Description

Technical Field

[0001] This invention belongs to the field of chip verification technology, specifically relating to a UVM-based TST circuit switching module verification device, system, and method. Background Technology

[0002] With the continuous development of aerospace, integrated circuits, and communication technologies, circuit switching systems, as a type of on-board switching technology, can handle satellite communication scenarios with requirements for high capacity, high reliability, and high performance. As the core of the switching system, the switching chip is crucial for thorough verification. Traditional circuit switching module verification methods mainly rely on register-transfer-level simulation and the construction of specific test platforms. However, these methods have significant drawbacks: 1. Poor reusability: The verification environment is strongly coupled with the design, making it difficult to adapt to design changes and reuse across multiple projects; 2. Insufficient scalability: For multi-channel, high-concurrency Time-Space-Time (TST) switching structures, traditional methods struggle to efficiently handle complex scenarios such as timing synchronization and resource contention; 3. Low verification efficiency: The lack of systematic approach to stimulus generation, coverage analysis, and result feedback leads to long verification cycles and high vulnerability risks.

[0003] Due to its large scale, the TST circuit switching module places higher demands on verification. Traditional methods struggle to handle challenges such as concurrent data transmission across multiple channels, the distribution of multiple switching configurations, and the constant switching of switching relationships, which can easily lead to insufficient verification or the omission of critical defects.

[0004] Among existing verification technologies, verification schemes based on the Universal Verification Methodology (UVM) have been widely used in digital circuit verification, but their systematic application in TST circuit switching modules remains a gap. However, existing technologies have not yet formed a UVM verification system specifically for TST structures, particularly lacking effective solutions in areas such as multi-channel stimulus generation, configuration information distribution and switching verification, real-time data comparison, and functional coverage analysis. Summary of the Invention

[0005] This invention provides a UVM-based verification device, system, and method for TST circuit switching modules, which can solve the problems of poor reusability, insufficient scalability, and low verification efficiency caused by the inability of existing devices to verify TST modules based on the UVM method.

[0006] In a first aspect, embodiments of the present invention provide a UVM-based TST circuit switching module verification device, comprising:

[0007] The TST data proxy component generates exchange data and inputs the exchange data to the TST switching circuit module under test, enabling multiple switching units in the TST switching circuit module under test to exchange data. The TST data proxy component also monitors the transmission process of the exchange data to obtain the exchange result of the data under test.

[0008] Multiple configuration information control agent components, each corresponding to one of the switching units, are used to generate configuration information for their respective switching units and monitor the transmission results of the configuration information.

[0009] A data switching scoring board component is used to simulate the logic implementation of the switching unit based on the switching data and the configuration information to obtain the expected switching result, and to determine whether the data switching result under test meets the switching requirements based on the expected switching result, thereby obtaining the verification result of the TST switching circuit module under test.

[0010] The input and output terminals of the TST data proxy component are connected to the first input and output terminals of the TST switching circuit module under test through the TST switching data interface, and the second output terminal is connected to the first input terminal of the switching data scoring board component. The input and output terminals of the configuration information control proxy component are connected to the second input and output terminals of the TST switching circuit module under test through their respective configuration information interfaces, and the second output terminal is connected to the second input terminal of the switching data scoring board component.

[0011] Secondly, embodiments of the present invention provide a UVM-based TST circuit switching module verification system, including the apparatus as described in the first aspect and the TST switching circuit module under test.

[0012] Thirdly, embodiments of the present invention provide a UVM-based TST circuit switching module verification method, which is applied to the system described in the second aspect, and includes:

[0013] Invoke the TST data broker component to generate exchange data based on test cases;

[0014] The configuration information control agent component is invoked to generate configuration information based on the test cases;

[0015] The TST data proxy component and the configuration information control proxy component are invoked to monitor the data transmission status of each interface of the TST switching circuit module under test, and the configuration information transmission result and the data exchange result under test are obtained.

