The underlying nature of adiabatic circuits is most accurately characterized at the circuit level as it is for traditional technologies. In order to scale system designs for adiabatic logic technologies, modeling of adiabatic circuits at the logic level is necessary. Logic level models of adiabatic logic circuits can facilitate the design, development, and verification of large scale digital systems that may be infeasible using circuit simulators. Adiabatic logic circuits can be powered with a four stage power clock consisting of idle, charge, hold, and recover stages that provides for adiabatic charging and charge recovery to give adiabatic circuits their low power operation. By both discretizing the temporal aspects of the power clock and the logic values, a logical model of adiabatic circuit operation is proposed. Using the expressive capabilities of Very High Speed Integrated Circuit (VHSIC) Hardware Description Language (VHDL), the salient aspects of adiabatic circuit models can be captured. In this work, a VHDL framework is defined for modeling adiabatic logic circuits & systems and its use is demonstrated in several example adiabatic logic circuits.
