Description
[ technical field ] A method for producing a semiconductor device
The present invention relates to a field-replaceable unit (FRU) write test system and method, and more particularly, to a FRU write test system and method for determining whether a test apparatus is correct.
[ background of the invention ]
Generally, an FRU is installed in an electronic device (e.g., a computer or a server) to store information related to the electronic device, so as to manage and determine the electronic device, and the FRU installed in the electronic device may be a flash memory (flash memory) or other types of electrically erasable and programmable read-only memory (EEPROM). Conventionally, in a production test process of an electronic device, a tester scans an identification code tag on the electronic device to obtain a part number (part number) corresponding to the electronic device, such as a product number (product number) or a serial number (serial number), and then writes the part number into an FRU and reads the part number to determine whether the FRU is normal.
However, in the testing process, since the electronic devices are mostly identical in appearance, it is often careless that after one electronic device finishes scanning the identification code tag, the tester performs the read-write test on another electronic device, so that the wrong part number is written into the FRU of the electronic device, or the read-write test is repeatedly performed on the same electronic device, so that some electronic devices are judged to be qualified by mistake when they are not tested. To improve the above problems, there is still a need for a better FRU write test system and method.
[ summary of the invention ]
The technical problem to be solved by the invention is to provide an FRU write test system and method, which can avoid resource waste caused by repeated tests, avoid continuous testing when a previous qualified machine to be tested is not dismounted, and avoid misjudging that the next machine to be tested is qualified, thereby increasing the reliability of the test.
To solve the above technical problem, the present invention provides an FRU write test method, which is suitable for testing a machine under test having an identification code tag, and comprises: scanning the identification code label to acquire the identification code; connecting the testing host to the testing machine to determine whether the predetermined storage section of the FRU of the testing machine stores data; when no data is stored in the established storage section, performing a read-write test program on the FRU; when the predetermined storage section has stored data, further determining whether the data in the predetermined storage section matches the identification code; when the data in the predetermined storage section is matched with the identification code, the FRU is still read and written; and outputting a test failed alarm when the data in the predetermined storage section does not match the identification code.
Preferably, the read/write test program further includes: writing the extracted identification code into a predetermined storage section of the FRU; after the identification code is written into the predetermined storage section, reading the data in the predetermined storage section through the test host, and determining whether the read data in the predetermined storage section is consistent with the identification code written into the FRU; when the read data matches the identification code, outputting a test passing message; and outputting a test failed alarm when the read data does not match the identification code.
Preferably, the FRU write test method further comprises: determining whether the identification code retrieved from the identification code tag conforms to a predetermined format; and outputting the warning that the test is not passed when the identification code does not conform to the predetermined format.
Preferably, the identification code is a product number or serial number of the machine under test.
In order to solve the above technical problem, the present invention further provides an FRU write test system, which includes a machine under test, an identification code scanning unit, and a test host. The machine to be tested is provided with an identification code label and an FRU. The identification code scanning unit is used for scanning the identification code label to retrieve the identification code. The test host is connected to the test machine to determine whether the predetermined storage section of the FRU stores data. When the predetermined storage section has no storage data, the test host performs a read/write test procedure on the FRU. When the predetermined storage section has the storage data, the test host further determines whether the data in the predetermined storage section matches the identification code. When the data in the predetermined storage section is matched with the identification code, the test host performs a read/write test procedure on the FRU. When the data in the predetermined storage section does not match the identification code, the test host outputs a test fail alarm.
Preferably, in the read/write test procedure, after the test host writes the retrieved identification code into the predetermined storage section of the FRU, the data in the predetermined storage section is read out to determine whether the read data in the predetermined storage section matches the identification code written into the FRU. In addition, when the read data is consistent with the identification code, the test host outputs a test passing message, and when the read data is not consistent with the identification code, the test host outputs a test failing alarm.
Preferably, the test host further determines whether the identification code retrieved from the identification code tag conforms to the predetermined format, and outputs a test fail alert when the identification code does not conform to the predetermined format.
Preferably, the identification code is a product number or serial number of the machine to be tested.
Compared with the prior art, before the write test process is performed, the present invention detects whether the predetermined storage section in the FRU122 has stored data, and also determines whether the stored data corresponds to the scanned identification code tag, thereby determining whether the machine under test has been tested repeatedly by mistake or is a machine under test that is to be tested for the second time. Therefore, compared with the traditional test mode, the invention avoids the resource waste caused by repeated tests, and avoids the problem that the former qualified machine to be tested is not dismounted and is still tested continuously, and the latter machine to be tested is judged to be qualified by mistake, thereby increasing the test reliability.
[ description of the drawings ]
Other features and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments with reference to the accompanying drawings, in which:
FIG. 1 is a schematic diagram of a FRU write test system according to an embodiment of the invention.
FIG. 2 is a flowchart illustrating operation of the FRU write test system according to the embodiment of FIG. 1.
[ detailed description ] embodiments
The embodiments or examples shown in the figures are expressed in a particular manner as set forth below. It is to be understood that the embodiment or examples are not to be construed as limiting. Any alterations and modifications in the described embodiments, and any further applications of the principles of the invention as described herein are contemplated as would normally occur to one skilled in the art to which the invention relates.
