An Algorithm for Pseudo-Exhaustive Test Generation for Combinational Circuits

Pseudo-exhaustive testing is a promising approach for test generation for combinational circuits.This paper proposes an algorithm for pseudo-exhaustive test generation.The algorithm does binary partitioning recur-sively on the circuit to be tested and combines the exhaustive test sets of all the sub-circuits to generate the pseudo-exhaustive test set for the original circuit.It is an application-oriented ad hoc algorithm.It works based on the circuit structure to produce optimal or nearly optimal circuit partitioning and is simple to implement.A machine program implementing the algorithm works satisfactorily and runs fast.The proposed algorithm makes machine generation of pseudo-exhaustive test possible and it is applicable for practical uses.
