ENGLISH ABSTRACT: This thesis presents the design and modernization of Rapid Single Flux Quantum (RSFQ) asynchronous and synchronous logic cells. The asynchronous cells designed are Muller Celement and 3 versions of the Toggle Flip Flop (TFF) which are, the one input and one output TFF, the one input and two output TFF, and another one input and two output TFF but with the outputs that are complementary to one another. The synchronous cells designed are the Delay Flip Flop (DFF) with two complementary outputs, the 2-to-1 digital Multiplexer (MUX) and the 1-to-2 Demultiplexer (DEMUX). The design of these cells follows the RSFQ logic of pulse transfer, storage, and decision-making stages. The purpose of these designs is to integrate them into the available cell libraries particularly the ColdFlux RSFQ cell library so as to expand it to have more logic cells for large-scale circuit designers with less knowledge of RSFQ technology. An example is the use of Muller C-elements in asynchronous timing schemes such as Data Driven Dual Rail and RSFQ asynchronous timing scheme. TFFs are useful for arithmetic logic units and DFFs in shift registers. The MUX and DEMUX are used in some of the microprocessor architectures. The mentioned logical cells are simulated, verified (in terms of timing extraction and critical margins), and optimized using related SPICE engines such as JoSIM, TimEX, Optimum, and JoSIM-Tools. RSFQ electro-techniques will be performed by applying phase-based equations that were derived from Kirchhoff’s laws. The Direct Current (DC) powered superconductor material poses the unique feature of losing all its electrical resistance under certain critical conditions. RSFQ devices being superconductive in nature are a promising candidate to replace semiconductor-rooted technologies. The CMOS technologies are set to reach their limits in the near future as their physical constraints may hinder them from further technological advancements. This gives RSFQ an edge over CMOS in future prospects therefore the need to expand the RSFQ cell library becomes a necessary step in the advances of such field. AFRIKAANSE OPSOMMING: Hierdie tesis bied die ontwerp en modernisering van Rapid Single Flux Quantum (RSFQ) asinkrone en sinkrone logiese selle aan. Die asinkrone selle wat ontwerp is, is die Muller C-element en 3 weergawes van die Toggle Flip Flop (TFF): die een-inset en een-uitset TFF, die een-inset en twee-uitset TFF, en nog ’n een-inset en twee-uitset TFF maar met die uitsette wat komplementˆer tot mekaar is. Die sinkrone selle wat ontwerp is, is die Delay Flip Flop (DFF) met twee komplementˆere uitsette, die 2-tot-1 digitale Multipleksor (MUX) en die 1-tot-2 Demultipleksor (DEMUX). Die ontwerp van hierdie selle volg die RSFQ-logika van pulsoordrag, berging en besluitnemingstadia. Die doel van hierdie ontwerpe is om hulle in die beskikbare selbiblioteke te integreer, veral die ColdFlux RSFQ-selbiblioteek om dit uit te brei om meer logiese selle te hˆe vir grootskaalse stroombaanontwerpers met minder kennis van RSFQ-tegnologie. ’n Voorbeeld is die gebruik van Muller C-elemente in asinkrone tydsberekeningskemas soos Data Driven Dual Rail en RSFQ Asynchronous Timing. TFF’s is nuttig vir rekenkundige logika-eenhede en DFF’s in skuifregisters. Die MUX en DEMUX word in sommige van mikroverwerker-argitekture gebruik. Die logiese selle word gesimuleer, geverifieer (in terme van tydsberekeningonttrekking en kritieke marges), en geoptimeer deur gebruik te maak van verwante SPICE-enjins soos JoSIM, TimEX, Optimum en JoSIM-Tools. RSFQ elektrotegnieke word uitgevoer deur fasegebaseerde vergelykings toe te pas wat van Kirchhoff se wette afgelei is. Die gelykstroom (DC) aangedrewe supergeleier materiaal het die unieke eienskap dat alle elektriese weerstand onder sekere kritieke toestande verdwyn. RSFQ-toestelle wat supergeleidend van aard is, is ’n belowende kandidaat om halfgeleier-gewortelde tegnologie¨e te vervang. Die CMOS-tegnologie¨e sal in die nabye toekoms hul grense bereik, aangesien hul fisiese beperkings hulle van verdere tegnologiese vooruitgang kan verhinder. Dit gee RSFQ ’n voorsprong bo CMOS in toekomstige vooruitsigte, daarom word die behoefte om die RSFQ-selbiblioteek uit te brei ’n noodsaaklike stap in die vooruitgang van so ’n veld.
