ABSTRACT
Several authors focused on testing of digital integrated circuits and their different test
scenarios are proposed. No author speaks about the testing of the monostable multivibrator on
the board. In this paper, a novel circuit design methodology is presented to test the
monostable multivibrators functionally on the board. To test the monostable multivibrators
properly, the time duration needs to be measured accurately. This method is based on the
signature generation of the output of the monstable multivibrators. The measurement of the
time duration is considered the signature that expresses the proper functionality of the
monstable multivibrators. This testing design was implemented and applied to different pulse
durations. The experimental results indicate the high accuracy of the proposal design
approach. The measurements in the millisecond range had not any deviation from the setting
pulse. The measurements in the microsecond range had small deviation from the setting pulse
± 1%.
