Description

Technical Field

[0001] The present invention relates to the field of chip verification technology, and in particular to a register configuration method, device, equipment and medium. Background Art

[0002] With the rapid development of artificial intelligence applications, the integration scale and design complexity of high-performance computing chips are increasing day by day. In order to achieve higher integration, the number of instantiations of the same circuit module in the chip is increasing exponentially. In order to save bus address resources and adapt to various usage scenarios, the registers in the instantiation of multiple copies of the circuit module share a set of register address segments. The design method of coexistence of broadcast access mode and gated module access mode has become an important means for chips to obtain better performance and customization.

[0003] During the chip verification process, by verifying the registers, it can be ensured that the registers can correctly store and transmit data in the entire system and meet the design specifications and functional requirements.

[0004] In the traditional register verification method, the register information in each circuit module is generally maintained through a pre-generated register model. However, since the register lists of multiple instantiated circuit modules are the same, and one address in the register model can only store the attribute value of one register, the traditional register model can only be used for register verification of circuit modules that are not instantiated in multiple copies, and cannot be used for register verification of multiple instantiated circuit modules. In the prior art, if registers in multiple instantiated circuit modules in a broadcast access mode are to be verified, it is necessary to establish a special test case to test broadcast access-related functions, which reduces the real-time and coverage of the verification. When the number of instantiated circuit modules is large or the number of registers is large, the register attribute array will also increase geometrically, and the maintenance challenge of the verification platform will also increase. Summary of the invention

[0005] The present invention provides a register configuration method, device, equipment and medium, which can realize register verification of multiple instantiated circuit modules and reduce the complexity of the verification platform.

[0006] According to one aspect of the present invention, a register configuration method is provided, which is executed by a register control module and a register comparison module in a chip verification platform, and includes:

[0007] When it is determined through the register control module that the acquired register operation instruction is a register configuration transaction issued by the front door, the register operation instruction is sent to the register model, and the register information of the register to be configured returned by the register model is acquired;

[0008] Generate a register configuration transaction according to the register information and the register operation instruction through a register control module, and send the register configuration transaction to the system under test so that the system under test can perform attribute configuration on the register to be configured;

[0009] By means of a register control module, updating the attribute of the register to be configured in the register model or the additional register model according to the register information and the register operation instruction;

[0010] Through the register comparison module, when the system under test is monitored to perform register configuration operations, attribute comparison is performed according to the interface information, register model and additional register model of the system under test.

[0011] According to another aspect of the present invention, a register configuration device is provided, which is executed by a register control module and a register comparison module in a chip verification platform, and includes:

[0013] A configuration transaction issuing unit, configured to generate a register configuration transaction according to the register information and the register operation instruction through a register control module, and send the register configuration transaction to the system under test so that the system under test can perform attribute configuration on the register to be configured;

[0014] A register attribute maintenance unit, configured to update the attribute of the register to be configured in the register model or the additional register model according to the register information and the register operation instruction through the register control module;

[0015] The attribute comparison unit is used to perform attribute comparison according to the interface information, register model and additional register model of the system under test through the register comparison module when monitoring the system under test to perform register configuration operation.

[0020] According to another aspect of the present invention, a computer-readable storage medium is provided, wherein the computer-readable storage medium stores computer instructions, and the computer instructions are used to enable a processor to implement the register configuration method described in any embodiment of the present invention when executed.

[0021] The technical solution of the embodiment of the present invention is to send the register operation instruction to the register model and obtain the register information through the register control module when it is determined that the register configuration transaction sent by the front door is obtained, generate the register configuration transaction through the register control module, and send the register configuration transaction to the system to be tested, update the attributes of the register to be configured in the register model or the additional register model through the register control module, and perform attribute comparison according to the interface information, register model and additional register model of the system to be tested when the system to be tested is monitored to perform the register configuration operation through the register comparison module.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0034] Embodiment 1

[0035] Figure 1This is a flow chart of a register configuration method provided in the first embodiment of the present invention. This embodiment is applicable to the case of real-time verification of register configuration in a chip. The method can be executed by a register configuration device. The register configuration device can be implemented in the form of hardware and / or software and can generally be configured in a chip verification platform with data processing functions. Figure 1 As shown, the method includes:

[0036] S110. When it is determined through the register control module that the acquired register operation instruction is a register configuration transaction issued by the front door, the register operation instruction is sent to the register model, and register information of the register to be configured returned by the register model is acquired.

