Description

Technical Field

[0001] The present invention relates to the technical field of chip verification, and particularly relates to a register configuration method, apparatus, device 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. To achieve higher integration, the number of instantiations of the same circuit module in the chip increases geometrically. To save bus address resources and adapt to various usage scenarios, a design method in which a set of register address segments is shared by registers in the instantiated multiple circuit modules, and a broadcast access method and a gated module access method coexist has become an important means for the chip 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, meeting the design specifications and functional requirements.

[0004] In traditional register verification methods, generally, a pre-generated register model is used to maintain the register information in each circuit module. However, since the register lists of the instantiated multiple circuit modules are the same, and only one register's attribute value can be stored at one address in the register model, the traditional register model can only be used for the register verification work of non-instantiated multiple circuit modules and cannot be used for the register verification work of instantiated multiple circuit modules. In the prior art, if it is necessary to verify the registers in the instantiated multiple circuit modules with the broadcast access method, it is necessary to establish a special test case to test the functions related to the broadcast access, which reduces the real-time performance and coverage of the verification. In the case of a large number of circuit module instantiations or a large number of registers, the register attribute array will also increase geometrically, which also increases the challenge of maintaining the verification platform. Summary of the Invention

[0034] Embodiment I

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

[0036] S110. Through the register control module, when it is determined that the obtained register operation instruction is a front-door issued register configuration transaction, send the register operation instruction to the register model, and obtain the register information of the register to be configured returned by the register model.

[0037] Optionally, Figure 2 The structural schematic diagram of a chip verification platform provided by an embodiment of the present invention. As Figure 2 shown, the chip verification platform includes a register control module, a register comparison module, a register model, an additional register model, and a system under test.

[0038] Optionally, the system under test may refer to the chip to be verified. The system under test includes multiple circuit modules. The circuit modules can be un-instantiated 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 segment, it will greatly occupy the address space of the control bus and affect the address allocation. Therefore, in 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. Therefore, only the data of one register is stored at one address in the register model.

[0040] Figure 3 The structural schematic diagram of an existing chip verification platform. As Figure 3As shown in the figure, in the existing chip verification platform, it only includes a register model, a register processing module, and a system under test. When configuring registers according to the existing chip verification platform, the register model cannot maintain all the register attributes of multiple instantiated circuit modules. Therefore, in the prior art, test cases are generally established, and an attribute array of multiple instantiated circuit modules is established in the test cases to save the attribute values of multiple instantiated circuit modules. However, through the method of test cases, it is impossible to monitor any register access in real time like the register model, which reduces the real-time performance and coverage rate of verification. If the number of circuit module instantiations or the number of registers is large, the register attribute array will increase geometrically, with a high complexity, and the challenge of maintaining the verification platform will also increase.

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

[0042] In an optional example, when circuit module B is instantiated into circuit modules B1, B2, ……, Bn, if circuit module B1 includes register 1, register 2, and register 3, then circuit modules B2, ……, 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 only one register's attribute value can be saved at one address in the register model and it can only be used for the register verification work of circuit modules that are not instantiated multiple times, the present invention proposes to add an additional register model to the chip verification platform to maintain the register information of circuit modules instantiated multiple times through the additional register model.

[0044] Optionally, the front-door issued register configuration transaction can refer to issuing the register configuration transaction to the system under test through a standardized method such as an interface or a communication channel.

[0045] Optionally, in the register model proposed by the present invention, the register model can maintain the register information and attribute values of the un-instantiated multiple circuit modules. At the same time, the register model also includes the register information of the instantiated multiple circuit modules. The register information can be information such as address, name, the circuit module to which it belongs, and whether the circuit module to which it belongs is an instantiated multiple circuit module. However, the register model does not maintain the register attributes of the instantiated multiple circuit modules. The additional register model is not restricted by the address. The additional register model can maintain the register attributes of the instantiated multiple circuit modules, and the registers in the instantiated multiple circuit modules are all identified by the register name. For example, the additional register can maintain the circuit module B2, the register x, and the 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 for the register to be configured, so as to replace the original attribute value of the register to be configured in the chip according to the attribute value in the register operation instruction.

