Abstract
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.
