Method and apparatus for isolating faults in a logic circuit
TL;DR: In this paper, a portable processor-oriented digital tester and method for isolating faults in digital printed circuit boards under test is presented, which includes a processor, a main memory and a plurality of driver/sensor circuits.

TL;DR: In this paper, a program is developed for testing printed circuit boards by applying a proposed test program to a board which is initially in an arbitrary response state, comparing the resulting response pattern with a reference, modifying the proposed program if necessary to obtain a valid comparison, running the program on the board successively while faults are applied to selective board input nodes, determining penetration of the faults through the board by analyzing the toggle signatures of the response nodes, and again modifying the program again if necessary.

Complex logical fault detection apparatus and method
Eric Sacher,Thomas E. Trebelhorn +1 more
TL;DR: In this article, a known good identical logic circuit is stimulated by a preselected sequence of binary test patterns and the number of transitions in logical state before achieving a final logical state as well as the final logical states for a number of points within the circuit are monitored and saved.
