Embodiment Construction

[0011] Please refer to figure 1 The SATA interface testing device of the present invention includes an indicating device 110, a temporary register 120, a signal converter 130 and a SATA interface 140 for being connected to the SATA interface on the board to be tested, and the number of the SATA interfaces 140 can also be Multiple, to test multiple SATA interfaces on the board under test at the same time. The indicating device 110 is connected to the register 120 , the register 120 is connected to the signal converter 130 , and the signal converter 130 is connected to the SATA interface 140 . The temporary memory 120 has a certain storage capacity and is used to simulate the storage function of a hard disk and store preset test programs. The signal converter 130 can read the content of the temporary register 120 and convert it into a serial signal and output it to the SATA interface 140, and can also receive a serial signal from the SATA interface 140 and convert it into a par...

Abstract

An SATA interface testing device comprises a latch register, an indicating device, a signal converter and at least an SATA interface. The indicating device is connected with the latch register; the latch register is connected with the signal converter; the signal converter is connected with the SATA interface; the signal converter receives the serial data from a board to be tested through the SATA interface and then converts the serial data into the parallel data for the latch register to implement the data read-in check; after the check, the data is converted into the serial signal through the signal converter and the serial signal is output through the SATA interface to the SATA to be tested for data read-out check through the inner procedure of the board to be tested; the indicating device indicates whether or not the SATA interface on the board to be tested is good according to the check result. The invention also discloses an SATA interface testing method. The device and the method need no hard disc when testing the function of the SATA interface of the mainboard, thus not affecting the testing result due to the vibration of the hard disc and reducing the testing cost.

Description

technical field [0001] The invention relates to a SATA (Serial Advanced Technology Attachment, serial high-level configuration) interface testing device and testing method. Background technique [0002] Commonly used hard disk interfaces on motherboards include IDE (Integrated Drive Electronics, integrated electronic drive), ATA (Advanced Technology Attachment, advanced configuration) and SATA. Among them, the SATA interface has a higher data transfer rate and fewer pins than the former two, so it is more in line with the development trend of future interface standards. [0003] After the main board is assembled, it needs to go through a comprehensive functional test, including the test of various interfaces on the main board. When testing the SATA interface of the motherboard, the test is usually performed by connecting the SATA hard disk to the SATA interface of the motherboard. However, because the price of the hard disk is generally high, and it is easy to affect the t...
