ABSTRACT
This paper presents a novel method for accurate
margin calculation of single flux quantum (SFQ) logic cells in
a superconducting electronic circuit. The proposed method can
be utilized as a figure of merit to estimate the robustness of a
logic cell without the need for expensive Monte‐Carlo simulations.
This is achieved through efficient state‐space exploration of all
parameters in the cell structure. Using the proposed approach,
distinct parameter dispersion (DPD) based yield of SFQ cells
increases by 55% on average, compared with state‐of‐the-art
techniques.
