Test device simulating a plurality of memories and test method thereof

Abstract

The present invention provides a test device simulating a plurality of memories and a test method thereof, which are used for testing a plurality of first memory connectors of a computer. Multiple first access commands are sent out by the computer to the test device through the first memory connectors so as to simulate the access operation for multiple access zones in the memories. The test device comprises a control unit and a test access zone. The control unit is coupled with the test access zone, and the first access commands are received by the control unit. The test access zone is used for simulating the access zones, and the control unit makes responses to the first access commands, and carries out the access operation of the first access commands for the test access zone. In the present invention, one access zone is arranged in a computer memory. The computer memory, different from the hard disk drive, has the characteristics of high reading-writing speed, so the test speed is high. Compared with the hard disk drive, the computer memory also has the advantages of small volume, good vibration resistance and little possibility of damage, so the production and test cost can be reduced.

Description

technical field [0001] The invention relates to a test device, and in particular to a test device for simulating multiple storage devices and a test method thereof. Background technique [0002] In the production process of the motherboard of the computer device, in order to test whether the function of the Serial Advanced Technology Attachment (SATA) hard disk connector of the motherboard is normal, many equipment and consumables are used to test the SATA hard disk connector of the motherboard . [0003] like figure 1 As shown, the motherboard 101 is provided with four SATA hard disk connectors 102a-102d. When testing the SATA hard disk connectors 102 a - 102 d , it is necessary to connect four SATA hard disks 103 a - 103 d to the SATA hard disk connectors 102 a - 102 d of the motherboard 101 . [0004] Of course, the motherboard 101 is also connected with necessary components for testing, such as CPU, memory, hard disk and other components necessary for running the test...

AI Technical Summary

Problems solved by technology

For example: (1) During the test, the connector of the SATA hard disk is easily damaged due to frequent plugging and wear, and a new SATA hard disk must be replaced, which will greatly increase the test cost

(2) In the process of moving and plugging, the SATA hard disk is easily damaged due to collision

(3) The SATA physical hard disk is a magnetic medium. If it is suddenly powered off or placed in a strong magnetic field, it will easily cause damage to the magnetic track, and it is not easy to repair

(4) When testing, as many SATA connectors as there are on the motherboard, how many physical hard disks are needed, and each physical hard disk will occupy a certain space, so if the motherboard has multiple SATA connectors, it will make the test A large space is required for testing, and multiple SATA hard disks need to be purchased, which increases the cost of testing