[0037] Optional, Figure 2 The structure diagram of a chip verification platform provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the chip verification platform includes a register control module, a register comparison module, a register model, an additional register model and a system to be tested.

[0038] Optionally, the system to be tested may refer to a chip to be verified, and the system to be tested includes multiple circuit modules, which may be uninstantiated multiple circuit modules or instantiated multiple circuit modules, and the circuit modules may include multiple registers. Since in most usage scenarios, the configuration values ​​of the registers in the instantiated multiple circuit modules are the same, if each instantiated multiple circuit module is assigned an independent address, it will greatly occupy the address space of the control bus and affect the address allocation. Therefore, in the currently designed chips, the register lists in the instantiated multiple circuit modules are the same.

[0039] Furthermore, the register model is generated by the verification platform according to the register list of the chip, so one address in the register model only stores the data of one register.

[0040] Figure 3 FIG. 1 is a schematic diagram of the structure of an existing chip verification platform. Figure 3As shown, the existing chip verification platform only includes a register model, a register processing module, and a system to be tested. When registers are configured according to the existing chip verification platform, the register model cannot maintain all register properties of multiple instantiated circuit modules. Therefore, in the prior art, a test case is generally established, and then an attribute array of multiple instantiated circuit modules is established in the test case to save the attribute values ​​of multiple instantiated circuit modules. However, through the test case method, it is impossible to monitor any register access in real time like the register model, which reduces the real-time and coverage of the verification. If the number of instantiated circuit modules is large or the number of registers is large, the register attribute array will increase geometrically, the complexity is high, and the maintenance challenge of the verification platform will also increase.

[0041] Figure 4 is a schematic diagram of an optional register model. Figure 4 As shown, the chip includes circuit modules A and E that are not instantiated in multiple copies, and also includes circuit modules B, C, and D that are instantiated in multiple copies. Among them, the registers of circuit modules B1, circuit modules B2, ..., and circuit modules Bn share a section of register addresses, the registers of circuit modules C1, circuit modules C2, ..., and circuit modules Cm share a section of register addresses, and the registers of circuit modules D1, circuit modules D2, ..., and circuit modules Dp share a section of register addresses.

[0042] In an optional example, when circuit module B is instantiated as circuit module B1, circuit module B2, ..., circuit module Bn, if circuit module B1 includes register 1, register 2, and register 3, then circuit module B2, ..., circuit module Bn also include register 1, register 2, and register 3. This is only for illustrative purposes.

[0043] Optionally, in order to solve the problem in the prior art that an address in a register model can only save the attribute value of one register and can only be used for register verification of circuit modules that are not instantiated in multiple copies, the present invention proposes a method of adding an additional register model to the chip verification platform to maintain the register information of multiple instantiated circuit modules through the additional register model.

[0044] Optionally, the front door sending the register configuration transaction may refer to sending the register configuration transaction to the system under test through a standardized manner such as an interface or a communication channel.

[0045] Optionally, in the register model proposed in the present invention, the register model can maintain register information and attribute values ​​of non-instantiated multiple circuit modules. At the same time, the register model also includes register information of instantiated multiple circuit modules. The register information may be information such as address, name, circuit module, whether the circuit module is an instantiated multiple circuit module, etc., but the register model does not maintain register attributes of instantiated multiple circuit modules. The additional register model is not restricted by address. The additional register model can maintain register attributes of instantiated multiple circuit modules, and the registers in the instantiated multiple circuit modules are all identified by register names. For example, the additional register can maintain circuit module B2, register x, and attribute value.

