Filed: 1988-07-21
Abstract: PURPOSE:To reduce planning cost and part cost by realizing a circuit part susceptible to a scanning test on a printed circuit board and a circuit insusceptible thereto by the same LSI. CONSTITUTION:At the time of a scanning test by an LSI alone, by falsely setting a scanning test prohibiting signal 16, a system lock 13 and a scanning test signal 15 are inputted to the first and second circuit parts 11, 12 and the scanning test using a scanning path is performed. At the time of the scanning test on a printed circuit board, by really setting the signal 16, a special lock 14 is inputted to the circuit part 12 in place of the system clock 13 and the route of the scanning path corresponding to the circuit part 12 is bypassed. Further, since the input of the signal 15 to the circuit part 12 is suppressed, the circuit part 12 is removed from the subject of the scanning test. During this time, the system lock 13 and the signal 15 are inputted to the circuit part 11 and the scanning test on the printed circuit board of the circuit part 11 is performed without exerting effect on the circuit part 12.

Title: Power source noise removing system
Inventor: AMAMIYA SHINICHI
IPC: H02M1/14
Filed: 1984-08-31
Abstract: PURPOSE:To preferably remove a power source noise by extracting and storing a power source noise pattern from an input, synchronizing it with the power source noise pattern stored in advance, and subtracting it. CONSTITUTION:A power source noise removing system is composed of adders 1, 2, a delay circuit 3, and an attenuator 4. The adder 1 subtracts the output of the delay circuit 3 by an input signal N, and outputs the result as an output signal OUT. The adder 2 inputs the output of the attenuator 4 and the output of the delay circuit 3. Thus, when the power source noise S of the first period is input to the adder 1, the delay circuit 3 stores the power source noise S of A times (0.01 times), and when the power source noise of the second period is input, it similarly stores. Then, the pattern S is fed to the adder 1, which subtracts the power source noise pattern S fed to the attenuator 4 from the input signal IN and outputs it.
