Abstract
PURPOSE: To test plural circuit blocks having the same function simultaneously to make the test efficient, by subjecting logical outputs of respective circuit blocks, which are obtained by input signals of the concentric level, to analogie addition and by using the addition output level.
CONSTITUTION: Reset signal R, clock signal CL, and signal D are given to FFs D1WDn simultaneously, and output signals q1Wqn of respective FFs are added by operational amplifier A to obtain polarity inversion signal OUT. By detecting the level of this signal OUT, functions of respective FFs can be tested simultaneously.
