Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

Example 1

FIG. 1 is a flowchart of a test stimulus multi-platform multiplexing method in Embodiment 1 of the present invention. This embodiment can be applied to the case of testing multiple tested objects with similar test stimuli. Similar test stimuli include multiple tested objects. The same test stimuli and different test stimuli between the test objects. The method may be performed by a test excitation multi-platform multiplexing apparatus, which may be implemented by hardware and/or software, and may generally be integrated in equipment providing test services. As shown in Figure 1, the method includes:

Step 110: Obtain a general test stimulus file corresponding to a plurality of tested objects, and a macro definition file corresponding to each tested object; the general test stimulus file is used to describe the same test stimulus among the tested objects, and the macro definition file uses It is used to describe the different test stimuli among the test objects.

In this embodiment, the object under test is also called a device under test (Design Under Test, DUT), which can be tested and verified on a verification platform based on Universal Verification Methodology (UVM). The properties of the multiple tested objects in this embodiment are similar and the driving interfaces are similar. Exemplarily, the characteristics are similar means that each of the multiple tested objects has a certain access depth and/or access width, but the access depth and/or access width are different in numerical value. Driver interface similarity means that multiple DUTs can be driven by similar test stimuli of the same main process.

Since multiple tested objects have similar characteristics and similar drive interfaces, the test stimulus of the same main process needs to be tested, but the test stimulus is not exactly the same, but has both the same part and different parts. The test incentives are similar. Exemplarily, the same test stimuli include: the same main process, and sub-processes and/or parameters; different test stimuli include: sub-processes and/or parameters.

In this embodiment, descriptions of the same test stimuli among the tested objects are written in a general test stimulus file in advance; and descriptions of different test stimuli among the tested objects are written into a macro definition file in advance. Among them, the general test stimulus file refers to the description of the test task for an object under test, and its content may include test objectives, test scenarios, input data, test steps, expected test results, etc., to test whether the object under test meets certain requirements. a set requirement. The macro definition file uses the macro definition method to abstractly describe different test stimuli, so that macros are used to replace different parameters or different sub-processes between the tested objects. Moreover, the macro definition file integrates the abstract descriptions of different test stimuli in various aspects, such as different characteristics and different time intervals, so as to integrate the abstract stimuli descriptions that are similar in many aspects into one file for easy maintenance.

Further, if the test stimuli of the multiple tested objects include at least two types of test stimuli, wherein, the test stimuli belonging to the same type can be considered to be similar, then the present embodiment can be based on whether the test stimuli have the same main process. , divide the similarity of multiple tested objects in advance, treat the tested objects with the same main process as similar tested objects, and divide them into the same set of similar objects, aiming at similar tested objects in the same set , write a general test stimulus file corresponding to a plurality of similar test objects, and a plurality of macro definition files corresponding to each similar test object respectively, for testing each similar test object. In this embodiment, for each tested object, a general test stimulus file corresponding to the similar object set to which the tested object belongs and a macro definition file corresponding to the tested object are acquired. It can be seen that each similar test object obtains the same general test stimulus file and different macro definition files.

Step 120: Use the general test stimulus file and the macro definition file to drive the corresponding tested objects respectively, so as to test each tested object under the comprehensive test stimulus; the comprehensive test stimulus includes the same test stimulus between each tested object and each tested object. Different test stimuli between the test object and other test objects.

After obtaining the general test stimulus files corresponding to multiple measured objects and the macro definition files corresponding to each measured object, drive the general test stimulus files to the interfaces of each measured object, and drive the macro definition files to the corresponding measured objects. interface, and then drive the corresponding tested objects to use two files for testing on the verification platform. In the test process, it is necessary to execute the main process in the general test file, and call the macro definitions of different subprocesses and/or parameters in the macro definition file to obtain a complete comprehensive test stimulus, and then test each object under test under the comprehensive test stimulus. .

