1. Field of the Invention
The present invention relates to a testing apparatus, and more particularly to a testing apparatus for a SATA port of a motherboard.
2. General Background
A typical motherboard has a plurality of Input/Output ports; for example, a Universal Serial Bus (USB) port, parallel ports, serial ports, and a serial advanced technology architecture (SATA) port. The motherboard is coupled to peripheral devices via the Input/Output ports to form a computing system.
Motherboards must be tested for quality before shipment. Conventionally, in test, a peripheral device is coupled to a motherboard under test via a corresponding Input/Output port to test whether the corresponding Input/Output function works well or not. For example, a SATA hard disk drive is coupled to the motherboard via a SATA port to test the SATA function. However, a conventional SATA hard disk drive is expensive, and this can increase the cost of testing. Furthermore, the SATA hard disk drive includes high precision moving mechanical parts. Consequently, the SATA hard disk drive is relatively slow, consumes significant amounts of power, and is prone to reliability problems especially if it sustains external shock or vibration. If the SATA hard disk drive operates unreliably, this may compromise the accuracy of the test.
What is desired, therefore, is a testing apparatus which economically and efficiently replaces a conventional SATA hard disk drive in the testing of a motherboard.
In one preferred embodiment, an apparatus is provided for testing a serial advanced technology architecture (SATA) port of a motherboard. The apparatus includes a flash memory chip, a first signal converting chip electrically connected to the flash memory chip, and a second signal converting chip electrically connected to the first signal converting chip. The first and second signal converting chips cooperate to convert a flash memory signal to a SATA interface signal.
Other advantages and novel features will become more apparent from the following detailed description of a preferred embodiment when taken in conjunction with the accompanying drawings, in which:
Referring to
The apparatus 30 includes a flash memory chip 31, a first signal converting chip 33, a second signal converting chip 35, and a SATA connector 37, all of which are electrically connected in sequence. The flash memory chip 31 has a predetermined storage capacity and is used as a substitute functional device of a functional component like the SATA hard disk drive electrically connectable to the motherboard. The first signal converting chip 33 is an IDE-flash (Integrated Drive Electronics-flash) signal converter, for converting between IDE interface signals and flash memory signals. The second signal converting chip 35 is a SATA-IDE signal converter, for converting between SATA interface signals and IDE interface signals.
In test, the apparatus 30 is connected to the SATA port of the motherboard under test via the SATA connector 37. The motherboard sends a test signal of request to the apparatus 30. The flash memory chip 31 feeds back a flash memory signal which contains information of storage capacity. The flash memory signal is first converted to an IDE interface signal by the first signal converting chip 33. Then, the IDE interface signal is converted to a SATA interface signal via the second signal converting chip 35. The SATA interface signal is sent to the motherboard under test via the SATA connector 37.
Referring particularly to
The apparatus 30 simulates the function of a conventional SATA hard disk drive in the test. The apparatus 30 is cheaper than the SATA hard disk drive. Furthermore, the apparatus 30 has three chips instead of moving mechanical parts as required by the SATA hard disk drive. Therefore, the apparatus 30 is more reliable, as well as being faster and consuming less power than the SATA hard disk drive.
It is believed that the present embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the example hereinbefore described merely being a preferred or exemplary embodiment.
