报告简介

Advance CMOS technology has made the recent AI and quantum revolution possible, but its growing cost in energy and carbon emissions is untenable. As an adiabatic superconductor logic family, Adiabatic Quantum-Flux-Parametron (AQFP) logic presents a promising avenue for building extremely energy-efficient computing systems. The employment of adiabatic switching operations using AC excitation currents in AQFP logic can substantially diminish the dynamic energy dissipation. Thus, AQFP holds the potential to overcome the power/energy dissipation limitation in conventional superconductor logic families such as rapid-single-flux-quantum (RSFQ). Moreover, AQFP logic offers a powerful logic function presentation ability due to its inherent ability to realize the majority function easily. However, due to its own characteristics, such as the fan-out limitation and clock-synchronized data propagation requirements, circuit design and implementation of AQFP logic become very complicated. Therefore, design automation research is critical for designing these circuits more efficiently. Key challenges include the need to implement complex circuit designs and optimize circuit layouts to minimize energy consumption. Currently, our team has marked some progress in designing and developing EDA tools for AQFP logic, particularly in logic synthesis, placement, and routing, which elevates AQFP logic for practical use.
