Problems solved by technology

[0013] Soft failure means that a failure has been found, but its failure phenomenon is difficult to replicate, and it may take a long time for aging tests to replicate the failure phenomenon
[0014] Motherboard test: This kind of problem may be caused by an occasional error report during the long-term aging process of the client platform due to various reasons (such as the occasional temperature rise of a certain memory particle during aging), but it is difficult to replicate the failure phenomenon. Will be judged by us as an NTF note
This type of failure replication requires a test run long enough (some take a week or two) for burn-in tests to replicate the phenomenon

Embodiment 1

[0024] A method of simulating the ECC ERROR generation device of the memory, select one of the 64-bit data signals, and perform switch switching action on the hardware through the adapter card-the two ends of the switch are respectively connected to the DQ signal and the GND signal, when the switch switches Finally, DQ and GND are short-circuited, and the signal transmission error is artificially created to identify whether the main board has the ECC function.

[0025] For example, the series of signals sent by the IO of the controller are 10101101. After the artificial switch is short-circuited, the signal is continuously low level 00000000. In this way, if the motherboard system has the ECC function, it will automatically identify and correct the error, and reflected in the PMC. If the motherboard does not have the ECC function, the system may crash or other failures due to switching of this switch, and it will be reflected in the PMC system.

Embodiment 2

[0027] On the basis of Embodiment 1, the DQ signal and GND signal corresponding to this embodiment can be found according to the golden finger pin number.

Embodiment 3

[0029] An adapter card for analog memory ECC ERROR, the adapter card is provided with a switch, and the two ends of the switch are respectively connected to the DQ signal and the GND signal, and when the switch is switched, the DQ and GND are short-circuited.

Abstract

The invention discloses a method for simulating a memory ECC (error checking and correcting) ERROR generation device. The method comprises the steps of selecting one bit from a 64-bit data signal and performing switch switching action on hardware by a switching card, wherein two ends of the switch are respectively connected with a DQ signal and a GND signal, when the DG and GND are short-circuited after the switch is switched, manually manufacturing a signal to transmit the signal to identify that whether a main board has the ECC function or not. By the method, the ECC error can be generated by simulation, and the detection capacity of a main board platform BIOS on the error can be examined.

Description

technical field [0001] The invention relates to a method for simulating a memory ECC ERROR generating device. technical background [0002] ECC is the abbreviation of "Error Checking and Correcting", and the Chinese name is "Error Checking and Correcting". ECC is a technology that can realize "error checking and correction". ECC memory is the memory that uses this technology. It is generally used in servers and graphics workstations, which will make the entire computer system more secure and stable when working. . [0003] Memory is an electronic device, and errors will inevitably occur during its working process. For users with high stability requirements, memory errors may cause fatal problems. Memory errors can also be classified into hard errors and soft errors according to their causes. Hardware errors are caused by hardware damage or defects, so the data is always incorrect; soft errors occur randomly, such as sudden electronic interference near the memory and other...