[0016] The switching data scoring board component is invoked to simulate the logic implementation of the switching unit to obtain the expected switching result. Based on the expected switching result, it is determined whether the transmission result of the configuration information and the switching result of the data under test meet the switching requirements, and the verification result of the TST switching circuit module under test is obtained.

[0017] The beneficial effects of this invention compared to existing technologies are as follows: The device provided by this invention can integrate an advanced UVM verification platform that combines data transmission, processing, and inspection. The integrated TST switching data proxy component and the TST switching configuration information control proxy component at each level have good portability. Furthermore, through the integrated TST switching configuration information control proxy component at each level, various test cases can be used to achieve different types of randomization, such as complete configuration or incremental configuration of configuration information. Verifying the TST circuit switching module using this device ensures the accuracy and completeness of the verification. Compared to traditional technologies, this invention not only enables the verification of the TST circuit switching module, but also improves the flexibility of verification, reduces configuration costs, and increases code and functional coverage by adopting the UVM verification environment, while ensuring improved verification efficiency and completeness.

[0030] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0031] Example 1

[0032] Figure 1 The diagram shown is a structural schematic of a TST circuit switching module provided in an embodiment of the present invention.

[0033] In one example, see Figure 1 The TST circuit switching module mainly consists of the following switching units: Class A time-division switching unit, Class S space-division switching unit, and Class B time-division switching unit.

[0034] For example, each switching unit in the TST circuit switching module may include a data switching module and a configuration information control module.

[0035] Specifically, the TST circuit switching module can receive exchanged data and configuration information and transmit them to the corresponding switching unit. Each switching unit can control the data exchange module in the switching unit to perform data exchange according to the configuration information.

[0036] Example 2

[0037] Figure 2 The diagram shown is a structural schematic of a UVM-based TST circuit switching module verification device provided in an embodiment of the present invention. As an example and not a limitation, the device 200 may include at least a TST data proxy component 210, multiple configuration information control proxy components 220, and a data switching scoring board component 230.

[0038] For example, see Figure 2 Various components in device 200, such as TST data proxy component 210, multiple configuration information control proxy components 220, and exchange data scoring board component 230, can constitute the verification environment (tst_sw_env) of device 200. Above the verification environment level, device 200 can also include a test case base class (base_test), which can include multiple test cases in addition to the verification environment.

[0039] For example, the configuration information control agent component 220 can correspond one-to-one with the switching unit in the TST circuit switching module under test. For example, the configuration information control agent component 220 can include a Class A time-division switching configuration information control agent component, a Class S space-division switching configuration information control agent component, and a Class B time-division switching configuration information control agent component.

[0040] In some embodiments, the test case base class can derive various test cases. The TST data proxy component 210 can generate exchange data according to the test cases and input this exchange data to the TST switching circuit module under test, enabling it to perform data exchange. The configuration information control proxy component 220 can generate configuration information for the corresponding switching unit according to the test cases, then transmit this configuration information to the corresponding switching unit and monitor the transmission result of the configuration information. The TST data proxy component 210 can also monitor the transmission process of the exchange data to obtain the exchange result of the data under test. The exchange data scoring board component 230 can simulate the logical implementation of the switching unit according to the exchange data and configuration information, generate the expected exchange result, and determine whether the exchange result of the data under test meets the exchange requirements based on the expected exchange result, thereby obtaining the verification result of the TST circuit switching module under test.

[0041] For example, see Figure 2 The input and output ports of the TST data proxy component 210 can be connected via the TST data exchange interface (see...). Figure 2 The first input / output terminal of the TST switching circuit module under test (tst_data_if) is connected to the second output terminal of the switching data scoring board component 230, and the second output terminal is connected to the first input terminal of the switching data scoring board component 230. The input / output terminals of the configuration information control agent component 220 can be connected through their respective configuration information interfaces (see [link to configuration information]). Figure 2 The configuration information interfaces at_cfg_if (Class A time-division switching unit), s_cfg_if (Class S space-division switching unit), and bt_cfg_if (Class B time-division switching unit) are connected to the second input / output terminals of the TST switching circuit module under test. The second output terminal is connected to the first input terminal of the switching data scoring board assembly 230.

