Description
Summary:We present Josephson simulator (JoSIM), a simulation program with integrated circuit emphasis (SPICE)-based circuit simulator that utilizes the modified nodal voltage analysis method and trapezoidal integration to solve systems of linear equations. The objective of JoSIM is to provide accurate simulation results with major improvement in terms of simulation speed and expandability. JoSIM incorporates the ability to do phase-based simulation through a modified nodal phase analysis method. A full data visualization GUI, built using open-source graphical libraries, is included. We show the results of simulations with JoSIM and compare them to the results of the JSIM, as well as comparisons between simulation times. We also show extremely large simulations, which are not realizable in reasonable time using JSIM.
