Description

Technical Field

[0001] The present invention relates to the technical field of integrated circuit verification, and particularly to a verification method, device, medium and equipment based on low-power design. Background Art

[0002] With the rapid development of technology, remarkable progress has been made in fields such as artificial intelligence, 5G communication, big data centers, and automotive electronics. The rapid development of these fields has made low-power design no longer limited to portable electronic devices, but has become a key requirement for more terminal products. These terminal products have increasingly high requirements for chip performance. Although the development of chip manufacturing processes has promoted the continuous improvement of transistor integration and enhanced chip performance, it has also led to more severe chip heat dissipation problems. Therefore, low-power design is particularly important in the current electronics industry.

[0003] Currently, low-power design is mainly achieved through technologies such as dynamic voltage and frequency scaling (DVFS), clock gating, and power gating. No matter which technology is used for low-power design, verification is required to verify whether the low-power design affects the normal function of the chip, whether the power consumption index meets the standard, and whether the switching of the chip in different power consumption modes is normal.

[0004] Existing verification methods for low-power design usually adopt directed testing, that is, testing a specific function mode under a certain low-power mode. Although this method can verify some functions, its verification is single and the reusability is poor, making it difficult to be reused in different design scenarios or functional modules. Therefore, a verification method for low-power design that can meet diverse verification requirements is needed. Summary of the Invention

[0054] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

[0055] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will describe in detail the specific implementation manners, structures, features, and their effects of the application according to the present invention with reference to the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0056] Aiming at the problem that the functional verification of the current verification method for low-power design is single, the reusability is poor, and it is difficult to be reused in different design scenarios or functional modules, the embodiment of the present application provides a verification method based on low-power design, as Figure 1 shown, this method includes:

[0057] 102: Obtain the data to be verified and multiple target interface types of the analog device to be verified in multiple low-power modes;

[0058] 104: Based on each low-power mode and each target interface type, generate configuration information, perform encapsulation processing on the data to be verified and the configuration information, obtain the encapsulated data corresponding to each target interface type, and send the encapsulated data to the analog device to be verified, so that the analog device to be verified performs low-power simulation operation according to the encapsulated data and outputs the actual operation result corresponding to the target interface type;

[0059] 106: Predict the low-power operation result of the analog device to be verified based on the encapsulated data to obtain a prediction result;

[0060] 108: Compare the actual operation result and the prediction result, and determine the verification result of each low-power mode according to the comparison result.

[0061] Specifically, the main body of the verification method based on low-power design is the verification platform, such as the verification platform built based on Synopsys VCS software, the verification platform built based on Cadence Incisive software, etc. The simulation device to be verified is a simulation device through software simulation. There are many types of low-power modes. From the perspective of electronic devices, they include standby mode, sleep mode, flight mode, etc. From the perspective of integrated circuits, they include gated clock mode, power gating mode, dynamic voltage and frequency adjustment mode, etc. When performing low-power design verification, different low-power modes are set, and verification is carried out under different low-power modes. Each low-power mode corresponds to matching configuration information and data to be verified.

[0062] Generally, multiple interfaces are set on the simulation device to be verified, such as SPI interface, UART interface, etc. In some low-power modes, the functions of these interfaces are among the functions to be verified. Therefore, it is necessary to set the interface information corresponding to these interfaces in different low-power modes. According to the data protocols of the interface types, the interface configuration information, mode configuration information, and data to be verified in different low-power modes are combined in a preset order, and then the combined data is encapsulated to obtain the encapsulated data corresponding to the target interface type. The encapsulated data is sent to the simulation device to be verified. After receiving the encapsulated data, the simulation device to be verified parses the encapsulated data, then configures according to the parsed data, performs an operation according to the data to be verified after the configuration is completed, and finally outputs the actual operation result after the operation is completed to the verification platform.

[0063] The verification platform makes a low-power verification prediction of the simulation device to be verified based on the encapsulated data, obtains a prediction result, compares the prediction result with the actual operation result of the simulation device to be verified, and determines whether the verification is qualified according to the comparison result.

[0064] This application provides a verification method based on low-power design. Compared with the prior art, it obtains the data to be verified and the target interface type in each low-power mode, generates configuration information based on the low-power mode and the target interface type, encapsulates the data to be verified and the configuration information in multiple low-power modes according to the target interface type to obtain the encapsulated data corresponding to each target interface type, sends the encapsulated data to the simulation device to be verified, obtains the actual operation result of the simulation device to be verified running according to the encapsulated data, makes a prediction of the low-power operation result of the simulation device to be verified, compares the actual operation result and the prediction result, and verifies the legality of the low-power design according to the comparison result. It can verify multiple low-power modes of multiple different interface types, not only realizing the simultaneous verification of multiple functions, but also meeting the requirement of strong reusability, and improving the verification efficiency of low-power design.

