PROBLEM TO BE SOLVED: To enable a boundary scan test, even if a sequential circuit is provided between devices. SOLUTION: This boundary scan test device to inspect input/output of a signal between a first circuit 2 and a second circuit 3 is provided with a test signal supply means to supply a clock action signal to act as a clock, and a test signal outputted from the first circuit 2 at a proper time, a result signal takeout means to take out a signal inputted to the second circuit 3 as a result signal, and a determination means for determining the propriety of the transmission of signals between the first circuit 2 and the second circuit 3 is proper or not based on the clock action signal and test signal supplied at a proper time, and the result signal taken out at a proper time. |
