Detailed Description
Before describing embodiments of the present disclosure, it should be noted that:
some embodiments of the disclosure are described as process flows, in which the various operational steps of the flows may be numbered sequentially, but may be performed in parallel, concurrently, or simultaneously.
The terms "first," "second," and the like may be used in embodiments of the present disclosure to describe various features, but these features should not be limited by these terms. These terms are only used to distinguish one feature from another.
The term "and/or," "and/or" may be used in embodiments of the present disclosure to include any and all combinations of one or more of the associated features listed.
It will be understood that when two elements are described in a connected or communicating relationship, unless a direct connection or direct communication between the two elements is explicitly stated, connection or communication between the two elements may be understood as direct connection or communication, as well as indirect connection or communication via intermediate elements.
In order to make the technical solutions and advantages of the embodiments of the present disclosure more apparent, the following detailed description of exemplary embodiments of the present disclosure is provided in conjunction with the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments of which are exhaustive. It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other.
In general, a test vector includes a plurality of vector rows. For large SOCs (System on Chip), one test vector may include tens of thousands of vector rows.
In each test, a particular one or more vector rows correspond to a particular pin of the chip, i.e., the ATE device tests the particular pin of the chip by testing the particular one or more vector rows so that the test results of the particular one or more vector rows reflect the performance of the particular pin of the chip. Therefore, there is a need to grasp the test results of the specified vector row of the test vector.
In the prior art, through the digital grabbing function of the ATE equipment, the test results of each appointed row of the test vector can be independently operated so as to grab the test results of the corresponding appointed row. However, the self-contained digital capture function may introduce a number of human operations during execution, including but not limited to: manually marking a designated row in the test vector as "c"; in the test vector needing modification, right clicking to select 'NEW Setup'; selecting "Digital Capture" and clicking "Next" to create a new data Capture setting; clicking a 'Configurere' button to select pins Pin to be grabbed, setting which Pin data to be grabbed, and clicking 'Next'; setting a name for the rule of the grabbing, distinguishing the rule from grabbing tasks of other pins, and clicking 'Next'; setting parameters of the grabbing task, including: the data grabbing rule (parallel or serial), the number of bits to be skipped, the number of bits to be grabbed by one value, the number of bits to be grabbed by the other value, the number of bits to be skipped after reading the value of one Bit, the value of the next Bit, etc.
Therefore, the data grabbing function of the ATE equipment in the prior art can introduce a large amount of manual operation, and the operation is complicated, so that when aiming at the test item with huge data grabbing requirement, the test item is easy to operate and is wrong, and the test data grabbing error is caused, so that a serious test quality accident of a test result error is caused.
In order to improve the above-mentioned drawbacks, the present disclosure proposes a test result determining method for reducing complexity when capturing test results of a specified row of test vectors, thereby reducing error probability. The following description will be made with respect to a test result determination scheme to which the present disclosure relates.
In the disclosed embodiment, two comparison levels, a first comparison level R1 and a second comparison level R2, are defined in advance within the ATE equipment.
Wherein the first comparison level R1 and the second comparison level R2 represent levels of opposite meanings. For example, in some embodiments, the first comparison level R1 may be a high level high (abbreviated as H) and the second comparison level R2 may be a Low level Low (abbreviated as L); in other embodiments, the first comparison level R1 may be a low level L and the second comparison level R2 may be a high level H.
Of course, it should be noted that, in the embodiment of the present disclosure, the first comparison level R1 and the second comparison level R2 are globally quantified, that is, after the first comparison level R1 and the second comparison level R2 are set, the meaning of the level indicated by the first comparison level R1 in each stage is the same, and the meaning of the level indicated by the second comparison level R2 in each stage is the same.
In the embodiment of the present disclosure, when there is a need to grab a test result of a specified row included in the test vector, a tester may mark the specified row in the test vector in advance, where the content of the mark is a preset character, for example, "r. Of course, the preset character needs to be distinguished from the identification "c" of the digital grabbing function of the ATE equipment itself.
When the ATE equipment detects that a specified row marked as a preset character exists in a vector row included in the test vector, the test result determining method provided by the present disclosure can be started to capture the test result of the specified row of the test vector.
As shown in fig. 1, one embodiment of the present disclosure provides a test result determination method applied to ATE equipment, which may include:
s110: and grabbing test output of a specified row marked as a preset character in the vector row included in the determined test vector.
S120: and comparing the test output with a preset first comparison level and a preset second comparison level respectively to obtain a corresponding first comparison result and a corresponding second comparison result.