In a specific embodiment, the general test stimulus file and the macro definition file are first loaded into the compilation environment of each corresponding tested object; in the compilation environment, the general test stimulus file and the macro definition file are compiled to generate object code. Specifically, in the general test stimulus file, the different test stimuli of each tested object are represented by the macro name (that is, the macro definition). For the convenience of description and distinction, the same macro name of each tested object is called the general macro name; The definition file includes a general macro name and a character string expanded from the general macro name, and different test stimuli are represented by the character string expanded from the general macro name. Based on this, in the compilation environment, when compiling to the general macro name in the general test stimulus file, the string expanded from the general macro name in the macro definition file is called to replace the general macro name in the general test stimulus file, and generate object code.

Next, execute the target code to generate a comprehensive test stimulus; test each tested object under the comprehensive test stimulus to obtain the test result of each tested object; compare the test result of each tested object with the corresponding expected test result Compare and get test conclusions. Among them, the expected test result is stored in the general test stimulus file, which is used to describe the desired output or index of the tested object, for example, the system response time is 2ms.

In the embodiment of the present invention, the general test stimulus file is used to describe the same test stimulus among the tested objects, and the general test stimulus file is used to drive the tested objects, thereby realizing the reuse of the same general test among different test objects Stimulus file, which realizes the multiplexing of test stimuli; the macro definition file is used to describe the different test stimuli between the tested objects, and the general test stimulus file and the macro definition file are used to drive the corresponding tested objects respectively, so as to synthesize the different test stimuli. Test each tested object under test stimulus, without having to write a complete set of test stimulus for each tested object, using the same top-level stimulus description and different bottom-level drivers to achieve the same test stimulus, and between different test objects. Multiplexing, reducing the amount of coding and coding time, improving coding efficiency, and almost no repetitive description, which is convenient for the maintenance of test incentives; moreover, different test incentives are abstractly described through macro definitions, integrating similar abstractions in many aspects. The incentive description makes the test incentive description more concise and convenient, and facilitates human-computer interaction, further improves the coding efficiency, and is conducive to efficiently completing the test work.

Embodiment 2

On the basis of the above embodiments, this embodiment describes in detail the description of the macro definition file, and the process of generating object code by compiling the general test stimulus file and the macro definition file under different descriptions. The macro definition file includes at least one of the following descriptions. The following describes each description and the corresponding object code generation process in detail.

The first case: the macro definition file includes: a general macro name that defines the test stimulus, and a character string that is expanded from the general macro name and defines the test stimulus of the tested object. Correspondingly, in the compilation environment, when compiling into the general macro name of the test stimulus in the general test stimulus file, the test stimulus that defines the object under test, which is expanded from the general macro name in the macro definition file, is called. , replace the general macro name of the test stimulus in the general test stimulus file, and generate the target code.

In this case, the generic macro name that defines the test stimulus can be considered the name of the test stimulus. However, the test stimuli of each tested object are not the same, and the names of the test stimuli should be distinguished. Therefore, the character string that defines the test stimuli of the tested object, which is expanded from the general macro name, is used as the test stimuli of the tested object. The name can also be further used as the identifier of the macro definition file. By replacing the general macro name in the general test stimulus file with the string corresponding to each tested object, the target code is generated, and the calling of different macro definition files is realized.

The second case: the macro definition file includes: a general macro name that defines the description sequence, and a character string that defines the description sequence of the measured object extended from the general macro name; wherein, the description sequence is defined by a preset number of basic excitation units according to The set order is obtained and used to describe the different test procedures among the tested objects. Correspondingly, in the compilation environment, when compiling into the general macro name of the description sequence in the general test stimulus file, call the description sequence in the macro definition file that is expanded from the general macro name and defines the object under test. , replace the general macro name describing the sequence in the general test stimulus file, and generate the target code.

