Design of Approximate Circuits by Fabrication of False Timing Paths: The Carry Cut-Back Adder

Christian Enz, Vincent Frédéric Camus, Jérémy Lucien Maurice Schlachter, Mattia Cacciotti

This paper introduces a novel method for designing approximate circuits by fabricating and exploiting false timing paths, i.e. critical paths that cannot be logically activated. This allows to strongly relax timing constraints while guaranteeing minimal an ...
