“…While in the past, a pure reversible scheme has been assumed (see e.g. [15,16]), findings recently summarized in [6] showed that conditional reversibility is actually sufficient for adiabatic circuits. Again, this is illustrated by means of an example:…”

“…While previously considered circuits were either handcra ed (following approaches e.g. proposed in [2,17]) or relied on fully reversible realizations which led to an unnecessarily large overhead (as conducted in [15,16] and discussed in [6]), the proposed design flow allows for generating the desired adiabatic circuits in an automatic fashion while, at the same time, satisfying the switching rules by conditional reversibility only. e improvements obtained by the advanced schemes additionally show the further potential that can be exploited following this direction.…”

Adiabatic circuits are heavily investigated since they allow for computations with an asymptotically close to zero energy dissipation per operation-serving as an alternative technology for many scenarios where energy efficiency is preferred over fast execution. eir concepts are motivated by the fact that the information lost from conventional circuits results in an entropy increase which causes energy dissipation. To overcome this issue, computations are performed in a (conditionally) reversible fashion which, additionally, have to satisfy switching rules that are different from conventional circuitry-crying out for dedicated design automation solutions. While previous approaches either focus on their electrical realization (resulting in small, hand-cra ed circuits only) or on designing fully reversible building blocks (an unnecessary overhead), this work aims for providing an automatic and dedicated design scheme that explicitly takes the recent findings in this domain into account. To this end, we review the theoretical and technical background of adiabatic circuits and present automated methods that dedicatedly realize the desired function as an adiabatic circuit. e resulting methods are further optimized-leading to an automatic and efficient design automation for this promising technology. Evaluations confirm the benefits and applicability of the proposed solution.
