CrossSim is a crossbar simulator designed to model resistive memory crossbars for both neuromorphic computing and (in a future release) digital memories.  It provides a clean python API so that different algorithms can be built upon crossbars while modeling realistic device properties and variability.  The crossbar can be modeled using multiple fast approximate numerical models including both analytic noise models as well as experimentally derived lookup tables. A slower, but more accurate circuit simulation of the devices using the parallel spice simulator Xyce is also being developed and will be included in a future release.
