INSTRUCTIONS: [Technical Leadership of the Invention] The present invention relates to a general-purpose debugging assistance device, and more particularly to a general-purpose SAS interface debugging assistance device. [Prior Art] Serial Attached SCSI (SAS) is a high-speed transmission and support for dual-port hard disk interface technology. It is compatible with SAS/SATA (serial-scale) interface and can be accessed. The expander expands the connection function, so it can be applied not only to the server but also to various storage devices such as a disk array (RAID). At present, with the continuous upgrade of the SAS protocol version and the increase of the transmission speed, the requirements for the Debugging method are getting higher and higher, but there is no effective and simple auxiliary device on the market to help the SAS interface to locate and solve the communication. Signal errors that may be encountered during electronic product development and operation. m In the current SAS interface product development and post-operation maintenance process, the conventional debugging method is to directly connect the SAS Protocol Φ Analyzer such as SAS Tracker (SAS TRACER) with multiple cables. Between the initial device (Initiator) and the target device (Target), and perform data packet capture, protocol decoding, statistical analysis and other debugging functions. However, such a conventional debugging method using a simple cable connection has the following disadvantages: 1. The target device must be exposed to a place where the connection cable can be plugged and unplugged. When the connection interface of the target device is in the deep inner part of the chassis or the rack in the upper part, it is extremely inconvenient for the operator to plug and unplug the cable in the narrow chassis space or on the upper frame; In some designs, the SAS interface will need to carry some transmissions of the external frequency signal 201018941 - (0ut_of-Band signaling), such as the control signal for the hard disk error light signal. If the conventional storage method by wire connection is used, the external frequency signals will be lost after passing the protocol analyzer, which will destroy the integrity of the system function. In view of the above shortcomings, especially in the case where the current signal transmission rate is required to be 3 〇 and 6 GHz, it is difficult to ensure the reliability of signal transmission by the conventional method of connection. In order to solve the above problem, the prior art has proposed a (four) auxiliary card, which includes a plurality of interfaces, and when the debugging operation is performed, the initial device card, the target device, and the test device are simultaneously connected, and the line is reduced. The use of the cable, the connection stability, and convenient on-site operation, easy to insert and pull. However, the conventional debug auxiliary card needs to connect multiple devices at the same time, and the circuit design and structural design are complicated, which is not conducive to lowering the cost. Therefore, it is necessary to provide a novel debugging aid to overcome the shortcomings of the conventional debugging auxiliary card. SUMMARY OF THE INVENTION One main object of the present invention is to provide a universal debugging auxiliary device, which has low circuit design complexity, easy realization of structural components, wide application range, low cost, high connection stability, convenient on-site operation and insertion and removal. easily. Another object of the present invention is to provide a universal debugging assistance device that can avoid losing the external frequency signal 'to maintain the integrity of the system function.>> Other objects and advantages of the present invention can be further derived from the technical features disclosed in the present invention.

Therefore, the present invention can maintain the integrity of the system function while performing the debug program. In addition, according to the needs of the operator, the control of the switching element 26 can control the backplane 41 or the hard disk 43 to transmit the external frequency signal, or cover the external signal transmitted by the backboard 41 or the hard disk 43, or even the virtual back. The external frequency signal is transmitted by the board or the hard disk, so that the function of the transmission control of the external frequency signals and the function of changing, reconstructing and simulating the external frequency signals can be realized. Therefore, the universal debugging auxiliary device of the present invention has better debugging. flexibility. The universal debugging aid of the present invention can add more starting device cards! Or the target device card 2, for simultaneous use between _ target devices and multiple start devices, or for simultaneous debugging of multiple target devices and one start device, and also for detecting multiple target devices and The debugging between multiple initiating devices is the same as above and will not be described. In the above application example, the length of the card 10 of the initial device card 1 is slightly greater than or equal to the length of the hard disk 43. After the chassis 42 is inserted, the initial interface I2 of the initial device card i and the external frequency signal are The interface ls is exposed to the outside of the chassis to facilitate connection with other devices. (4) The initial device card 1 is located in the chassis 42, so that the power supply can be directly provided by the backboard 41, and (4) the power supply terminal of the sas connection (4) on the backplane 41 is used as the power source corresponding to the start & The terminal supplies power to the starting device card 1 2010 18941 • Source. The initial device card 1 can also be provided with a power socket (not shown) for connecting to an external power supply device (such as a 220V power supply) to supply power to the universal debugging auxiliary device. The principle is the same as that of the target device card 2, and will not be described. . Referring to the seventh figure, the general error debugging auxiliary device of the present invention is used for an application example of the debugging of the hard disk 43 itself in the storage device. When the line between the hard disk 43 and the backplane 41 is good and only the hard disk 43 itself has a problem, the universal error assisting apparatus of the present invention can be connected to a SAS/SATA information generator 6 to detect the hard disk 43. The first target device interface 22 of the target device card 2 of the universal debugging auxiliary device of the present invention is connected to the corresponding interface of the hard disk 43 e, and the first target external interface 21 is consumed by the SAS/SATA resource generator 6 ′ only for information. The SAS/SATA information generator 6 communicates with the hard disk 43 and the SAS/SATA information generator 6 issues a test signal to judge and debug the problem of the hard disk 43 according to the response of the hard disk 43.
