Abstract (in Japanese) (See Japanese page) 
(in English) An adiabatic quantum flux parametron (AQFP) circuit is one of the energy efficient superconducting circuits. To demonstrate large-scale AQFP circuits, we designed and measured 16-bit Kogge-Stone adder. This circuit was designed using an automated placement and routing tool that we developed before. Fabricated chips are composed of about 5000 Josephson junction and are the largest scale circuits using the AQFP circuits. We investigated a method to check the functionality of circuits using input test vectors as small as possible. We have confirmed the partial operation of the circuit and identified the location of the failure based on the measurement results.