It should be noted that in the embodiment of the present disclosure, the test output of the designated row is one of the first comparison level R1 and the second comparison level R2, and the test output of the same Pin in the same designated row is constant for the same Pin.
That is, the first comparison result of the test output of the specified row and the first comparison level R1 is one of "two objects to be compared are identical" and "two objects to be compared are not identical"; the second comparison result of the test output of the designated row and the second comparison level R2 is one of 'two objects to be compared are identical' and 'two objects to be compared are not identical'. And since the first comparison level R1 and the second comparison level R2 represent opposite levels, the first comparison result and the second comparison result represent opposite meanings.
S130: and determining a test result corresponding to the test output according to the first comparison result and the second comparison result.
In the embodiment of the disclosure, on the premise that the test result corresponding to the test output is not obtained, the test result corresponding to the test output can be determined through the first comparison result and the second comparison result.
In some embodiments, when two objects to be compared are the same, the comparison result corresponding to the two objects to be compared is output as Pass, and when the two objects to be compared are different, the comparison result corresponding to the two objects to be compared is output as Fail.
Now assume that the following scenario exists: on the premise that the first comparison level R1 is H and the second comparison level R2 is L, the first comparison result corresponding to the first comparison level R1 is Pass, and the meaning of the representation is that the test result corresponding to the test output is identical to the first comparison level R1; the second comparison result corresponding to the second comparison level R2 is Fail, meaning that the test result corresponding to the test output is opposite to the second comparison level R2.
Based on this, in some embodiments, after the first comparison result and the second comparison result are obtained, the level meaning corresponding to the comparison result for representing that two objects to be compared are identical (i.e. the output is Pass) in the first comparison result and the second comparison result may be determined as the test result represented by the test output.
In this embodiment, in the above-described assumed scenario, the level meaning H indicated by the first comparison level R1 corresponding to the first comparison result may be determined as the test result corresponding to the test output, and therefore, the test result corresponding to the test output of the specified row is H.
In addition, in other embodiments, after the first comparison result and the second comparison result are obtained, the level meaning opposite to the level meaning corresponding to the comparison result for representing that two objects to be compared are different (i.e. the output is Fail) in the first comparison result and the second comparison result may also be determined as the test result represented by the test output.
In this embodiment, in the above-described assumed scenario, the level meaning H opposite to the level meaning L indicated by the second comparison level R2 corresponding to the second comparison result may be determined as the test result corresponding to the test output, and therefore, the test result corresponding to the test output of the specified row is H.
From the foregoing, in the embodiments of the present disclosure, by defining two known amounts in advance, and then comparing the unknown amounts with the two known amounts, respectively, and based on which known amount the unknown amount is identical, a specific test result represented by the unknown amount can be determined. In the process, excessive manual operation is not needed, and compared with the prior art, the method has the advantages that a large number of manual operations are needed to be introduced to acquire the specific test result represented by the unknown quantity, so that the complexity is greatly reduced, and the error probability when the test result of the appointed row of the test vector is grabbed is reduced.
In addition, as can be seen from the foregoing description of the prior art, in the prior art, when determining the test result of the specified row of the test vector, a large amount of manual operations are introduced throughout the entire determination process, while in the embodiment of the present disclosure, a small amount of manual operations are introduced to mark the specified row of the test vector with preset characters, and subsequent operations are automatically performed by the ATE device. Since the efficiency of acquiring test results for a single designated row is improved, the efficiency of determining test results thereof can be significantly improved when a large number of designated rows are faced.
Of course, in some application scenarios, there may be multiple designated rows marked as preset characters in the same test vector.
Based on this application scenario, for each specified row, the test output required to grasp the specified row is compared with the first comparison level R1 and the second comparison level R2, respectively.
In some embodiments, in order to ensure that the comparison results are not disordered, and improve accuracy of the subsequently obtained test results, after the first comparison level R1 and the second comparison level R2 are read for each designated row, the test output may be sequentially compared with the first comparison level R1 and the second comparison level R2 according to a certain sequence, for example, the sequence of reading the first comparison level R1 and the second comparison level R2, so as to obtain the first comparison result and the second comparison result which are sequentially arranged.
For example, two level reading time points, respectively T1 and T2, may be preset for each designated row, and T1 is smaller than T2, and it is defined that for each designated row, the first comparison level R1 is read every time T1 arrives, and the second comparison level R2 is read every time T2 arrives. Then in this example, the read timing of the first comparison level R1 is earlier than the read timing of the second comparison level R2 for each specified row.
Correspondingly, when comparing, the test output is compared with the first comparison level R1 to obtain a first comparison result, and then the test output is compared with the second comparison level R2 to obtain a second comparison result, so that the first comparison result and the second comparison result which are orderly arranged are obtained, and the arrangement sequence of the first comparison result is prior to the second comparison result.
