: It features an advanced Newton-Raphson solver that is significantly faster and more stable than standard SPICE engines.

is a high-performance simulation software suite specifically designed for power electronics engineers. It combines two distinct simulation engines into a single unified design environment. Core Simulation Engines simetrix/simplis

: As a part of or closely related to Simetrix, Simplis seems to be focused on simplifying the simulation process, possibly by offering pre-built models or intuitive interfaces for common system types. This could significantly reduce the time and effort required to set up and run simulations, making it easier for engineers to explore different design options and optimize system performance. : It features an advanced Newton-Raphson solver that

Simetrix and its associated tool, Simplis, are designed to work in conjunction with Simulink, offering extended functionalities for the simulation and analysis of complex systems. While detailed information about these tools might be scarce, their integration with Simulink suggests they are aimed at enhancing the simulation capabilities, possibly in specific domains such as power electronics, control systems, or signal processing. Core Simulation Engines : As a part of

The combination of Simetrix and Simplis with Simulink offers several benefits:

SIMPLIS can find the Periodic Operating Point (POP) of a switching converter than traditional SPICE. A 1ms transient simulation of a PFC boost converter that takes 30 minutes in LTspice runs in ~10 seconds here. This is its killer feature.