[0046] Optionally, the register operation instruction may include the name or address of the register to be configured, and may also include the attribute value to be configured of the register to be configured, so that the original attribute value of the register to be configured in the chip is replaced according to the attribute value in the register operation instruction.

[0047] Optionally, after the register control module receives the register operation instruction, the register operation instruction is sent to the register model, so that the register model obtains the register information of the register to be configured in the register model according to the register name or address in the register operation instruction, and returns the register information of the register to be configured to the register control module.

[0048] Optionally, the returned register information of the register to be configured may include the address of the register to be configured, information of the circuit module to which the register to be configured belongs, and the name of the register to be configured. If the register to be configured belongs to multiple instantiated circuit modules, the returned register information of the register to be configured may also include selection module information in the circuit module to which the register to be configured belongs.

[0049] S120 , generating a register configuration transaction according to the register information and the register operation instruction through the register control module, and sending the register configuration transaction to the system under test, so that the system under test can perform attribute configuration on the register to be configured.

[0050] Optionally, through the register control module, after obtaining the register address of the register to be configured, the target attribute values ​​of each attribute to be configured of the register to be configured can be determined according to the register operation instruction, the register address and the target attribute value can be combined to generate a register configuration transaction, and the register configuration transaction can be sent to the system to be tested, so that the system to be tested can determine the register to be configured according to the register address, and update the attribute value of the register to be configured to the target attribute value.

[0051] Optionally, for a circuit module that is instantiated in multiple copies, a selection module may be included, and the selection module may be used to configure the circuit module into a broadcast access mode or a gated module mode.

[0052] Optionally, if the circuit module is configured as a broadcast access mode, an address may correspond to a register of the same name in each of the multiple instantiated circuit modules. For example, when circuit module B is not instantiated in multiple copies, address adress_0 may correspond to register x in circuit module B. When circuit module B is instantiated into circuit module B1, circuit module B2, ..., circuit module Bn, address adress_0 may correspond to register x in each of circuit modules in circuit module B1, circuit module B2, ..., circuit module Bn.

[0053] Optionally, if the circuit module is configured as a gated module, an address only corresponds to a specified register in one of the multiple instantiated circuit modules, and the specific corresponding circuit module can also be configured through the selection module. For example, for the multiple instantiated circuit module B, the address adress_0 can be configured in the selection module to correspond to the register x in the circuit module B2.

[0054] Furthermore, if the register to be configured in the register configuration transaction received by the system under test belongs to an uninstantiated multiple circuit module, it can be configured directly according to the register address and the target attribute value of the register to be configured; if the register to be configured belongs to an instantiated multiple circuit module, and the circuit module is configured as a broadcast access mode, then each register belonging to the register address is configured according to the target attribute value; if the register to be configured belongs to an instantiated multiple circuit module, and the circuit module is configured as a broadcast access mode, then the register specified in the selection module for the register address is configured according to the target attribute value.

[0055] S130 , updating the attributes of the register to be configured in the register model or the additional register model according to the register information and the register operation instruction through the register control module.

[0056] Optionally, in order to verify the reliability and accuracy of the register configuration, it is necessary to maintain the attribute values ​​of the registers to be configured in the register model or the additional register model while sending the register configuration transaction to the system under test, so as to facilitate subsequent viewing or comparison of the register attributes.

[0057] Optionally, through the register control module, it is determined whether the register to be configured belongs to the instantiated multiple circuit modules; if not, the corresponding register is directly determined in the register model according to the register address or name, and the attribute value of the register in the register model is updated according to the target attribute value; if it does, at least one register is determined in the additional register model, and the register attribute determined in the additional register model is updated using the target attribute value.

