| abstract | PURPOSE: To enable execution of a test of high precision by a simple test circuit board and a signal generator by a method wherein an output signal of an internal logic circuit to be tested and an input signal at the time of an actual operation are taken in an input buffer selectively. n CONSTITUTION: Input buffers 5 to 7, an internal logic circuit 14 and output terminals 11 to 13 thereof and a basic test signal input terminal 15 are provided. A switching signal is inputted to a switching terminal 4 to put the buffers 5 to 7 in a test mode, and a test signal is impressed on the terminal 15 from the signal generator. Then the circuit 14 starts to operate, a logic output signal thereof is outputted to the terminals 11 to 13 and also inputted in feedback to the buffers 5 to 7, the signal thus inputted is given as a new test signal to the circuit 14, and thus a test is continued. On the occasion, input terminals 8 to 10 are made open to maintain a potential of a set level and thereby execution of a test of the circuit 14 is enabled. According to this constitution, it is possible to simplify a wiring of a test circuit board, to lessen the number of test signals and to execute a test of excellent precision. n COPYRIGHT: (C)1990,JPO&Japio |