[0042] Specifically, see Figure 2 The TST circuit switching module under test and the various components inside the device 200 can transmit data through the connected interfaces. For example, the device 200 can transmit data with the TST circuit switching module (i.e., the design under test DUT) through the TST data exchange interface, transmit configuration information to each switching unit through the configuration information interface, and then each switching unit controls the switching unit to realize the data exchange process according to the configuration information.

[0043] In one possible implementation, see Figure 3 The TST data agent component 210 may include a TST data sequence generator 211, a TST data driver 212, and a TST data interface monitor 213.

[0044] For example, the TST data sequence generator 211 can generate different exchange data sequences according to different test cases, and then transmit them to the TST data driver 212. The TST data driver 212 can drive the obtained exchange data to the TST exchange data interface (tst_data_if), and then send it to the DUT to simulate real data transmission. The TST data interface monitor 213 can monitor the input and output of exchange data in the DUT to obtain the exchange result of the data under test, and transmit the result to the exchange data scoring board component.

[0045] In one possible implementation, the configuration information control agent components at each level have the same structure and similar working logic, only differing in the objects they execute. For example, the A-level time-division switching configuration information control agent component is used to generate the configuration information for the A-level time-division switching unit, and the S-level space-division switching configuration information control agent component is used to generate the configuration information for the S-level space-division switching unit.

[0046] Specifically, see Figure 4 The configuration information control agent component 220 may include a T-switch configuration sequence generator 221, a T-switch configuration driver 222, and a T-switch configuration interface monitor 223.

[0047] For example, the T-switching configuration sequence generator 221 can generate a set of configuration information based on the randomized configuration of the test cases. The T-switching configuration driver 222 can drive the configuration information to the corresponding configuration information interface according to the storage location of the configuration information of each level of switching unit in the switching reference model component of the switching data scoreboard component 230. The T-switching configuration interface monitor 223 can continuously monitor the input and output of the DUT to these configuration information on the configuration information interface and send the monitoring results (i.e., the transmission results of the configuration information) to the switching data scoreboard component 230.

[0048] In one example, configuration information may include a set of configuration data frames and exchange relationship switching signals.

[0049] For example, a configuration data frame can be a set of complete data frames and / or a set of incremental configuration signals.

[0050] For example, if the TST circuit switching module under test supports uninterrupted switching and incremental configuration functions, the configuration information can include a complete configuration data frame, incremental configuration information transmission transactions (i.e., incremental configuration signals), and switching signals.

[0051] In one possible implementation, see Figure 2 The exchange data scoreboard component 230 can embed an exchange reference model component (tst_sw_refmod) 231 and an exchange data comparison component 232.

[0052] For example, the switching reference model component 231 can receive switching data from the TST data proxy component and configuration information from each configuration information control proxy component. Based on the configuration information, it performs TST switching on the input switching data to obtain the desired switching result. Then, it inputs the desired switching result to the switching data comparison component 232. The switching data comparison component 232 can compare the desired switching result with the test data switching result, perform statistical analysis and printing on the results, determine whether the test data switching result meets the switching requirements, and obtain the verification result of the TST switching circuit module under test.

[0053] Specifically, the data exchange scoring board component 230 can write configuration information into the data exchange reference model component 231 to control the exchange of data and simulate the logic in real hardware.

[0054] In one example, see Figure 2 All agent components monitoring the top-level input and output data of the DUT can transmit the results to the exchange data scoreboard component 230, such as the TST data agent component and all configuration information control agent components, through Transaction Level Modeling (TLM). Data exchange within the verification environment can also be achieved through TLM.

[0055] In some embodiments, see Figure 2 The device 200 may also include a function coverage group definition component 240. This component can be used to determine whether the data on each interface covers the function points defined in the coverage group, that is, to determine whether the data on each interface is written correctly.

