Dynamic timing errors (DTEs), that are caused by the timing violations of sensitized critical timing paths, have emerged as an important threat to the reliability of digital circuits. Existing approaches model the DTEs without considering the impact of input operands on dynamic path sensitization, resulting in loss of accuracy. The diversity of input operands leads to complex path sensitization behaviors,...
Worst-case design is used in IoT devices and high performance data centers to ensure reliability, leading to a power efficiency loss. Recently, approximate computing has been proposed to trade off accuracy for efficiency. In this paper, we use Inexact Speculative Adders, which redesign the adder architecture to shorten its critical path and improve performance, but introduces controlled structural...
