Conference Paper

Asynchronous timing is very important in the design of large-scale ultra-high speed superconducting digital electronic (SDE) circuits. This paper presents an optimized asynchronous self-timing scheme that will simplify and speed up the design of large digital circuits. Rapid Single Flux Quantum Asynchronous Timing (RSFQ-AT) is compared to other timing schemes by implementing, testing and evaluating a variety of circuits. Further it is shown how the design methodology introduced with this asynchronous self-timing scheme can simplify the design of automated CAD tools for RSFQ-AT. © 2005 IEEE.