In some application scenarios, when there are multiple designated rows, in order to obtain test results of each designated row more quickly, after the first comparison result and the second comparison result which are orderly arranged are obtained, the first comparison result and the second comparison result may be numbered in sequence according to the arrangement sequence of the first comparison result and the second comparison result.
In some embodiments, the first comparison result and the second comparison result may be numbered sequentially from 0, and the latter number is increased by 1 compared to the former number.
As shown in table 1, for the case where there are two designated rows, the numbers of the first comparison result and the second comparison result which are sequentially arranged may be 0-1-2-3, respectively.
TABLE 1
Correspondingly, when determining the test result corresponding to the test output according to the first comparison result and the second comparison result, the target comparison result can be screened out from the first comparison result and the second comparison result; and then, according to the number of the target comparison result, quickly determining a test result corresponding to the test output.
Optionally, when the numbers of the first comparison result and the second comparison result are sequentially increased by 1 from 0, and when the target comparison result is a comparison result for indicating that two objects to be compared are different (Fail), determining, according to the number of the target comparison result, a test result corresponding to the test output may include: when the number of the target comparison result is determined to be even, determining the level meaning that the test result corresponding to the test output is the second comparison level; and determining the level meaning that the test result corresponding to the test output is the first comparison level when the number of the target comparison result is determined to be an odd number.
For the application scenario, referring to the content shown in table 1, when the target comparison result indicates that two objects to be compared are different (Fail), if Fail occurs in odd number (numbered 1), it indicates that Fail occurs in the second comparison level R2 (H), and it can be determined that the test result corresponding to the test output of the designated row (designated row 1) is the level meaning of the first comparison level R1 (L), that is, L; if the even number (number 2) indicates that the first comparison level R1 (L) indicates that the Fail occurs, the test result corresponding to the test output corresponding to the designated row (designated row 2) is determined as the level meaning of the second comparison level R2 (H), i.e., H.
Based on the above, after the designated rows are associated with the numbers of the first comparison results and the numbers of the second comparison results corresponding to the designated rows, the test results corresponding to the designated rows can be quickly determined according to the parity of the numbers of the target comparison results of the Fail, and the effect of improving the determination efficiency can be achieved for the application scenario in which a large number of test results of the designated rows need to be determined.
Optionally, when the numbers of the first comparison result and the second comparison result are sequentially increased by 1 from 0, and when the target comparison result is a comparison result for indicating that two objects to be compared are the same (Pass), determining, according to the number of the target comparison result, a test result corresponding to the test output may include: when the number of the target comparison result is determined to be even, determining the level meaning that the test result corresponding to the test output is the first comparison level; and determining the level meaning that the test result corresponding to the test output is the second comparison level when the number of the target comparison result is determined to be an odd number.
For the application scenario, referring to the content shown in table 1, when the target comparison result indicates that two objects to be compared are the same (Pass), if the object to be compared is the Pass, the odd-numbered object (numbered 3) indicates that the second comparison level R2 (H) is the Pass, and the test result corresponding to the test output of the designated row (designated row 2) can be determined as the level meaning of the second comparison level R1 (H), namely H; if the Pass occurs at the even number (number 0), the first comparison level R1 (L) is indicated as the Pass, and the test result corresponding to the test output of the designated row (designated row 1) is determined as the level meaning of the first comparison level R1 (L), i.e., L.
Based on the above, after the designated rows are associated with the numbers of the first comparison results and the numbers of the second comparison results corresponding to the designated rows, the test results corresponding to the designated rows can be quickly determined according to the parity of the numbers of the target comparison results of the Pass, and the effect of improving the determination efficiency can be achieved for the application scenario in which a large number of test results of the designated rows need to be determined.
In some application scenarios, after the test result of the designated row is obtained, if the Pin corresponding to the designated row has a data conversion requirement, the test result may be converted into a corresponding numerical value according to a preset conversion rule and then output. For example, there are 4 designated rows, and pins corresponding to the 4 designated rows are used for performing a temperature reading test, so after the test results of the 4 designated rows are obtained, L can be converted into 0, H can be converted into 1, and then the test results of the 4 designated rows can be converted into corresponding binary values for output according to a preset conversion rule. Of course, if the following requirement exists, the binary system can be converted into decimal system and then output.
In addition, referring to fig. 2, the embodiment of the disclosure further provides a test result determining apparatus 400, which is applied to an ATE device, the test result determining apparatus 400 may include: a grabbing module 410, a comparing module 420 and a determining module 430.
