EHBSim: Matlab-based multitone excited nonlinear circuit simulation program

This paper presents a nonlinear circuit simulation program called EHBSim implemented in Matlab. This program offers as simulation methods the harmonic balance method, and mainly the nonlinear envelope method. Equations systems that allow the simulation of any circuit architecture were used. The program has original algorithms implemented to solve the associated equation systems. Performance comparison between several simulation methods, through the analysis of multi-excited circuits, is also carried out.