[0058] Furthermore, if the register to be configured belongs to multiple instantiated circuit modules, then based on the information of the circuit module to which the register to be configured belongs, it is determined whether the circuit module to which the register to be configured belongs is in broadcast access mode or module selection mode. If it is a broadcast access mode, then the names of all instantiated circuit modules of the circuit module and the names of the registers to be configured are determined, and all registers in the additional register model that match the names of the instantiated circuit modules and the names of the registers to be configured are updated to target attribute values; if it is a module selection mode, it is also necessary to obtain the target instantiated circuit module corresponding to the module selection mode, and update the register corresponding to the name of the register to be configured in the target instantiated circuit module in the additional register model to the target attribute value.

[0059] S140 , when the register configuration operation of the system under test is monitored, a register comparison module performs an attribute comparison according to the interface information, register model and additional register model of the system under test.

[0060] Optionally, the register configuration operation on the interface of the system under test can be monitored in real time through the register comparison module. When the interface information in the register configuration interface of the system under test is read, it is determined that the register configuration operation of the system under test is monitored.

[0061] Optionally, when a register configuration operation is monitored, the interface information can be parsed to obtain the register properties and register address of the current configuration register in the system under test, and the register address can be sent to the register model again to obtain the register information fed back by the register model to the register comparison module.

[0062] Furthermore, after obtaining the register information, it is first necessary to determine whether it belongs to a register of multiple instantiated circuit modules. If it belongs to a register of multiple instantiated circuit modules, the backdoor reads the status of the selection register to determine whether it is a broadcast access mode or a module access mode, and then obtains the attribute values ​​of the corresponding register from the additional register model and compares them with the monitored register configuration to complete the closed-loop check of the register. If it belongs to a register of multiple circuit modules that are not instantiated, the attribute values ​​of the register in the register model are obtained and compared with the attribute values ​​obtained by parsing the interface information.

[0063] The technical solution of the embodiment of the present invention is to send the register operation instruction to the register model and obtain the register information through the register control module when it is determined that the register configuration transaction sent by the front door is obtained, generate the register configuration transaction through the register control module, and send the register configuration transaction to the system to be tested, update the attributes of the register to be configured in the register model or the additional register model through the register control module, and perform attribute comparison according to the interface information, register model and additional register model of the system to be tested when the system to be tested is monitored to perform the register configuration operation through the register comparison module. The method does not affect the use of registers by the existing test platform, is compatible with the original register access method, has portability and promotion, and can replace test cases, simplifies the complexity of the test platform, and makes the overall architecture of the test platform clearer. The register information can be monitored in real time, which improves the accuracy and speed of register verification, and effectively solves the difficult problem of verifying the coexistence of a set of register models and register address segments, broadcast access methods and gating module access methods in multiple circuit modules in chip verification.

[0064] Embodiment 2

[0065] Figure 5 This is a flow chart of a register configuration method for sending register configuration transactions by the front door provided in the second embodiment of the present invention. This embodiment specifically describes the register configuration method for sending register configuration transactions by the front door based on the above embodiments. Figure 5 As shown, the method includes:

[0066] S210. When it is determined through the register control module that the acquired register operation instruction is a register configuration transaction issued by the front door, the register operation instruction is sent to the register model, and register information of the register to be configured returned by the register model is acquired.

[0067] Optionally, the register information of the register to be configured includes the register address of the register to be configured, the first circuit module information of the first circuit module to which the register to be configured belongs, and the first register name; when the register to be configured belongs to multiple instantiated circuit modules, the register information of the register to be configured also includes the first selection module information of the first circuit module.

[0068] Optionally, the first circuit module may refer to the circuit module to which the register to be configured in the register operation instruction belongs, the first register name is the register name of the register to be configured, and the first circuit module information includes the first circuit module name and whether the first circuit module is a circuit module for routine multiple copies.

[0069] S220, determining target attribute values ​​of various attributes of the register to be configured according to the register operation instruction through the register control module, and generating a register configuration transaction according to the register address of the register to be configured and the target attribute values ​​of various attributes.

[0070] S230 . Send the register configuration transaction to the system under test through the register control module, so that the system under test can perform attribute configuration on the register to be configured.

[0071] Optionally, when a register configuration transaction is sent to the front door, the register configuration transaction is sent to the system under test through an interface in the system under test.

