What SIMPLIS Technologies does

SIMPLIS Technologies, Inc. is a privately held US software company headquartered in Portland, Oregon that develops and markets the SIMetrix/SIMPLIS circuit simulation bundle for power electronics engineers. The company's core technology is the SIMPLIS simulation engine, which uses a piecewise-linear (PWL) time-domain simulation methodology combined with Periodic Operating Point (POP) analysis to rapidly converge on steady-state conditions in switched-mode power supply circuits — a capability general-purpose SPICE simulators lack. The platform addresses switched-mode power supply, DC-DC and AC-DC converter, power-factor-correction, digitally controlled power system, and magnetic component design workflows through a tiered product structure (free Elements, paid Pro, top-tier Elite) augmented by add-on modules including SystemDesigner for time-sampled digital control modeling, the Design Verification Module (DVM) for automated converter testing, the Magnetics Design Module (MDM) for physical inductor and transformer design, SIMPLIS VH for Verilog-HDL co-simulation, C/C++ DLL-defined digital devices, and Multi-Core support for parallel Monte Carlo analysis.

The company operates a hybrid go-to-market that pairs product-led growth through a no-registration freemium download with sales-led conversion gated behind login/registration for evaluation and purchase. Direct sales cover North America, while regional distributors handle sales and evaluation support in China, Korea, Taiwan, and Japan. Revenue is generated primarily through annual software subscriptions for Pro and Elite licenses and the various add-on modules, supplemented by paid training (SIMPLIS Essentials online short course and Advanced SIMPLIS Training materials). Pricing is not publicly disclosed. Core technology is protected under US Patent 6,832,182 covering eDVT (electronic Design Verification Technology), and the platform holds ISO 26262 tool classification at TCL1 with TD1 error detection for use in safety-related automotive hardware development. The simulation engine is developed and marketed in partnership with UK-based SIMetrix Technologies Ltd, which provides the underlying simulation environment and GUI.

Customer segments are organized horizontally by use case rather than by vertical: power electronics engineers designing converters and supplies, digital control system designers implementing microcontroller/DSP/FPGA-based control loops, magnetic component designers building inductors and transformers, and automotive electronics engineers working on ISO 26262-compliant designs. The company maintains active customer-facing operations through technical documentation, webinars, training courses, industry conferences (including APEC 2026 in San Antonio, TX), and a continuously updated software release cadence. No venture capital, private equity, or public listing has been disclosed, and no revenue figures are publicly available.

Core offering

SIMPLIS Technologies develops and markets the SIMetrix/SIMPLIS circuit simulation software bundle, purpose-built for switched-mode power supply design. The platform uses piecewise-linear (PWL) simulation with proprietary Periodic Operating Point (POP) analysis for rapid steady-state convergence, and is sold in a free Elements tier plus paid Pro and Elite tiers with optional add-on modules covering digital control, design verification, magnetics design, multi-core parallel simulation, and Verilog-HDL co-simulation.

Product overview

SIMPLIS Technologies offers a platform-plus-modules architecture for power electronics simulation. The core product is the SIMetrix/SIMPLIS software bundle developed in partnership with SIMetrix Technologies Ltd, which combines an integrated environment with the SIMPLIS simulation engine optimized for switched mode power supply design. The product line spans from the free SIMetrix/SIMPLIS Elements (entry-level) through Pro and Elite professional tiers. Add-on modules include SystemDesigner (time-sampled digital control library), DVM (Design Verification Module for automated testing), C/C++ DLL-Defined Digital Devices (custom digital component creation), Multi-Core Support (parallel simulation processing), MDM (Magnetics Design Module for inductor/transformer design), and SIMPLIS VH (Verilog-HDL co-simulation for digital IC verification).

Expansion highlights5 records

Others

• MathWorks: Provides Simulink and Simscape Electrical for system-level and circuit-level simulation, including power electronics. Adjacent rather than direct, as MathWorks focuses on model-based design and system simulation but competes for the same power electronics engineering budget.
• COMSOL: Multiphysics simulation platform with an AC/DC and electrical modules that include switched-mode power supply simulation capabilities. Adjacent competitor that addresses overlapping power electronics use cases through a multiphysics lens.

Broad incumbents

• Synopsys: Leading EDA platform with HSPICE, FineSim, and Custom Compiler for analog and power electronics simulation. Competes with SIMPLIS at the high end of the power electronics design market as part of a comprehensive design platform.
• Ansys: Provides Simplorer (now part of Twin Builder) and other simulation tools targeting power electronics and system-level multiphysics design. Directly comparable in power electronics simulation with much broader multiphysics portfolio.
• Cadence Design Systems: Major EDA platform vendor offering PSpice, Spectre, and other analog/mixed-signal simulators that compete with SIMPLIS in power electronics design workflows. Cadence bundles simulation into a broad platform with vastly greater R&D and sales scale.
• Keysight Technologies: Offers Advanced Design System (ADS) and PathWave tools used in RF and power electronics design. Comparable for power electronics engineers who need EDA workflows integrated with measurement and instrumentation.
• Siemens EDA (formerly Mentor Graphics): Offers Analog FastSPICE (AFS) and other EDA tools serving power electronics and analog IC design. Comparable in the simulation category, with significant advantages in scale, integrated platform offering, and automotive customer relationships.

Regional players

• Empyrean Technology (华大九天): China-based EDA vendor offering analog and mixed-signal simulation tools (e.g., ALPS) and other EDA products. Most relevant in the China market where SIMPLIS relies on a regional distributor and where local EDA substitution is being actively encouraged.

Direct peers

• Analog Devices (LTspice): Distributes LTspice, a free SPICE-based circuit simulator widely used by power electronics engineers for switched-mode power supply design. Most direct substitute in the same user segment, with a free, no-registration distribution model similar to SIMPLIS Elements.

Emerging players

• Qorvo (QSPICE): Qorvo launched QSPICE, a free modern SPICE simulator with a focus on power electronics and mixed-signal design. A newer entrant in the same niche that could pressure SIMPLIS's freemium funnel over time as it matures.
