DIGITAL EQUIPMENT INSPECTION DEVICE AND DIGITAL EQUIPMENT INSPECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an inspection device and an inspection method for automatically inspecting a plurality of output terminals (interfaces) of digital equipment (circuits), by preventing abnormal check mistakes by a difference in test patterns, or the like, and without overlooking changes in data for a specified period of time.;SOLUTION: Data, where only one terminal in output terminals becomes "1" and all remaining terminals go to "0", if a video circuit 100b operates normally, are generated for a specific period and are inputted to the video circuit 100b, namely digital equipment having a specific number (N) of output terminals by a signal generation means 100a. Further, terminals that go to "1" for each specific period passage are changed successively, and the data are inputted to all specific number (N) of the terminals. An inspection section 200 monitors the output of each output terminal in the video circuit 100b for a specified period and compares an N-bit value after monitoring with a normal N-bit value for deciding the quality of the video circuit 100b.;COPYRIGHT: (C)2004,JPO&NCIPI
