Online Testing for Three Fault Models in Reversible Circuits

Online Testing for Three Fault Models in Reversible Circuits

 Abstract:

In this paper we propose an approach for the design of online testable reversible circuits. A reversible circuit composed of Toffoli gates can be made online testable by adding two sets of CNOT gates and a single parity line. The performance of the proposed approach for detecting a single bit fault, a cross point fault and the family of missing gate faults has been observed. Discussion around the correctness of our approach and the overhead is also provided.
