Analog circuits are described which are capable of electronically simulating the static and dynamic behavior of superconducting loops containing one or two Josephson junctions when bias currents or magnetic fields are applied. Time-dependent flux entry into or out of the ring can, in either system, be observed by monitoring appropriate node voltages within the simulator circuits. The various dynamical modes observed in earlier numerical simulations are accurately reproduced. A theoretical analysis of the two-junction configuration identifies certain important criteria which determine which of these different states the system will adopt.
