A Single Electron Device and Circuit Simulator

SIMON is a sophisticated multipurpose simulator for single-electron devices and circuits. It features a graphical circuit editor embedded in a graphical user interface as well as the simulation of co-tunnel events and a single step interactive analyses mode. It supports energy dependent density of states and is able to calculate stability plots.