[0072] S240 , updating the attributes of the register to be configured in the register model or the additional register model according to the register information and the register operation instruction through the register control module.

[0073] Optionally, the chip verification platform only needs to customize an additional register list for instantiating multiple circuit modules, and then use the automated tool ralgen to generate an additional register model. The additional register model stores the attribute values ​​of the registers of each instantiated circuit module, and there is no need to manually create an array for maintenance.

[0074] The advantage of this setting is that it breaks through the address restrictions of the register model and increases the portability and maintainability of the verification platform. If there are modifications to the registers or circuit modules, you only need to modify the additional register list to complete the update of the additional register model.

[0075] Wherein, updating the attribute of the register to be configured in the register model or the additional register model through the register control module according to the register information and the register operation instruction may include any of the following:

[0076] By means of the register control module, when it is determined according to the first circuit module information that the register to be configured belongs to the uninstantiated multiple copies of the circuit module, the first register to be configured is located in the register model according to the first register name or register address, and each attribute array of the first register to be configured is updated using the target attribute value;

[0077] Through the register control module, when it is determined according to the first circuit module information that the register to be configured belongs to the instantiated multiple circuit modules, the attribute of the register to be configured is updated in the additional register model according to the register information and the register operation instruction.

[0078] Optionally, the properties of uninstantiated multiple circuit modules are maintained in the register model. The register model stores the name, address, circuit module name, whether the circuit module is an instantiated circuit module, and register attribute array of the registers in the uninstantiated multiple circuit modules. After determining the address or name of the register of the uninstantiated multiple circuit modules, the attribute array of the register can be directly located in the register model.

[0079] Optionally, the first register name is a combination of a module name of a circuit module to which the register belongs and a register name, for example, circuit module B2 register x. This naming method can accurately locate the register in the register model and the additional register model.

[0080] Optionally, if the register to be configured belongs to a circuit module that has not been instantiated in multiple copies, the first register to be configured may be directly located in the register model according to the first register name or register address.

[0081] Among them, when it is determined through the register control module that the register to be configured belongs to the instantiated multiple circuit modules according to the first circuit module information, the attribute of the register to be configured is updated in the additional register model according to the register information and the register operation instruction, which may include:

[0082] By means of the register control module, when it is determined according to the first circuit module information that the register to be configured belongs to the instantiated multiple copies of the circuit module, the register configuration mode of the first circuit module is determined according to the first selection module information to be the broadcast access mode or the gated module mode;

[0083] Through the register control module, if the register configuration mode is a broadcast access mode, multiple second registers to be configured are located in the additional register model according to the first register name, and each attribute array of each second register to be configured is updated respectively by using the target attribute value; wherein each second register to be configured belongs to each instantiated circuit module of the first circuit module;

[0084] Through the register control module, if the register configuration mode is the selection module mode, the first instantiated circuit module in the first circuit module is determined according to the first selection module information, and the third register to be configured is located in the additional register according to the first register name and the first instantiated circuit module, and the attribute arrays of the third register to be configured are updated using the target attribute value.

[0085] Optionally, the register model also maintains the address, name, name of the circuit module to which each register of the instantiated circuit module belongs, whether the circuit module is an instantiated circuit module, and whether the register configuration mode is a broadcast access mode or a gated module mode. If it is a gated module mode, it also includes the module name specified by the gated module. After obtaining the above information in the register model, the attribute array of the register can be located in the additional register model. In the additional register model, each register information includes the register name and the attribute array.

[0086] Optionally, if it is for multiple instantiated circuit modules, a register address corresponds to a register with the same name in each of the multiple instantiated circuit modules, and the first register name may include a specified register in each of the multiple instantiated circuit modules, for example, it may be circuit module B1 register x, circuit module B2 register x,..., circuit module Bn register x.

[0087] Optionally, if the access mode is broadcast, each register belonging to the first register name in the additional register model is determined as the second register to be configured.

