Abstract:

As the combination circuits used in digital computers can be regarded as single-cycle automata, a method of setting up tests for determining failures in such automata is suggested. The problem consists of these two parts a description of the automaton by a formula suitable for setting up the test and b constructing the test according to the formula. It is assumed that some intermediate inputs and outputs in the automaton take on permanent one or zero values as a result of internal failures in logic cells. Most modern automata consist of standard cells performing the operations of conjunction, disjunction, and negation.
