Description

[Detailed description of the invention]

The present invention relates to a method for collecting expected diagnostic values necessary for creating a diagnostic program for an information processing device from normal devices of the same type, and relates to a method for creating expected diagnostic values that can perform not only collection but also extraction and editing at the same time as specified. When creating such a diagnostic program, collection, extraction, and editing have conventionally been processed and processed individually as separate functions, as shown in Figure 1.
A method of implementation was adopted. However, in such a conventional method, expected value data including only necessary portions at successive points in time is collected, and computer processing is required three times: collection, extraction, and editing. This resulted in the following drawbacks. a. Requires a large number of storage media to store expected value data. b. It takes a long time to collect. c. Collection, extraction, and editing are performed separately, requiring computer time and manpower each time. Furthermore, computer time includes time used to process data that will eventually become unnecessary. The present invention enables extraction and editing at the same time when collecting expected values to be incorporated into a formal diagnostic program, solves the drawbacks of the prior art, and provides a diagnostic method for efficiently and economically developing a diagnostic program. The objective is to provide a method for creating expected values. As shown in FIG. 2, the present invention first collects the part included in the expected value for a sample case, and then analyzes the data manually and collects and collects the data according to the extracted data and specified editing data. It is possible to extract and edit at the same time and create all diagnostic expected values. Hereinafter, the present invention will be explained in detail using examples. The expected value creation method of the present invention operates on the hardware configuration shown in FIG. This is realized by the expected value creation program shown in FIG. First, an overview of the operation of this system will be explained with reference to FIG. The diagnostic processing device 31 includes a magnetic tape device 32-
The expected value creation program (FIG. 4A) is read into the storage device 33 from a. According to the operator's instructions from the console 34, the diagnostic processing device 31 executes the expected value creation program up to any stage of collection, extraction, and editing. In collection, the normal device 35 executes the diagnostic test from the expected value creation program and logs out the results (expected values) to the storage program. The logged-out expected value data is extracted and edited according to control data from the card reader 36. Further, the edited expected value is recorded on the magnetic tape 32-b. To explain other uses of the device, the magnetic tape 32-c is used when extracting/editing control data is provided from a magnetic tape rather than a card. The line printer device 37 is for outputting expected value collection/extraction/editing designation data and processing result notifications. Note that S ₁ represents a diagnostic load store bus, S ₂ represents a store and logout bus, S ₃ represents a load bus, and S ₄ represents a diagnostic control signal line. Next, the features of this system will be explained in detail with reference to FIG. It is assumed that each component device is in operation and the expected value creation program is loaded onto the storage device. The following describes the collection and collection shown in Figure 2.
This is a case where expected values of all diagnostic tests are created by successively extracting and editing. First, operator instructions from the console 4 specify the range of diagnostic tests for which expected values are to be created (in this case, all tests) and the execution stages of expected value creation (i.e., collection, extraction, editing, all stages in this case). confirm. Therefore, the control parameter interpretation module 43 interprets the instruction content read by the instruction from the control module 42, and displays an execution test table (consisting of a start test number and a final test number) and an execution stage table (consisting of a start test number and a final test number). Create a pointer (initial value 0, which will be incremented by a predetermined number) and a pointer (initial value 0). Next, the expected value creation control data 44 is read in accordance with instructions from the control module 42, and the control parameter interpretation module 43 reads the extraction table (area data corresponding to each diagnostic test group and clock data corresponding to each diagnostic test). (consisting of data). With the above, preparations for creating expected values are complete, and collection of expected values begins. For such collection, the normal device 45 operates according to instructions from the control module 42, executes a diagnostic test given from the collection module 46 (read in the storage device 33 in FIG. 3), and stores the internal state in the storage device. Logout to a specific area (the timing of this logout is determined by the clock data of the extraction table, etc.).
The collection module 45 reads this logged-out internal state (signal group) as a collection expected value (expected value data) 47 . Next, according to an instruction from the control module 42, the extraction module 48 extracts only the area specified by the area data in the extraction table as the expected extraction value 49. Then, in response to an instruction from the control module 42, the editing module 50 adds region data for each diagnostic test group and clock data for each diagnostic test to the extracted expected value, and converts these into relative format to create the edited expected value 51. Output. This edited expected value is further written on the expected value recording magnetic tape 52. The contents of this magnetic tape 52 are used and incorporated with the diagnostic test and diagnostic control program when editing the diagnostic program. Each time each of the above three execution steps is completed,
The pointer of the execution stage table is incremented by a certain number, and when the pointer reaches the value indicating the edit stage execution or more, the processing of the expected value creation program ends. The method of specifying the execution test and execution stage and the format of the expected value creation data in the above expected value creation process will be described below. First, the method of specifying the execution test and execution stage input by the operator from the console is as follows. RQmode, [testno.1] [―testno.2], 9999 CR
Above, RQ and CR indicate pressing the request and return function keys. Each parameter has the following meaning: mode: Specifies the execution style. That is,
Starts execution from the test number indicated by testno.1 and executes until the final test number, executes from the first test number until testno.1,
Select and specify one of the three modes of execution from testno.1 to testno.2. testno.1: Test number to start or end execution. Whether it starts or ends depends on the mode. testno.2: Execution end test number. 9999: Instructions to what stage to execute. However, in the case of only collection, it is possible to specify how to give the collection start clock. Examples and meanings of specific specification methods are as follows. 0000: Execute only collection. Start clock is 0 (initial state) 1000: Executes only collection. The start clock is specified for each test group and its value is subsequently entered. 2000: Executes only collection. The start clock is specified for each test number (unit test) and entered following that value. 3000: Perform collection and extraction. The extraction clock and area designation are given as expected value creation data. 4000: Execute collection/extraction and editing. The extraction clock and area designation are given as expected value creation data. Next, the format of the expected value creation data is shown below.
First, the data has the following structure. TID d sss bbb CMP aaa, a′a′a′ : EXC uuuu, ccccc―c′c′c′c′c′ : TID d s′s′s′b′b′b′ : In the EMD configuration , the meaning and format of each data element are as follows. TID: Specify the test group number (processing unit) to be executed. d indicates the device type,
sssbbb indicates the test group to be executed. CMP: Specify the area of logout data (internal state) to be extracted as the expected value (consisting of several CMP data). The detailed format is as follows. CMP aaa, a′a′a′ [, n
[oooooooooooo]] aaa: Extraction start address specified by the CPM data. a′a′a′: Extraction end address specified by the CPM data. n: Specify the interval from aaa to a′a′a′ to be extracted. It can be omitted when n=1. oo...oo: Specifies which pit of the extraction target address the signal corresponding to is to be extracted (expressed in octal notation). Note that this step can be omitted if all pits of the target address are extracted. EXC: Data that specifies which clocks are collected and extracted as expected values. As a variation of this, there is also EXI (selection based on instructions) shown below. EXC uuu, ccccc-c′c′c′c′c′ uuuu: Test number within the test group (minimum test unit). ccccc: Collection/extraction start clock c′c′c′c′c′: Collection/extraction end clock uuuu and both clocks can be specified with zero subres. Next, we will explain EXI as a modification of the above EXC. EXI uuuu,n[-n′][,aaa-bb-v
[-t]] n: Extraction start instruction number [Sequential number within the test instruction series] n': Extraction end instruction number [Sequential number within the test instruction series] The following parameters are This indicates which time point to extract. aaa-bb-v [-t]: Specifies the extraction target timing.

