Quantum electronic circuits where the logic information is processed and stored in single flux quanta promise efficient computation in a performance/power metric, and thus are of utmost interest as possible replacement or enhancement of CMOS. Several electronic device families leverage superconducting materials and transitions between resistive and superconducting states. Information is coded into bits with deterministic values - as opposed to qubits used in quantum computing. As an example, information can be coded into pulses. Logic gates can be modeled as finite-state machines, that emit logic outputs in response to inputs. The most natural realization of such circuits is through synchronous implementations, where a clock stimulus is transmitted to every logic gate and where logic depth is balanced at every input to achieve full synchrony. Novel superconducting realization families try to go beyond the limitations of synchronous logic with approaches reminiscent of asynchronous design style and leveraging information coding. Moreover, some superconducting families exploit adiabatic operation, in the search for minimizing energy consumption. Design automation for quantum electronic logic families is still in its infancy, but important results have been achieved in terms of automatic balancing and fanout management. The combination of these problems with logic restructuring poses new challenges, as the overall problem is more complex as compared to CMOS and algorithms and tools cannot be just adapted. This presentation will cover recent advancement in design automation for superconducting electronic circuits as well as address future developments in the field.