[0088] Optionally, if it is a module selection method, the first instantiated circuit module specified in the instantiated multiple circuit modules is determined according to the first selection module information, for example, the circuit module B2 in each instantiated circuit module of the specified circuit module B. At this time, the first register name matching the first segment instantiated circuit module is determined in the first register name, for example, the circuit module B2 register x, and then the third register to be configured is determined in the additional register according to the first register name matching the first instantiated circuit module.

[0089] S250. Through the register comparison module, when it is monitored that the system under test is performing a register configuration operation, the interface information of the system under test is parsed to obtain the target address of the current configuration register in the system under test and the first attribute value of each attribute of the current configuration register, and send the target address to the register model to obtain the register information of the current configuration register returned by the register model.

[0090] Optionally, the first attribute value may refer to the attribute value obtained by parsing the interface information, and the target address may refer to the address of the current configuration register of the system to be tested. After sending the target address to the register model, the register information of the current configuration register fed back by the register model may be obtained, which may include the name and address of the current configuration register, the name of the circuit module to which it belongs, and whether the circuit module is a multiple-copy circuit module for instantiation. If it is a multiple-copy circuit module for instantiation, the register information of the current configuration register also includes whether the register configuration mode is a broadcast access mode or a gate module mode. If it is a gate module mode, it also includes the module name specified by the gate module.

[0091] S260 . Performing attribute comparison with the register model or the additional register model according to the register information of the current configuration register and the first attribute value through the register comparison module.

[0092] Among them, the register information of the current configuration register includes the second register name of the current configuration register, the second circuit module information of the second circuit module to which the current configuration register belongs, and the second selection module information of the second circuit module; if the second circuit module belongs to an uninstantiated multiple circuit module, the register information of the current configuration register also includes the second attribute value of each attribute of the current configuration register stored in the register module.

[0093] Optionally, performing attribute comparison with the register model or the additional register model according to the register information of the current configuration register and the first attribute value by the register comparison module may include any of the following:

[0094] By the register comparison module, when it is determined according to the second circuit module information that the current configuration register belongs to a circuit module that has not been instantiated multiple times, the first attribute value is compared with the second attribute value to obtain a comparison result of the register configuration;

[0095] When it is determined through the register comparison module that the current configuration register belongs to the instantiated multiple circuit modules according to the second circuit module information, a property comparison is performed with the additional register model according to the register information of the current configuration register and the first property value.

[0096] Optionally, if the currently configured register belongs to a circuit module that is not instantiated in multiple copies, the second attribute value of the register can be directly used in the register model. The second attribute value is the attribute value of the register saved in the register model. If the first attribute value is the same as the second attribute value, it is determined that the configuration value of the register in the register model is the same as that in the system to be tested, thereby completing a closed-loop check of the register configuration.

[0097] Optionally, when it is determined through the register comparison module that the current configuration register belongs to the instantiated multiple circuit modules according to the second circuit module information, performing attribute comparison with the additional register model according to the register information of the current configuration register and the first attribute value may include:

[0098] When it is determined by the register comparison module that the current configuration register belongs to the instantiated multiple copies of the circuit module according to the second circuit module information, the register configuration mode of the second circuit module is determined to be the broadcast access mode or the gated module mode according to the second selection module information;

[0099] Through the register comparison module, if the access mode is broadcast, the attribute values ​​of multiple first registers are obtained in the additional register model according to the second register name, and the attribute values ​​of each first register are respectively compared with the first attribute value to obtain the comparison result of the register configuration; wherein each first register belongs to each instantiated circuit module of the second circuit module;

[0101] Optionally, if the currently configured register belongs to a circuit module that is instantiated in multiple copies, a corresponding register is determined in the additional register model based on register information of the currently configured register, and then the attribute value stored in the additional register model is compared with the first attribute value.

[0102] Optionally, the manner of determining the current configuration register in the additional register model according to the register information of the current configuration register is similar to the manner of determining the register to be configured in the additional register model in step S240, and is not described in detail here.

