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.

Self-functional detection system for tap controller and method thereof

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.
