A self-functional detection system for TAP controller and a method thereof are disclosed. In the system, a TAP controller includes a DCM circuit, and a data device can obtain and display a voltage signal, a GPIO signal and a high-speed signal from the DCM circuit through an API, to implement detection for an internal circuit of the TAP controller. Alternatively, the TAP controller is electrically connected to the external function detection module device, the data device obtains the JTAG signal from the DCM circuit through an API and displays the JTAG signal, so as to detect whether the communication port function of the TAP controller works normally, and further detect whether an external connection of the TAP controller works normally. Therefore, the technical effect of providing self-functional detection of a TAP controller to determine occur point of test error accurately may be achieved.

A dummy dual in-line memory module (DIMM) testing system based on boundary scan interconnect and a method thereof. A dummy dual in-line memory module functioning normally is used as a test fixture, a dummy dual in-line memory module under test is served as an unit under test (UUT), and the test fixture and the unit under test are inserted into a test device to electrically connect to each other, so that the test access port (TAP) device can perform boundary scan to control the test fixture to test the unit under test through signal pins, and check a test result based on a data signal collected from at least one boundary scan register. Therefore, the effect of improving testing convenience of the dummy DIMM can be achieved.

A DDR5 SDRAM DIMM slot detection system and a method thereof are disclosed. A first detection board is serially connected to a second detection board, a JTAG controller converts a DIMM detection instruction, which is generated by a detection device, into a DIMM detection instruction in JTAG format; the DIMM detection instruction in JTAG format is provided to the first detection board or second detection board through the adapter circuit board, so as to detect DDR5 SDRAM DIMM slots of the circuit board under test, thereby achieving the technical effect of improving efficiency in detection for DDR5 SDRAM DIMM connection interface.

A function verification method for a boundary scan test controller is disclosed. In the method, the configuration positions of input/output connectors on a test board correspond to configuration positions of to-be-verified connectors on a boundary scan test controller, so that when the test board is stacked and positioned on the boundary scan test controller, the input/output connectors can be electrically connected to the to-be-verified connectors corresponding thereto, respectively. After being electrically connected to the boundary scan test controller via a USB port, the test control host creates a test script according to information of the test board and all operations of the to-be-verified connectors, and then execute a test program in the to-be-verified connectors according to the test script, and generates a test report, and determines whether the boundary scan test controller meets shipment or production requirement according to the test report.