[0047] Optionally, after the register control module receives the register operation instruction, it sends the register operation instruction to the register model, so that the register model can obtain 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 return 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, the 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 the instantiated multiple circuit modules, the returned register information of the register to be configured may also include the selection module information in the circuit module to which the register to be configured belongs.

[0049] S120. Through the register control module, generate a register configuration transaction according to the register information and the register operation instruction, and send the register configuration transaction to the system under test for the system under test to 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, it can determine the target attribute value of each attribute to be configured for the register to be configured according to the register operation instruction, combine the register address and the target attribute value to generate a register configuration transaction, and send the register configuration transaction to the system under test for the system under test to 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 circuit modules instantiated multiple times, a selection module may be included, which can be used to configure the circuit module as a broadcast access mode or a gated module mode.

[0052] Optionally, if the circuit module is configured in broadcast access mode, one address can correspond to registers with the same name in each instantiated multiple circuit modules. For example, when the circuit module B is not instantiated multiple times, the address adress_0 can correspond to the register x in the circuit module B. When the circuit module B is instantiated as circuit modules B1, B2,..., Bn, the address adress_0 can correspond to the register x in each of the circuit modules B1, B2,..., Bn.

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

[0054] Furthermore, if in the register configuration transaction received by the system under test, the register to be configured belongs to a circuit module not instantiated multiple times, it can be directly configured according to the register address and the target attribute value of the register to be configured; if the register to be configured belongs to a circuit module instantiated multiple times and the circuit module is configured in broadcast access mode, each register belonging to the register address is configured according to the target attribute value; if the register to be configured belongs to a circuit module instantiated multiple times and the circuit module is configured in broadcast access mode, the register specified for the register address in the selection module is configured according to the target attribute value.

[0055] S130. Through the register control module, update 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.

[0056] Optionally, in order to verify the reliability and accuracy of the register configuration, it is necessary to maintain the attribute values of the register 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 so, at least one register is determined in the additional register model, and the attributes of the register determined in the additional register model are updated with the target attribute value.

[0058] Further, if the register to be configured belongs to the instantiated multiple circuit modules, the information of the circuit module to which the register to be configured belongs is used to determine whether the circuit module to which the register to be configured belongs is in the broadcast access mode or the strobe module mode. If it is in the broadcast access mode, all the instantiated circuit module names of the circuit module to which it belongs and the name of the register to be configured are determined, and all the registers in the additional register model that match the instantiated circuit module name and the name of the register to be configured are updated to the target attribute value; if it is in the strobe module mode, the target instantiated circuit module corresponding to the strobe module mode needs to be obtained, and the register in the target instantiated circuit module in the additional register model that corresponds to the name of the register to be configured is updated to the target attribute value.

[0059] S140. Through the register comparison module, when it is monitored that the register configuration operation is performed on the system under test, attribute comparison is performed according to the interface information, register model, and additional register model of the system under test.

[0060] Optionally, through the register comparison module, the register configuration operation on the interface of the system under test can be monitored in real time. 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 the register configuration operation is monitored, the interface information can be parsed to obtain the register attributes and register address of the currently configured register in the system under test, and the register address is sent to the register model again to obtain the register information fed back by the register model to the register comparison module.

[0062] Further, after obtaining the register information, it is first necessary to determine whether it belongs to the register of the instantiated multiple circuit modules. If it belongs to the register of the instantiated multiple circuit modules, the state of the selection register is read later to determine whether it is in the broadcast access mode or the strobe module access mode, and then the attribute values of the corresponding register are obtained from the additional register model and compared with the monitored register configuration to complete the closed-loop inspection work of the register. If it belongs to the register of the non-instantiated multiple circuit modules, 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, through the register control module, when it is determined that a register configuration transaction is obtained from the front door, sends the register operation instruction to the register model, and obtains the register information. Through the register control module, a register configuration transaction is generated and sent to the system under test. Through the register control module, the attributes of the register to be configured are updated in the register model or the additional register model. Through the register comparison module, when it monitors that the system under test performs a register configuration operation, according to the interface information of the system under test, the register model, and the additional register model, the method of attribute comparison does not affect the existing test platform's use of registers, is compatible with the original register access method, has portability and popularity, 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, improving the accuracy and speed of register verification, and effectively solving the problem of verifying the coexistence of a set of register models and register address segments, broadcast access mode and gated module access mode for registers in multiple instantiated circuit modules in chip verification.

