Abstract

PURPOSE:To facilitate the study for causes of mispackage of cards by having comparison between the outputs of a selection circuit and a memory at every card selection signal to check the correct or wrong package of cards. CONSTITUTION:The store contents of card registers 31-3N and their corresponding memory 60 can be read into a control part 80 in response to a card selection signal 81. THe part 80 converts the contents of registers 31-3N into a pit parallel form and compares them with the contents read out of the memory 60. When noncoincidence is obtained between both contents, the part 80 stops the advance of the signal 81 and then takes out the read contents of the memory 60, the contents of registers 3X (X=1-N) and the signal 81 via a means (not shown here) to use them for the study of the causes of mispackage of cards.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a card mounting confirmation method for checking whether the name or revision (REVI8ION) of a card mounted on an information processing device is correct.

(Prior Art) A large number of cards on which ICs, LSIs, individual electrical components, etc. are mounted are usually mounted during device assembly to constitute an information processing device. In this case, the card may be mounted in the wrong position, or the card may be incorrectly mounted even though there has been a revision based on a design change or addition of functionality.

Conventionally, the correctness of this type of card mounting has been determined by visually inspecting the characters indicating the card name and revision that are stamped or otherwise displayed on the card.

(Problems to be Solved by the Invention) In this conventional method, card mounting is confirmed with the naked eye, so it takes a lot of time to confirm card mounting and investigate the cause of incorrect card mounting. Furthermore, there is a problem in that the probability of mistakes made by the person assembling the device increases.

(Means for Solving the Problems) The method of the present invention provides an information processing apparatus having a diagnostic processor having a function of bit serially reading and writing the contents of at least some registers in each card constituting the device to be diagnosed. wherein each card has at least a switch for binarizing the card name, and a card name storage circuit in which the output of this switch is set and is incorporated in the bit-serial read/write path; The processor includes a selection circuit that selects a bit-serial read/write path for each card in response to a card selection signal indicating the mounting position of each card in the device to be diagnosed, which is output from a control unit in the diagnostic processor. , and a memory in which the contents to be set by the switch in the card are stored in advance at the address specified by the card selection signal, and the control section controls each output of the selection circuit and memory for each card selection signal. The feature is that the correctness or wrongness of the Sicard implementation can be investigated by comparison.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to FIG. 1, in this embodiment, each IC and LS
Unlike I etc. (not shown), switches 21, 22...
・2N and card register 31.32・Song ・3N and register 41 and 51.42...4N and 5
N cards equipped with N 11.12...IN
and a diagnostic processor 100 having a memory 60, a selection circuit 70, and a control section 8o.

Cards 11, 12, . . . IN are mounted as a mounted body (not shown) K which is provided with inter-card wiring, power supply, external connections, etc. when the device is assembled, and constitute the device to be diagnosed. The revisions of the cards 11, 12, . . . IN at this time are stored in advance in the memo IJ60K along with the card name. The stored address corresponds to the mounting position of each card, and is indicated by the card selection signal 81 output from the control section 8o.

Card 11.12......IN card name and review number are set by switch 21.22 respectively when assembling the card.
...It is binarized by 2NK. This value matches the content of the corresponding address in the memo IJ 60 if a card of the correct revision is mounted in the correct mounting position.

The card name and revision binarized by switches 21, 22...2N are set in card registers 31, 32...3NK, respectively. Card registers 31, 32, songs, and 3N are card 11, respectively.
．． 12...In IN, the control unit 8o at the time of diagnosis
In response to the scan signal 82 from the registers 41 and 51, 42, . . . 4N and 5N are connected in series.

The registers 41 and 51, 42...4N and 5N are for playing part of the original functions of the card 11, 12...IN, respectively, and the scan signal 82 is not input. A bit serial path is not necessarily formed during normal operation.

Each bit serial path described above, which is formed in response to the scan signal 82, is connected to the control section 80 and the selection circuit on a card-by-card basis. The selection circuit 7° selects one of these bit serial paths in response to the card selection signal 81 and outputs it to the control unit 80.

The card selection signal 81 is, for example, an output of a counter that increments in response to a clock of the information processing device.
...N, as a result of which the selection circuit 70 can select cards 11, 12, ...IN. On the other hand, cards 11.12...
・Memo I76 that stores IN card name and revision
Since the address 0 corresponds to the mounting position of each card as described above, it can be set to 1, 2, . . . , N.

Thus, in response to the card selection signal 81, the contents stored in each card register 31, 32, . . . 3N and the corresponding memo I 760 can be read into the control section 80. The control unit 80 converts the contents of the card registers 31, 32, .

As a result of this comparison, if it is found that they match, it means that the mounting of card IX (X=1 to N) at this time is correct. Further, if it is found that there is a mismatch, the control section 80 stops the increment of the card selection signal 810, and reads out the contents read out from the memory 60 at this time and the card register 3X (X=1 to N).
The contents of the card selection signal 81 and the contents of the card selection signal 81 are taken out to the outside by means not shown and used to investigate the cause of the discrepancy, that is, the origin of the incorrect mounting.

(Effects of the Invention) According to the present invention, as explained above, by adopting a configuration that uses a large amount of existing hardware, it is possible to automate card mounting confirmation. It is possible to reduce the number of steps required to confirm card mounting and the probability of erroneous confirmation, and to facilitate the investigation of the cause of erroneous mounting by extracting the contents of the card register and memory, as well as the card selection signal. .