[Table] v: Value of target signal (specify “0” or “1”) t: Specify that the expected value of the t-th clock is collected and extracted after the specified signal takes the value v. EMD: Indicates the end of expected value creation data. According to the present invention as described above, the period for creating expected values, the number of media required for creating expectations, computer time, and man-hours can be significantly shortened or reduced. The reasons and effects will be explained in detail below. 1. Reduction in the number of media Compared to a case where only the start and end clocks to be collected can be specified, the method of the present invention reduces the number of clocks to be collected from 40 to 50 volumes (2400 feet) to 1 volume (1200 feet) on a super large computer. . 2. Reduction of computer time The majority of the computer processing time for collection, extraction, and editing is spent writing or reading expected values to or from a medium. Therefore, since the method of the present invention only writes in one volume,
Significant time savings. In the case of a super large computer, preparation and media reading,
The processing time excluding write failures is expected to be reduced from 18 hours to 1 hour (5.6%). In particular, the larger the size, the greater the amount of time saved. 3. Reduction in man-hours By reducing computer time, the man-hours for use are reduced, and by reducing the creation process, the man-hours for processing requests are reduced. In addition, the time required to prepare the computer for use and to request reuse or processing in response to errors (writing/reading from/on media) is also reduced. 4. Reducing the time required to create expected values Since the computer usage time has been reduced, the period can be shortened since there is a limit to the usage time per person per day. The production period is also shortened due to the simpler production process and the reduction in the number of reworks. 5. Reduction in the cost of creating expected values For reasons 1 to 3, it is possible to reduce the cost of creating expected values. As described above, according to the present invention, it is possible to shorten the diagnostic program development period and reduce costs. This becomes more effective as the target computer becomes larger. It should be noted that the present invention is not limited to the above-mentioned embodiments, and the following alternative methods can be used. 1. In the embodiment, it has been explained that it is possible to specify how much of the collection/extraction and editing should be executed, but it may also be possible to instruct the execution from any point after this execution stage. Further, it may be possible to instruct only which stage to be executed. 2. When collecting samples, it is also possible to add a function to edit and list the internal status (logout data) for each clock. 3 Operator instructions may be entered by card. 4 Expected value creation data is on the magnetic tape 32 in Figure 3.