[0056] For example, the input / output terminals of the functional coverage group definition component 240 can be connected to the third input / output terminal of the TST switching circuit module under test via the coverage group monitoring interface (cover_if).

[0057] Specifically, the function coverage group definition component 240 defines some function points that need to be verified according to different system requirements, and then judges whether the defined function points are covered by monitoring the data on the monitoring interface (cover_if) of the coverage group and the data changes.

[0058] For example, the components within device 200 can be built using the SystemVerilog language.

[0059] In some embodiments, users can also write a makefile, select the compilation tools, link the DUT file list filelist and the verification environment file list filelist, add compilation macros, etc. Through this makefile script, the test cases can also be run automatically a specified number of times. Specifically, the number of runs can be set through the makefile script, and the system can be started to automatically execute the simulation verification for the corresponding number of runs.

[0060] The device provided by this invention is an advanced UVM verification platform that integrates data transmission, processing, and inspection. The integrated TST switching data proxy component and TST switching configuration information control proxy components at all levels have good portability. Furthermore, through the integrated TST switching configuration information control proxy components at all levels, various test cases can be used to achieve different types of randomization, such as complete configuration or incremental configuration of configuration information. Verifying the TST circuit-switched module using this device ensures the accuracy and completeness of the verification. Compared to traditional technologies, this invention not only enables the verification of the TST circuit-switched module, but also improves verification flexibility, reduces configuration costs, and increases code and functional coverage by employing a UVM verification environment, while simultaneously ensuring improved verification efficiency and completeness.

[0061] Traditional UVM verification devices typically only simulate single-level logic, failing to accurately reproduce the cascading effect of three-level switching, and are unable to simulate the process of configuration information being distributed step-by-step from each level of switching unit in the TST module. Furthermore, they struggle to generate mixed transaction sequences containing complete configuration, incremental configuration, and switching signals. Consequently, traditional UVM verification devices often suffer from insufficient data comparison accuracy and difficulty in capturing cross-level timing errors or configuration conflicts when verifying TST circuit switching modules.

[0062] This invention controls proxy components by setting configuration information corresponding one-to-one with the switching units. Each component independently generates and determines the configuration information of the corresponding switching unit, and supports mixed transaction injection of complete configuration, incremental configuration and switching signals. This ensures dynamic collaborative verification of multi-level configuration of the TST circuit switching module. By setting TST data proxy components, it can support randomized generation and dynamic driving of multi-channel data frames. Through parameterized design to adapt to different channel scales, it can simulate the timing synchronization problem of the TST circuit switching module in high-concurrency scenarios.

[0063] Furthermore, through the reference model component embedded in the scoring board component, it is possible to accurately simulate the cascaded logic of Class A time-division switching, Class S space-division switching and Class B time-division switching, receive input data and configuration information synchronously with the DUT, generate expected results consistent with hardware behavior, and achieve the zero-error requirement for cross-level data comparison.

[0064] It should be understood that each component in the aforementioned device 200 can be implemented entirely or partially through software, hardware, or a combination thereof. These components can be embedded in hardware or independently of a device with data processing capabilities, or stored in software within the memory of the aforementioned device, so that the processor can invoke and execute the operations corresponding to each of the above modules. The aforementioned device can be, but is not limited to, various types of chip verification computers already existing in the art.

[0065] Example 3

[0066] Figure 5 The diagram shown illustrates the structure of a UVM-based TST circuit switching module verification system according to an embodiment of the present invention. As an example and not a limitation, system 500 may include the TST switching circuit module shown in Embodiment 1 as the TST switching circuit module under test, and may also include the UVM-based TST circuit switching module verification device 200 shown in Embodiment 2.

[0067] For example, the apparatus 200 can be used to test the TST switching circuit module under test to verify whether its data switching function meets the requirements.