[0065] In an embodiment of the present invention, for further limitation and illustration, as Figure 2As shown, based on each low-power mode and each target interface type, configuration information is generated, and the data to be verified and the configuration information are encapsulated to obtain the encapsulated data corresponding to each target interface type, including:

[0066] 202: Configure the information of the analog device to be verified in each low-power mode according to the low-power mode of the analog device to be verified to obtain mode configuration information;

[0067] 204: Configure the target interface of the analog device to be verified according to each target interface type of the analog device to be verified to obtain interface configuration information;

[0068] 206: For each target interface type, combine the mode configuration information in each low-power mode and the data to be verified to obtain the combined data to be verified in each low-power mode;

[0069] 208: Package and process the interface configuration information and the combined data to be verified in multiple low-power modes in the preset low-power mode verification order to obtain the encapsulated data corresponding to each target interface type.

[0070] In this embodiment, there are multiple low-power modes usually to be verified, and the configuration information of each low-power mode is different. Therefore, according to different low-power modes, the mode configuration information corresponding to this low-power mode is generated. At the same time, the data to be verified corresponding to the function to be verified in each low-power mode is also different. Therefore, the mode configuration information and the data to be verified in each low-power mode are generated, and the mode configuration information and the data to be verified in each low-power mode are combined together to obtain the combined data to be verified in each low-power model.

[0071] Taking the target interface type including the SPI interface type and the APB interface type as an example, if the interface data type is the SPI data type, configure the SPI interface type to obtain the SPI interface configuration information. Based on the SPI interface protocol, package and process the interface configuration information and the combined data to be verified in multiple low-power modes in the preset low-power mode verification order to obtain the encapsulated data corresponding to the SPI interface type; if the interface data type is the APB data type, configure the APB interface type to obtain the APB interface configuration information. Based on the APB interface protocol, package and process the interface configuration information and the combined data to be verified in multiple low-power modes in the preset low-power mode verification order to obtain the encapsulated data corresponding to the APB interface type.

[0072] Correspondingly, the simulation device to be verified receives the encapsulated data through the interface, parses the encapsulated data, and based on the parsed data, identifies the interface setting information, mode configuration information, and data to be verified. It sets the interface according to the interface configuration information, sets the low-power mode according to the mode configuration information, and executes the function to be verified based on the data to be verified.

[0073] In one embodiment, the actual operation result and the predicted result are compared, and based on the comparison result, the verification result of each low-power mode is determined, including:

[0074] If the actual operation result is exactly the same as the predicted result, the low-power design passes the verification; if the actual operation result is not exactly the same as the predicted result, the low-power design fails the verification.

[0075] Specifically, if the configured target interface type is the SPI interface, the actual operation data is collected and compared with the predicted result obtained by prediction under the encapsulated data corresponding to the SPI target interface; if the configured target interface type is the APB interface, the actual operation data is collected and compared with the predicted result obtained by prediction under the encapsulated data corresponding to the APB target interface. If the actual operation result is exactly the same as the predicted result, the low-power design passes the verification, and the configuration and functions of the low-power mode all pass the inspection. If the actual operation result is not exactly the same as the predicted result, the low-power design fails the verification, the difference between the actual operation result and the predicted result is obtained, and based on the difference, verification modification information is generated and sent to the simulation device to be verified.

[0076] In one embodiment, the target interface type includes at least one of the SPI interface type, I 2 C interface type, UART interface type, APB interface type, AHB interface type, AXI interface type, and ASB interface type.

[0077] Specifically, many interface types are set on the device to be verified, and data communication is carried out with other devices, platforms, or servers through these interfaces. The corresponding target interface type is selected according to the verification requirements, the interface data is configured according to the selected target interface type, and then the interface configuration information, the data to be verified, and the configuration information under each low-power mode are encapsulated together to obtain the encapsulated data corresponding to the target interface type.

[0078] In one embodiment, the main body of the verification method based on low-power design is a verification platform, such as a verification platform built based on Synopsys VCS software, a verification platform built based on Cadence Incisive software, etc. The simulation device to be verified is a simulation device through software simulation. There are many components on the verification platform, and these components process data. Taking the verification of low-power design for the SPI interface as an example, the complete process is as follows:

[0079] First, the init_sequence (a sequence component) generates initialization information about the SPI interface, that is, interface configuration information. The DUT (abbreviation for Device Under Test, which is the simulation device to be verified in this application) completes the initialization operation according to the interface configuration information and selects the SPI interface.

[0080] Second, the pmu_sequence (a sequence component) signal is randomly generated through the pmu_transaction structure at the top level (pmu_transaction represents a transaction for interacting with the power management unit, containing various information related to power management and used to describe an operation on the power management unit). The DUT is configured through the pmu_sequence signal to turn on the low-power mode configuration switch, configure the corresponding mode switching register, and wait for the operation to complete. The pmu_sequence signal is also mode configuration information.

[0081] Third, the spi_sequence (a sequence component) signal is generated based on the spi_transaction (a transaction class object that represents a transaction for interacting with the SPI interface) structure. After detecting the generation of the above two-step configuration information, the corresponding register part configured through the interface is sent to the spi_driver (a component). The spi_driver obtains the data to be verified of the DUT, encapsulates the configuration information and the data to be verified to obtain encapsulated data, and transmits the encapsulated data to the SPI interface of the DUT.