In this case, the basic excitation unit can be an operation step, and the description sequence is an operation process obtained by arranging multiple operation steps in a set order. Therefore, the macros that describe the sequence defined in the macro definition file of each measured object have the same macro name, that is, the general macro name; it is specifically described by the character string that is expanded from the general macro name and defines the description sequence of the measured object. Different test flow between each test stimuli, so when the target code is executed to test each tested object, different test flow is realized by calling the macros describing the sequence in different macro definition files.

The third case: the macro definition file includes: the general macro name that defines the time gap, and the character string that expands from the general macro name and defines the time gap of the measured object; wherein, the string of the time gap is used to establish the corresponding The time slot in which the test object is adapted to send the stimulus. Correspondingly, in the compilation environment, when compiling into the general macro name of the time slot in the general test stimulus file, the time slot in the macro definition file that is expanded from the general macro name and defines the measured object is called. , replace the general macro name of the time slot in the general test stimulus file, and generate the target code.

In this case, when testing each measured object, the general stimulus file needs to be divided into multiple data packets and sent to the measured object, and the time gap refers to the time interval for sending adjacent data packets. Since different measured objects have different requirements for time gaps, the macros of the time gaps defined in the macro definition files of each measured object have the same macro name, that is, the general macro name. The string of the time gap of the tested object describes the different time intervals for sending adjacent data packets, so that when the target code is executed to test each tested object, the time gap in the file is defined by calling different macros. String, setting different time intervals for sending adjacent packets.

The fourth case: the macro definition file includes: a general macro name that defines the initialization process, and a string that is expanded from the general macro name and defines the initialization process of the object under test, wherein the initialization process is used to initialize the object under test. The configuration process for the object. Correspondingly, in the compilation environment, when compiling into the general macro name of the initialization process in the general test stimulus file, the initialization process that defines the object under test, which is expanded from the general macro name in the macro definition file, is called. character string, replace the general macro name of the initialization process in the general test incentive file, and generate target code;

In this case, since the initialization configuration process of different objects under test is different, the macros of the initialization process defined in the macro definition file corresponding to each object under test have the same macro name, that is, the general macro name; The string of the macro name that defines the initialization process of the object under test describes the initialization configuration process of different objects under test, so that when the target code is executed to test each object under test, by calling different macro definition files. The string of the initialization process to implement different initialization configuration processes.

The fifth case: the macro definition file includes: a general macro name that defines the characteristics of the object under test, and a character string that is expanded from the general macro name and defines the characteristics of the object under test, wherein the characteristics of the object under test include access depth and/or access width. Correspondingly, in the compilation environment, when compiling into the general macro name of the measured object characteristic in the general test stimulus file, call the macro definition file that is expanded from the general macro name and defines the measured object. Character string, replace the general macro name of the measured object characteristic in the general test stimulus file, and generate target code;

In this case, exemplarily, assuming that the measured object is a memory, and the memory can perform row dimension access or column dimension access, the access width and access depth can be regarded as the number of accessible rows and columns of the memory. Because the characteristics of different measured objects are different, the macros of the measured object characteristics defined in the macro definition file corresponding to each measured object have the same macro name, that is, the general macro name; The character string of the tested object's characteristics of the tested object describes the characteristics of different tested objects, so that when the target code is executed to test each tested object, the test object characteristics in different macro definition files are called. Strings set different properties.

Below, the specific description and testing process of the macro definition file are described in detail with a specific application scenario.