[0064] Embodiment 2

[0065] Figure 5 The flowchart of a register configuration method for a register configuration transaction sent from the front door provided by the second embodiment of the present invention. Based on the above embodiments, this embodiment specifically describes the register configuration method for a register configuration transaction sent from the front door. As Figure 5 shown, the method includes:

[0066] S210. Through the register control module, when it is determined that the obtained register operation instruction is a register configuration transaction sent from the front door, send the register operation instruction to the register model, and obtain the register information of the register to be configured returned by the register model.

[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 further 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 with multiple instantiations.

[0069] S220. Through the register control module, determine the target attribute values of each attribute of the register to be configured according to the register operation instruction, and generate a register configuration transaction according to the register address of the register to be configured and the target attribute values of each attribute.

[0070] S230. Through the register control module, send the register configuration transaction to the system under test for the system under test to configure the attributes of the register to be configured.

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

[0072] S240. Through the register control module, update 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.

[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 each register of the instantiated multiple circuit modules, and there is no need to manually create an array to maintain.

[0074] The advantage of this setting is that it breaks through the address limitation of the register model, and at the same time increases the portability and maintainability of the verification platform. If there is a modification to the register or the circuit module, only the additional register list needs to be modified to complete the update of the additional register model.

[0075] Among them, through the register control module, 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 may include any of the following:

[0076] 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 circuit module that is not instantiated multiple times, locate the first register to be configured in the register model according to the first register name or register address, and update each attribute array of the first register to be configured with 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 circuit module that is instantiated multiple times, update the attributes of the register to be configured in the additional register model according to the register information and the register operation instruction.

[0078] Optionally, the register model maintains the attributes of multiple un-instantiated circuit modules. The register model stores the names, addresses, names of the circuit modules to which the registers belong, whether the circuit modules to which the registers belong are instantiated circuit modules, and the register attribute arrays. After determining the address or name of the registers of multiple un-instantiated 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 the module name of the circuit module to which the register belongs and the register name. For example, register x of circuit module B2. Such a 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 multiple un-instantiated circuit modules, the first register to be configured can be directly located in the register model according to the first register name or the register address.

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

[0082] Through the register control module, when it is determined according to the first circuit module information that the register to be configured belongs to multiple instantiated circuit modules, the register configuration method of the first circuit module is determined to be the broadcast access method or the strobe module method according to the first selection module information;

[0083] Through the register control module, if the register configuration method is the broadcast access method, multiple second registers to be configured are located in the additional register model according to the first register name, and the attribute arrays of each second register to be configured are respectively updated with the target attribute value; among them, 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 method is the strobe module method, 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 with the target attribute value.

[0085] Optionally, the register model also maintains the addresses, names, names of the circuit modules to which the registers belong, whether the circuit module is an instantiated circuit module, and the register configuration method as a broadcast access method or a gated module method. If it is a gated module method, 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 multiple circuit modules are instantiated, one register address corresponds to the registers with the same name in each of the multiple instantiated circuit modules. The first register name can include the specified registers in each of the multiple instantiated circuit modules. For example, it can be register x of circuit module B1, register x of circuit module B2,..., register x of circuit module Bn.

[0087] Optionally, if it is a broadcast access method, all the registers in the additional register model that belong to the first register name are determined as the second registers to be configured.

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

[0089] S250. Through the register comparison module, when it monitors that the system under test performs a register configuration operation, it parses the interface information of the system under test, obtains the target address of the currently configured register in the system under test and the first attribute value of each attribute of the currently configured register, and sends the target address to the register model to obtain the register information of the currently configured register returned by the register model.

[0090] Optionally, the first attribute value can refer to the attribute value obtained by parsing the interface information, and the target address can refer to the address of the currently configured register in the system under test. After sending the target address to the register model, the register information of the currently configured register feedback by the register model can be obtained, which can include the name, address, name of the circuit module to which the register belongs, whether the circuit module is a multiple instantiated circuit module. If it is a multiple instantiated circuit module, the register information of the currently configured register also includes the register configuration method as a broadcast access method or a gated module method. If it is a gated module method, it also includes the module name specified by the gated module.