[0082] In the fourth step, spi_monitor (a component) respectively detects the information transmitted by the output interface of the DUT and the information sent by the spi_driver to the DUT, and transmits the information transmitted by the output interface of the DUT and the information sent by the spi_driver to the DUT to the pmu_model (Power Management Unit reference model, a component in the verification environment). The pmu_model will simulate the low-power operation of the DUT based on the information sent by the spi_driver to the DUT, predict the information of the DUT output interface, that is, the prediction result, and the information transmitted by the output interface of the DUT is the actual operation result.

[0083] In the fifth step, the pmu_model sends the prediction result and the actual operation result to the scoreboard (a verification component), and the scoreboard performs unified post-processing on the prediction result and the actually collected operation result and then conducts comparative analysis on the data.

[0084] In the sixth step, based on the data comparison information and the information of the system operation, it is finally obtained whether the verification of the low-power mode of the DUT passes.

[0085] In one embodiment, the complete process of verifying the low-power design through the APB interface is as follows:

[0086] First, in the init_sequence, initialization information about the APB interface, that is, interface configuration information, is generated. The DUT completes the initialization operation according to the interface configuration information and selects the APB interface.

[0087] In the second step, the pmu_sequence signal is randomly generated through the top-level pmu_transaction structure, and the DUT is configured through the pmu_sequence signal so that the DUT is configured to turn on the low-power mode configuration switch and configure the corresponding mode switching register. The pmu_sequence signal is also mode configuration information.

[0088] In the third step, the apb_sequence is generated based on the apb_transaction structure. After detecting the generation of the above two-step configuration information, the corresponding register part configured through the interface is sent to the apb_driver. The spi_driver obtains the data to be verified of the DUT, encapsulates the configuration information and the data to be verified to obtain the encapsulated data, and transmits the encapsulated data to the APB interface of the DUT.

[0089] Step 4: The apb_monitor respectively detects the information transmitted by the output interface of the DUT and the information sent by the apb_driver to the DUT, and transmits the information transmitted by the output interface of the DUT and the information sent by the spi_driver to the DUT to the pmu_model. The pmu_model will simulate the low-power operation of the DUT based on the information sent by the spi_driver to the DUT, predict the information of the DUT output interface, that is, the prediction result, and the information transmitted by the output interface of the DUT is the actual operation result.

[0090] Step 5: The pmu_model sends the prediction result and the actual operation result to the scoreboard, and the scoreboard performs unified post-processing on the prediction result and the actually collected operation result and then conducts comparative analysis on the data.

[0091] Step 6: According to the data comparison information and the information of the system operation, it is finally obtained whether the verification of the low-power mode of the DUT is passed.

[0092] The above operations for the SPI and APB interfaces are all a complete transmission. Multiple different low-power modes can be respectively configured for switching, different register configurations can be used, and repeated tests can be carried out. At the same time, different low-power scenarios can also be simulated to test the extreme operations or abnormal operations of the DUT.

[0093] Since there are many modes and boundary conditions in the low-power design, randomization and repeated iteration can be carried out multiple times to verify all boundary conditions. Appropriate targeted test cases can be supplemented to ensure complete verification. The power consumption environment in different scenarios can also be simulated by changing the data information of the config for exception handling of the environment, so as to verify the stability of the DUT. When building the platform, the DUT is defaulted to a black box for operation, reducing the dependence on the DUT. Therefore, the verification method based on low-power design provided by this application has better portability.

[0094] Further, as an implementation of the above Figure 1 shown method, an embodiment of the present invention provides a verification device based on low-power design, as Figure 3 shown, the device includes:

[0095] An acquisition module 302, configured to acquire the data to be verified and multiple target interface types of the simulation device to be verified in multiple low-power modes;

[0096] The encapsulation module 304 is used to generate configuration information based on each low-power mode and each target interface type, perform encapsulation processing on the data to be verified and the configuration information, obtain the encapsulated data corresponding to each target interface type, and send the encapsulated data to the simulation device to be verified, so that the simulation device to be verified performs low-power simulation operation according to the encapsulated data and outputs the actual operation result corresponding to the target interface type;

[0097] The prediction module 306 is used to predict the low-power operation result of the simulation device to be verified based on the encapsulated data, and obtain the prediction result;

[0098] The comparison module 308 is used to compare the actual operation result and the prediction result, and determine the verification result of each low-power mode according to the comparison result.

[0099] This application provides a verification device based on low-power design. Compared with the prior art, it obtains the data to be verified and the target interface type under each low-power mode, generates configuration information based on the low-power mode and the target interface type, encapsulates the data to be verified and the configuration information under multiple low-power modes according to the target interface type to obtain the encapsulated data corresponding to each target interface type, sends the encapsulated data to the simulation device to be verified, obtains the actual operation result of the simulation device to be verified running according to the encapsulated data, predicts the low-power operation result of the simulation device to be verified, compares the actual operation result and the prediction result, and verifies the legality of the low-power design according to the comparison result. It can verify multiple low-power modes of multiple different interface types, not only realize the simultaneous verification of multiple functions, but also meet the requirement of strong reusability, and improve the verification efficiency of the low-power design.