FIG. 1 is a schematic diagram of a FRU write test system 10 according to an embodiment of the invention. As shown in fig. 1, the FRU write test system 10 includes a test host 110, a test apparatus 120, and an identification code scanning unit 130. The apparatus 120 to be tested includes an FRU122 and an identification tag 124, the FRU122 is used to store the related information of the apparatus 120 to be tested, and the identification tag 124 is disposed on the apparatus 120 to indicate the identification code of the apparatus 120 to be tested, for example, a product number or a serial number. The identification code scanning unit 130 is connected to the test host 110, and the test host 110 scans the identification code tag 124 of the apparatus 120 to be tested through the identification code scanning unit 130 to obtain the identification code of the apparatus 120 to be tested. After obtaining the identification code of the machine stage 120 to be tested, the test host 110 is in communication connection with the machine stage 120 to be tested, and performs an FRU write test procedure on the FRU122 according to the obtained identification code.
The following describes the operation of the FRU write test system 10 according to the present invention with reference to FIG. 1 and FIG. 2. First, in step S202, the identification code scanning unit 130 scans the identification code tag 124 of the apparatus 120 to be tested to retrieve the identification code corresponding to the apparatus 120 to be tested. Next, in step S204, the test host 110 determines whether the retrieved identification code conforms to the predetermined format, if so, continues to step S206, and if not, continues to step S218. Therefore, the wrong label can be prevented from being scanned by mistake or the test procedure can be carried out by the wrong object to be tested. For example, if the identifier is a default serial number of a combination of 2 and 4 english characters, then in step S204, it is determined whether the obtained identifier has 2 and 4 english characters, or further determined whether the combination thereof meets a default rule, it should be understood that the above description is only used for illustration, and any format setting or rule of the identifier should be included in the present invention, and is not limited thereto.
In step S206, the test host 110 is communicatively connected to the test apparatus 120, and determines whether the predetermined storage section in the FRU122 of the test apparatus 120 has data stored therein, if not, step S208 is continued to continue the read/write test procedure, otherwise, step S214 is continued. It should be appreciated that if the test apparatus 120 performs the FRU write test for the first time, the predetermined storage section for storing the identification code in the FRU122 has no data stored therein. Therefore, it is able to determine whether the machine under test 120 has been tested repeatedly by determining whether the predetermined storage section stores data.
When the test host 110 determines that the predetermined storage section in the FRU122 of the tool to be tested 120 does not store data, then in step S208, the test host 110 writes the identification code obtained from the identification code tag 124 into the predetermined storage section of the FRU122, and then in step S210, the test host 110 reads the data in the predetermined storage section of the FRU 122. In step S212, it is determined whether the data read from the predetermined storage section of FRU122 matches the written identification code. If so, continue to step S216, otherwise, continue to step S218. In other words, in steps S208 to S212, test host 110 determines whether the data written to FRU122 is the same as the data read, thereby testing whether FRU122 is normal.
On the other hand, if the test host 110 has determined in step S206 that the predetermined storage sector in the FRU122 of the to-be-tested apparatus 120 has stored data, that is, the to-be-tested apparatus 120 is not tested for the first time, the to-be-tested apparatus 120 may be a previously tested apparatus but not detached from the test host 110, or may be a tested apparatus that has failed the test but is to be tested for the second time after being maintained. To determine the above situation, in step S214, the test host 110 determines whether the data read from the predetermined storage section of the FRU122 matches the identification code of the identification code tag 124, if so, it indicates that the scanned identification code tag 124 corresponds to the machine under test 120 connected to the test host 110, and the machine under test 120 is a machine under test to be tested for the second time, and step S208 continues to continue the read/write test procedure. Otherwise, if they do not match, it indicates that the scanned id tag 124 does not correspond to the dut 120 connected to the test host 110, and is likely to be a tested dut that has been tested but not yet dismounted, then step S218 is continued.
In step S216, the test host 110 outputs a test pass message, for example, the test host 110 may notify the user that the test pass through an appropriate output unit, for example, by turning on a green light through an LED, or outputting a test pass screen through a display, etc., to notify the user that the test pass. In addition, in step S218, the test host 110 outputs a test failed alarm, for example, the test host 110 may notify the user that the test failed through a suitable output unit, for example, through an LED to turn on a red light, or through a display to output a test failed screen, etc. In some embodiments, the test host 110 may further output an alarm according to the type of the test failure, for example, by indicating different states such as the identification code not conforming to the predetermined format, the identification code label not conforming to the data in the FRU, the identification code written in the FRU not conforming to the read data, or by directly displaying the type of the test failure in a text or graphic manner through the display.
In summary, before the write test process, the present invention detects whether the predetermined storage section in the FRU122 stores data, and also determines whether the stored data corresponds to the scanned id tag, thereby determining whether the machine under test 120 has been tested repeatedly by mistake or is a machine under test that is to be tested for a second time. Therefore, compared with the traditional test mode, the invention avoids the resource waste caused by repeated tests, and avoids the problem that the former qualified machine to be tested is not dismounted and is still tested continuously, and the latter machine to be tested is judged to be qualified by mistake, thereby increasing the test reliability.
The methods of the present invention, or certain aspects or portions thereof, may take the form of program code. The program code may be embodied in tangible media, such as floppy diskettes, cd-roms, hard drives, or any other machine-readable storage medium, wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine thereby becomes an apparatus for practicing the invention. The program code may also be transmitted over some transmission medium, such as over electrical wiring or cabling, through fiber optics, or via any other form of transmission, wherein, when the program code is received and loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the invention. When implemented in a general-purpose processing unit, the program code combines with the processing unit to provide a unique apparatus that operates analogously to specific logic circuits.
While the present invention has been described with reference to preferred embodiments, it is to be understood that the above disclosure is not intended to limit the embodiments of the invention. On the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Furthermore, the appended claims are to be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
