Design of Carry Select Adder with Online Testability Using Reversible Gates
P. Sudheer Kumar Reddy, Gaurav Saini · 2019
Now a days, Reversible Logic is winding up increasingly more conspicuous innovation having its applications in different fields like Nanotechnology, Low Power CMOS, Optical Computing. Reversibility plays prominent role for building energy efficient circuits. In this paper, reversible carry select adder is proposed and the performance analysis is verified interms of Ancilla, Quantum Cost and Garbage outputs. Online testing feature is added to reversible carry select adder which detects single stuck-at faults in a circuit. The proposed design is better as compared to basic carry select adder interms of Quantum cost and Ancilla.