Exemplarily, it is assumed that there are two objects under test, namely the first object under test (Object1) and the second object under test (Object2). The instruction configuration process and logical search process of these two objects under test are similar. Therefore, The same main process can be abstracted from the instruction configuration stimulus and logic search stimulus of the two tested objects, and the corresponding general test stimulus file can be written; then according to the different configuration stimulus and logic search stimulus between the two tested objects Write their own macro definition files. For example, the macro definition file of the object under test Object1 is as follows:

Object1_def.sv:

The macro definition file of the object under test Object2 is as follows:

Object2_def.sv:

In the above two macro definition files, OBJECT_BASE_TEST represents the general macro name of the test stimulus, and the respective test stimulus of the objects under test Object1 and Object2 are extended from TCAM_BASE_TEST, which are strings: Object1_base_test and Object2_base_test, to ensure that the general test stimulus can be used in different Verify that the scene is driven. OBJECT_DIFF_FLOW represents the general macro name that describes the sequence, and describes the different test processes of the objects under test Object1 and Object2. In the general test stimulus, the macro definition sequence with the same name is used for different parts of the process, which can ensure that different descriptions in the test process can be Used in the same generic test stimulus. OBJECT_CFG_2_SEND_TIME represents the general macro name of the same sequence (sequence) or item (item)-driven time gap, where a sequence is a complete information flow, and an item is a collection of the smallest unit in the sequence, because the measured objects Object1 and Object2 The requirements for the time slot for sending the stimulus (ie sequence or item) are different, so in the general test stimulus, macros with the same time slot name are used to establish different time slots to adapt to different measured objects; OBJECT_INIT_FLOW represents the general macro name of the initialization process, OBJECT_WIDTH represents the general macro name of the access width of the tested object, and OBJECT_DEEP represents the general macro name of the access depth of the tested object.

The test equipment obtains the general test stimulus file corresponding to the tested objects Object1 and Object2, the macro definition file Object1_def.sv corresponding to the tested object Object1, and the macro definition file Object2_def.sv corresponding to the tested object Object2, and use the general test stimulus file and macro definition file. The file replaces the test stimulus file corresponding to each tested object in the prior art.

Next, the test equipment loads the general test stimulus file and the macro definition file Object1_def.sv into the compilation environment of the object under test Object1, and loads the general test stimulus file and the macro definition file Object2_def.sv into the compilation environment of the object under test Object2, so as to Compile the general test stimulus file and macro definition file to generate object code.

As shown in Figure 2a, in the prior art, for the objects under test Object1 and Object2, similar test stimuli need to be defined and written in the two test stimuli respectively, which increases the coding time, and once the parameters or sub-processes are modified, It is also difficult to maintain test incentives, which increases the workload of code maintenance. In view of the above problems, as shown in FIG. 2b, the embodiment of the present invention writes a general test stimulus file according to the same test stimulus between two objects under test, and writes the macro definition files Object1_def.sv and Object1_def.sv respectively for the objects Object1 and Object2 under test Object2_def.sv, the two macro definition files use the same macro names to define different sub-processes and parameters in the general test stimulus, so that they can be run in the same general test stimulus file, which facilitates code maintenance , reducing coding time and improving test efficiency.

Then, execute the target code to generate a comprehensive test stimulus; and test the above two tested objects under the comprehensive test stimulus.

Optionally, the test equipment tests each test object according to the set test steps under the comprehensive test incentive, records the test data generated by each test object during the test, and obtains the test result by analyzing the test data. The test results of each tested object are compared with the corresponding expected test results to obtain a test conclusion. Among them, the test conclusion is a summary of the implementation of the test task and the test results, which may include: control measures and results of the test risk, whether the test goal is completed, whether the test is passed, whether there are remaining problems, and whether the next stage can be entered. tests, etc.

Optionally, the test equipment compares the test results of each test object with the corresponding expected test results. If the test results are consistent with the corresponding expected test results, the test target is completed. If all test targets are completed, the test target is completed. The object passes the test; if the test result is inconsistent with the corresponding expected test result, the test target has not been completed, and the tested object has not passed the test.

In this embodiment, the differences in test stimuli are described from the aspects of defining test stimuli, description sequence, time interval, initialization process and the characteristics of the measured object, which cover a wide range and can be applied to a variety of measured objects. In the application scenario; by defining the general macro name and string, and compiling the general test stimulus file and the macro definition file, the target code is generated, and then the above-mentioned different test stimulus is realized by executing the target code.
