The primary innovation of SIMetrix is its hybrid simulation kernel, which combines the standard Berkeley SPICE engine with an exceptionally fast native analog simulator. While many competitors rely solely on SPICE, SIMetrix optimizes the solution process for speed and convergence, particularly for switching circuits like power supplies. This is a critical advantage. Traditional SPICE often struggles with the highly non-linear behavior of switch-mode power supplies (SMPS), leading to long simulation times or convergence failures. SIMetrix overcomes this with its proprietary engine, which uses advanced algorithms to handle discontinuities and stiff systems gracefully. For the power electronics engineer, this means that simulating a full-day cycle of a battery charger or analyzing the loop stability of a DC-DC converter is not a multi-hour wait but a manageable task, accelerating the design cycle from concept to prototype.
SIMetrix utilizes an optimized SPICE-based engine designed to provide rapid results even for complex circuits with thousands of nodes. simetrix