[0103] The technical solution of the embodiment of the present invention uses a register control module. When it is determined that a register configuration transaction is obtained by the front door, the register operation instruction is sent to the register model and the register information is obtained.

[0104] Embodiment 3

[0105] Figure 6This is a flowchart of a register configuration method for backdoor access to registers provided in Embodiment 3 of the present invention. Based on the above embodiments, this embodiment specifically describes a register configuration method for backdoor access to registers. Figure 6 As shown, the method includes:

[0106] S310. When it is determined through the register control module that the acquired register operation instruction is a backdoor access register, the register operation instruction is sent to the register model, and the second register name of the register to be configured returned by the register model is acquired.

[0107] Optionally, backdoor access to a register may refer to directly obtaining a backdoor access address of a register, thereby directly configuring a property value of the register through the backdoor access address of the register without modifying the register configuration through an interface.

[0108] Optionally, since there is only one register group in the register model, only one register group can be accessed when implementing backdoor access, and backdoor access cannot be performed on other register groups. The backdoor access path is a string type. If backdoor access is to be implemented, it is necessary to save the backdoor access paths of all registers of multiple instantiated circuit modules, such as circuit module B1, circuit module B2,..., circuit module Bn, circuit module C1, circuit module C2,..., circuit module Cm, circuit module D1, circuit module D2,..., circuit module Dp. However, the number of instantiated multiple circuit modules and registers actually set in existing chips is large. If the backdoor access path is saved manually, the workload is extremely large, and it is necessary to go through multi-layer selection and judgment, which is not conducive to the maintenance of the verification platform.

[0109] In the embodiment described in the present invention, the additional register model can provide a backdoor access path for the corresponding registers of each of the instantiated multiple circuit modules. When the register control module receives a module register operation, after instruction analysis and processing, if the operation type is backdoor access, the backdoor access path of the corresponding module register will be obtained directly from the additional register model. The backdoor access operation is completed by calling the built-in backdoor access function of the UVM (Universal Verification Methodology) function library. The introduction of the additional register model solves the problem of the backdoor access path.

[0110] It is understandable that if the backdoor access path is saved in the prior art, then when obtaining the backdoor access path, it is necessary to traverse all the register backdoor access paths to determine the backdoor access path of the register to be configured. By instantiating an additional register model, not only is the problem that the existing register model cannot save the backdoor access paths of each register in multiple circuit modules solved, but also the backdoor access path corresponding to the name can be quickly obtained after the second register name is entered.

[0111] Optionally, the second register name may include the circuit module name to which the register to be configured belongs and the register name.

[0112] S320. Obtain a backdoor access address corresponding to the second register name in the additional register model through the register control module, and determine second attribute values ​​of various attributes of the register to be configured according to the register operation instruction.

[0113] S330 , calling the backdoor access function through the register control module, and performing attribute configuration on the register to be configured in the system under test according to the backdoor access address and the second attribute value.

[0114] Optionally, the backdoor access function may be a backdoor access function built into the UVM function library.

[0115] Optionally, for the backdoor access register, after obtaining the backdoor access address, the register may be directly accessed according to the backdoor access address, and the attribute value of the register may be updated to the second attribute value.

[0116] The technical solution of the embodiment of the present invention utilizes a register control module. When it is determined that the acquired register operation instruction is a backdoor access register, the register operation instruction is sent to the register model, and the second register name of the register to be configured returned by the register model is obtained, and the backdoor access address corresponding to the second register name is obtained in the additional register model, and according to the register operation instruction, the second attribute value of each attribute of the register to be configured is determined, and the backdoor access function is called. According to the backdoor access address and the second attribute value, the attribute configuration of the register to be configured in the system under test is performed. The backdoor access path of the registers in multiple circuit modules can be quickly obtained through the additional register model. For chips with a large number of registers, the workload of chip designers can be greatly reduced. In addition, the backdoor access path can be quickly obtained during the register configuration process, thereby improving the register configuration efficiency.