[0091] S260. Through the register comparison module, perform 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.

[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 the un-instantiated multiple circuit modules, the register information of the current configuration register further 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 through the register comparison module according to the register information of the current configuration register and the first attribute value may include any of the following:

[0094] Through the register comparison module, when it is determined according to the second circuit module information that the current configuration register belongs to the un-instantiated multiple circuit modules, compare the first attribute value with the second attribute value to obtain the comparison result of the register configuration;

[0095] Through the register comparison module, when it is determined according to the second circuit module information that the current configuration register belongs to the instantiated multiple circuit modules, perform attribute comparison with the additional register model according to the register information of the current configuration register and the first attribute value.

[0096] Optionally, if the currently configured register belongs to the un-instantiated multiple circuit modules, the second attribute value of the register can be directly obtained in the register model, and 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 configured value of the register in the register model is the same as that in the system under test, and the closed-loop check of the register configuration is completed.

[0104] Embodiment III

[0105] Figure 6The figure is a flowchart of a register configuration method when accessing a register through a backdoor according to Embodiment 3 of the present invention. Based on the above embodiments, this embodiment specifically describes the register configuration method when accessing a register through a backdoor. As Figure 6 shown, the method includes:

[0106] S310. Through the register control module, when it is determined that the obtained register operation instruction is a backdoor access to a register, send the register operation instruction to the register model, and obtain the second register name of the register to be configured returned by the register model.

[0107] Optionally, accessing a register through a backdoor may refer to directly obtaining the backdoor access address of the register, so as to configure the attribute value of the register directly through the backdoor access address of the register without modifying the register configuration through an interface.

[0108] Optionally, since there is only one register bank in the register model, only one register bank can be accessed when implementing backdoor access, and backdoor access cannot be performed on other register banks. The backdoor access path is of string type. If backdoor access is to be implemented, then multiple instantiated circuit modules need to be saved, such as circuit modules B1, B2,..., Bn, circuit modules C1, C2,..., Cm, circuit modules D1, D2,..., Dp. The backdoor access paths of all registers of these circuit modules need to be saved. In an existing chip, the number of instantiated circuit modules and registers actually set is relatively large. If the backdoor access paths are saved manually, the workload is extremely large, and multiple-level selection and judgment are required, which is not conducive to the maintenance of the verification platform.

[0109] In the embodiment of the present invention, an additional register model can provide the backdoor access paths of the registers corresponding to each instantiated circuit module. 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 can be directly obtained from the additional register model, and the backdoor access operation is completed by calling the backdoor access function built in the UVM (Universal Verification Methodology) function library. The introduction of the additional register model solves the problem of the backdoor access path.

[0110] It can be understood that if the method of saving the backdoor access path in the prior art is adopted, 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 the problem that the backdoor access paths of the registers in each instantiated multiple circuit modules cannot be saved in the existing register model is solved, but also the backdoor access path corresponding to the name can be quickly obtained after inputting the second register name.

[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. Through the register control module, obtain the backdoor access address corresponding to the second register name in the additional register model, and determine the second attribute values of the attributes of the register to be configured according to the register operation instruction.

[0113] S330. Through the register control module, call the backdoor access function, and configure the attributes of the register to be configured in the system under test according to the backdoor access address and the second attribute values.

[0114] Optionally, the backdoor access function can be the built-in backdoor access function in the UVM function library.

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

[0116] The technical solution of the embodiment of the present invention, by using the register control module, when it is determined that the obtained 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. The backdoor access address corresponding to the second register name is obtained in the additional register model, and the second attribute values of the attributes of the register to be configured are determined according to the register operation instruction. The backdoor access function is called, and the attributes of the register to be configured in the system under test are configured according to the backdoor access address and the second attribute values. In this way, the backdoor access paths of the registers in the instantiated multiple circuit modules can be quickly obtained through the additional register model. For a chip with a large number of registers, the workload of chip designers can be greatly reduced. Moreover, during the register configuration process, the backdoor access path can be quickly obtained, improving the register configuration efficiency.
