[Prior Art] Conventionally, the method of substrate testing is mostly performed on the surface of the substrate by the probe method. The so-called "plug-in circuit test (10) is also (4), ft (4)" to know that the function of the device is normal. No, however, with the continuous development of the production technology of computers and various information products (4), and the design orientation of today's electronic information products are thin and short, the interior of various electronic products and the boards are installed. The number and density of wafers and components are rapidly increasing, resulting in the pitch of the foot ends of the mounted components, which has gradually become smaller than the pitch of the probes. Therefore, the conventional plug-in circuit test method cannot meet the needs of today. Therefore, the test method of the other side is rJTAG (so-called Boundary Scan Test), and the so-called JTAG job method is to sequentially scan all external input and output terminals of the integrated circuit components. 'Retrieve the test data of the output of the input, the element: the internal function' and the general test method, which can be used for the error insertion of the component, the input/output signal monitoring between the external circuit and the component, and the component The mutual test, and the _ logic circuit Wei test, not only the test is convenient 'and because of the fast prisoner', so it is well received by various manufacturers, 13170021 welcoming 'in addition' through the external computer host can JTAG, test, in use Extremely flexible. The chip or microprocessor under development has a JTAG interface for _ or debugging. However, when the chip or microprocessor is developed, the device interface usually has no chance to be used. The system is a thin electronic product. If you want to test it, you need to dismantle it and add a soldering interface on the JTAG signal line before you can fine-tune, debug or _view. It is not only inconvenient. And often • Touching electronic products causing damage 'so that's there is a kind of industry--"JTAG debugging interface (Debugging (10) 咐 ))", the debugging interface has USB (Universal Serial Bus) The connection port and the control chip are connected to an electric device by means of the USB port, so that the control chip can quickly debug and program the electronic product, which is convenient and flexible. It is very popular among users and workers related to electronic products. φ In addition, for another test of "System-On-Chip" (S0C), the same problem as the above JTAG test 4 is encountered, that is, a general non-synchronous transmission and transmission is provided on a general wafer system.
