In the modern VLSI systems, with the technology reaching below 45nm, it is impossible to avoid errors and simultaneously a trade-off between power and speed has become an important design consideration. With huge datasets, this requirement becomes even more stringent. To meet the needs, the systems must be made error-tolerant. In this paper, the authors standardize the error-tolerant adder and compare its performance with the existing adder cells. The given ETA cell is better than other adder cells in terms of power, delay and PDP values.
