of the transmitting end of the communication chip by detecting the idle time slot of the transmitting end of the communication chip during the operation of the communication chip; generating test vectors online and generating standard results corresponding to the test vectors; constructing a data frame containing the test vectors and sending the data frame to the transmitting end of the communication chip through the idle time slot for processing to obtain the chip processing result; and systematically comparing the standard result with the chip processing result. It solves the problems of low detection coverage rate of communication chips and consumption of a large amount of communication chip resources and performance during the detection process in the prior art.

[0091] Application Scenario

[0092] To better understand the embodiments of the present invention, Figure 5 a flowchart of a method for detecting the transmitting end of a vehicle networking communication chip is listed. Specifically, the method specifically includes the following steps:

[0093] S510: Start; that is, start the online functional safety detection of the transmitting end of the vehicle networking communication chip.

[0094] S520: Detect idle time slots; that is, obtain the idle time slots of the transmitting end of the vehicle networking communication chip from the system configuration parameters. If idle time slots are detected, the detection of the transmitting end of the vehicle networking communication chip is performed; otherwise, the normal working process of the vehicle networking communication chip continues.

[0095] S530: Online generate Tx_Golden excitation and generate standard results corresponding to the Tx_Golden excitation. Among them, the standard results corresponding to the Tx_Golden excitation include: bit-level standard results, symbol-level standard results, and digital front-end standard results.

[0096] S540: Obtain the chip processing results; specifically, send the data frame containing the Tx_Golden excitation to the transmitting end of the vehicle networking communication chip for processing to obtain the bit-level processing results, symbol-level processing results, and digital front-end processing results respectively.

[0097] S550: System comparison; determine whether the digital front-end standard results and the digital front-end processing results meet the consistency condition; if so, determine that the transmitting end of the vehicle networking communication chip is secure and start the next detection of the transmitting end of the vehicle networking communication chip; if not, determine that there is a fault in the transmitting end of the vehicle networking communication chip, upload the Fail point to the host, and perform segmented comparison.

[0098] S560: Segmented comparison; compare the bit-level standard results with the bit-level processing results, and compare the symbol-level standard results with the symbol-level processing results to obtain the segmented comparison results; when the segmented comparison results are inconsistent, upload the Fail point to the host.

[0099] In this application scenario, during the operation of the vehicle networking communication chip, the idle time slots of the transmitting end of the vehicle networking communication chip are detected; Rx_Golden stimuli are generated online, and standard results corresponding to the Rx_Golden stimuli are generated; data frames containing the Rx_Golden stimuli are sent to the transmitting end of the vehicle networking communication chip for processing to obtain chip processing results; the chip processing results and the standard results are respectively compared systemically and segmentally. The precise positioning of the fault points of the vehicle networking communication chip is achieved, and the problems of low detection coverage rate of communication chips and consumption of a large amount of communication chip resources and performance during the detection process in the prior art are solved.

[0100] In another specific example of this embodiment, Figure 6 an online detection method for a vehicle networking communication chip is listed, which includes the detection of the receiving end of the vehicle networking communication chip and the detection of the transmitting end of the vehicle networking communication chip.
