Often bundled together, SIMetrix/SIMPLIS combines the standard SPICE simulator with SIMPLIS (SIMulation of Piecewise Linear Systems). While SIMetrix handles general analog design, SIMPLIS is specifically optimized for switching power supplies, offering speeds up to 10 to 50 times faster than standard SPICE for these applications.

SIMPLIS simulator for power electronics. It functions as a high-performance standard SPICE solver similar to PSpice or LTSpice, but optimized for speed and convergence in complex industrial applications.

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

The software is distinguished by several key technical features that streamline the circuit design process:

One of Simetrix's defining characteristics is its dual-engine approach. It integrates two distinct simulators into a single environment: It functions as a high-performance standard SPICE solver

Simetrix is the flagship simulation product of , a company founded by engineers with deep expertise in power electronics and analog simulation. The software was specifically developed to address the limitations of traditional SPICE (Simulation Program with Integrated Circuit Emphasis) simulators, particularly when dealing with switching power supplies and complex analog systems.

One of the most significant advantages cited by users is its ability to converge on solutions for difficult non-linear circuits where other SPICE simulators might fail. SIMPLIS Integration: Often bundled together

Simetrix represents a bridge between traditional analog simulation and the high-speed requirements of modern power electronics. By combining a robust SPICE engine with the proprietary SIMPLIS technology, it provides engineers with a versatile toolkit that accelerates the design cycle and improves the reliability of electronic products. Whether designing a simple audio amplifier or a complex multi-phase power converter, Simetrix remains a trusted tool in the engineer’s arsenal.
