Abstract
The present disclosure illustrates a testing circuit board with self-detection function and a self-detection method. A test for a to-be-tested circuit board is executed and a self-detection for a testing circuit board is performed by a JTAG chip. After the self-detection is passed, a first JTAG connection interface and a second JTAG connection interface are conducted by a controller, a multiplexer and a switch chip, to connect test circuit boards in series. Therefore, the efficiency of solving self-detection of JTAG chip with series connection conveniently and quickly may be achieved.