[0068] The specific structure and function of the device 200 and the TST switching circuit module under test can be found in Embodiments 2 and 1 above, respectively, and will not be repeated here.

[0069] Example 4

[0070] Figure 6 The diagram illustrates an implementation flowchart of a UVM-based TST circuit switching module verification method provided by an embodiment of the present invention. This method can be applied to the system shown in Embodiment 3 above, and may include the following steps S601-S605, which are described below.

[0071] S601, power on and initialize the UVM-based TST circuit switching module verification system.

[0072] In one possible implementation, if the system has already been initialized before this test and this is not the first test, then step S602 can be performed directly. If this is the first test, then step S601 must be started to initialize the device 200 and the TST circuit switching module in the system.

[0073] In one example, all random access memories (RAMs) in the system can be manually initialized before starting testing, and then configuration information can be written to them in subsequent processes. For instance, the switching reference model component 231 needs to be reset, and the various RAMs in the TST circuit switching module need to be initialized before configuration information can be written to them.

[0074] S602, invokes the TST data broker component to generate exchange data based on test cases.

[0075] In one example, before invoking the TST data proxy component 210, multiple configuration information control proxy components can be invoked to generate initial configuration information conforming to the driver protocol requirements and sent to the TST circuit switching module through the corresponding interfaces. The TST circuit switching module can then configure all switching control memories based on the initial configuration information. Afterwards, the TST data proxy component 210 can be invoked to generate switching data.

[0076] In one example, the TST data proxy component 210 can be invoked to generate exchange data frames and drive these exchange data onto the TST exchange data interface to complete the input of exchange data.

[0077] S603 invokes the configuration information control agent component to generate configuration information based on test cases.

[0078] In one example, after the input exchange data begins, the proxy component can be controlled to generate subsequent configuration information based on the test case configuration, in order to achieve the most complete verification and coverage collection possible.

[0079] For example, if the TST circuit switching module is a 40-port TST switching circuit, when generating configuration information, it needs to wait until all control memories in the TST circuit switching module have written a complete set of configuration data frames before it can generate the switching data transmission signal and the incremental configuration signal. Only after all control memories have written two complete sets of configuration data frames can it begin generating the switching relationship switching signal.

[0080] S604 calls the TST data proxy component and configuration information control proxy component to monitor the data transmission status of each interface of the TST switching circuit module under test, and obtains the configuration information transmission result and the data exchange result under test.

[0081] In one example, the data exchange result of the data to be tested can be obtained by monitoring the data transmission of the TST exchange data interface through the TST data proxy component, and the transmission result of the configuration information can be obtained by monitoring the data transmission of the configuration information interface through the configuration information control proxy component.

[0082] S605 calls the data switching board component to simulate the logic implementation of the switching unit to obtain the expected switching result, and determines whether the transmission result of the configuration information and the switching result of the data under test meet the switching requirements based on the expected switching result, and obtains the verification result of the TST switching circuit module under test.

[0083] In one example, if the result of the data exchange to be tested does not meet the requirements, the verification can end after printing the simulation log of the failed data comparison.

[0084] In another example, if the data exchange results meet the requirements, the verification can end after printing the simulation log of successful data comparison.

[0085] The method provided by this invention constructs a module-level TST circuit switching module verification system, thereby supporting the use of the design code module of the TST circuit switching module to be verified as the verification object, eliminating the need to integrate the entire chip as the design under test. Therefore, only the TST circuit switching module itself needs to be integrated as the design under test, thus reducing the dependency on the design under test and allowing for earlier execution of verifiable nodes. Since the entire electronic control unit chip or other design components are no longer required, the system can begin verification during the design phase of the TST circuit switching module, significantly advancing the verification intervention time and reducing dependencies. Furthermore, the system incorporates different switching function modes, thereby generating random configuration or switching data to effectively complete the functional modes within the TST circuit switching module, ultimately achieving randomness and completeness of the TST circuit switching module's excitation, significantly improving the verification quality of the TST circuit switching module.

[0086] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.
