“…The capabilities and advantages of using logic level simulation in the design of large RSFQ circuits was first identified by Krasniewski [19]. From 1992 to 1993 he developed at the University of Rochester a library of RSFQ cells based on Design Works, a standard low-cost semiconductor logic simulator.…”

“…The only implementation specific information included in the model are the values of the timing parameters: the delay, the hold time, the setup time, and the minimum separation time [19], [35], [36]. These parameters can be easily changed without understanding the details of the model.…”

“…To be useful for timing analysis of a large circuit, RSFQ gate models must include information about timing parameters, such as the propagation delay, the hold time, and the setup time [19], [35], [36]. Values of these parameters must be found using circuit (junction) level simulation.…”

“…Beginning in 1993, circuit optimizers (such as MALT [17]) and inductance estimators (such as Lmeter [18]) were introduced to increase the yield of superconducting circuits and accelerate the design process, and the capabilities of circuit simulators and layout editors were significantly enhanced. Also beginning in 1992, research on logic level simulation of RSFQ circuits was initiated [19]. This early research effort led to the development of more efficient tools for simulating RSFQ circuits at the logic level [20].…”

The realization of large integrated circuits depends upon the application of computer-aided design (CAD) tools. This paper summarizes the results of a survey of CAD tools targeting superconducting digital electronics. Five categories of tools: circuit simulators, circuit optimizers, layout tools, inductance estimators, and logic simulators are discussed in detail. Within each category, a comparison of several currently available CAD tools is presented, and a tool which has been adapted for use or developed at the University of Rochester is discussed in greater detail. In addition, tools for timing analysis as well as integrated design environments that permit the effective data interchange among various tools and support libraries of design models are discussed. Future tools for timing optimization, automated logic synthesis, and automated layout synthesis are shown to be necessary for the design of superconducting circuits at the very large scale of integration (VLSI) level of integration. Trends regarding changes in the requirements for effective CAD tools are discussed, and expected improvements to existing tools and features of new tools currently under development are presented.

“…We can refer e.g. to [12], [24], where the basic logical functions have been implemented, and are available as libraries under the standard computer design and simulation environment ( [25], [26]). To complete this basic overview of the RSFQ logic, we list the fundamental logic cells which are frequently used in the RSFQ IC design:…”

The Rapid Single-Flux-Quantum logic (RSFQ) presents an efficient way to achieve ultra fast digital operations. This logic uses the macroscopic effects which can be found in nano-structured superconductor devices such as the Josephson AC and DC effects, and the magnetic flux quantization. As the typical time of the Josephson junction quantized phase leap 2 is in the order of picoseconds, the RSFQ circuits can operate with clock frequencies in the order of hundreds of GHz. This invited paper focuses on basic principles of superconducting RSFQ logic as well as on typical applications, such as the signal conversion or petaflops computing systems. In addition we point out the benefits of the semi-metallic NbN-Ta x N-NbN Josephson junction technology, which has been developed at CEA-INAC inGrenoble.
