What SIMPLIS Technologies does

SIMPLIS Technologies, Inc. is a privately held, founder-owned US software company headquartered in Portland, Oregon that develops and markets simulation software specialized for switched-mode power supply design. Its core technology is SIMPLIS, a piecewise-linear time-domain simulation engine purpose-built for the topology transitions that occur in switching power converters, distinguishing it from general-purpose SPICE simulators through faster convergence to steady-state via Periodic Operating Point (POP) analysis and accurate handling of switching events. The flagship product is the SIMetrix/SIMPLIS bundle, jointly developed with UK-based SIMetrix Technologies Ltd, combining the SIMPLIS power-electronics engine with SIMetrix's enhanced SPICE analog/mixed-signal simulator within a unified schematic and waveform environment. The platform is extended by addon modules — DVM (Design Verification Module, protected by US Patent 6,832,182), SystemDesigner for time-sampled digital control, Magnetics Design Module (MDM), SIMPLIS VH for Verilog-HDL co-simulation, Multi-Core Support, and C-Code DLL — and is also classified for ISO 26262 automotive functional-safety workflows.

The company serves power-electronics engineers and engineering organizations across multiple verticals, including power supply manufacturers, semiconductor design companies, system designers, computing and telecommunications equipment OEMs, industrial motor and energy conversion markets, and (via ISO 26262 qualification) automotive hardware design teams. SIMPLIS Technologies generates revenue primarily through time-limited and permanent software licenses (FlexNet-based, node-locked) sold via direct enterprise sales and a global distributor network covering the United States, China, South Korea, Taiwan, and Japan. A free-tier product, SIMetrix/SIMPLIS Elements, drives top-of-funnel user acquisition, with conversion to paid professional licenses for unrestricted circuit sizes and advanced modules. The company also offers online training (SIMPLIS Essentials) and professional services, and participates in industry events such as APEC for lead generation. It is co-founded and controlled by Tom Wilson and Ron Wong, the original developers of the SIMPLIS algorithm from the late 1980s.

Core offering

SIMPLIS Technologies develops and licenses the SIMetrix/SIMPLIS simulation software bundle for power electronics design. The product combines the SIMetrix enhanced SPICE analog/mixed-signal simulator with the SIMPLIS piecewise linear simulation engine, which is purpose-built for switched mode power supply (SMPS) design, including DC-DC converters, AC-DC converters, PFC stages, and resonant converters. Addon modules such as DVM, SystemDesigner, MDM, SIMPLIS VH, Multi-Core, and C-Code DLL extend the platform with design verification, digital control modeling, magnetics design, Verilog co-simulation, parallel processing, and custom device support.

Product overview

SIMPLIS Technologies offers a platform-plus-modules product architecture centered on SIMetrix/SIMPLIS, a comprehensive simulation software bundle combining SIMetrix (enhanced SPICE-based analog/mixed-signal simulator) with SIMPLIS (specialized piecewise-linear simulation engine for switched mode power supply design). The core bundle is complemented by specialized addon modules: DVM (Design Verification Module) for automated testing, SystemDesigner for time-sampled digital control modeling, MDM (Magnetics Design Module) for magnetic component design, SIMPLIS VH for Verilog-HDL co-simulation, Multi-Core Support for parallel processing, and C-Code DLL for custom digital device creation. A free tier is available via SIMetrix/SIMPLIS Elements, a limited demonstration version. SIMetrix Classic is offered as a standalone general-purpose SPICE simulator. Training is provided through online self-paced courses.

Direct peers

• Plexim (PLECS): Plexim offers PLECS, a circuit and system-level simulator specifically built for power electronics, including switched-mode power supplies, motor drives, and renewable energy converters — directly competing with SIMPLIS's PWL approach and POP analysis in the same niche of power-electronics design engineers.
• Powersim (PSIM): Powersim's PSIM is a specialist power-electronics and motor-drive simulator widely used for switched-mode power supply and converter design; it targets the same engineering audience as SIMPLIS and competes on similar POP, AC, and transient analysis capabilities.
• Altair (PSIM acquired): Altair acquired Powersim and now markets PSIM as part of its simulation suite; it is a direct competitor for power-electronics simulation and brings broader enterprise-platform distribution and bundling that SIMPLIS lacks.

Broad incumbents

• Synopsys: Synopsys Saber is a long-standing power-electronics and electrical-system simulator, and the broader Synopsys EDA portfolio competes for the same power-design engineering budgets that SIMPLIS targets.
• MathWorks: MathWorks' Simulink and Simscape Electrical enable system-level power-electronics simulation and compete with SIMPLIS for system-design and control-loop modeling use cases among larger engineering organizations.
• Cadence Design Systems: Cadence's PSpice, Spectre, and Spectre APS simulators serve power-electronics and analog design. Cadence is a broad EDA incumbent that competes with SIMPLIS by bundling power simulation into larger PCB and IC design flows.
• Keysight Technologies: Keysight's ADS, SystemVue, and EMPro provide electronic-system simulation across RF, signal integrity, and power, competing for parts of SIMPLIS's customer base in computing/telecom power design.
• ANSYS: ANSYS offers Twin Builder, Maxwell, and Simplorer for power-electronics and system-level simulation. While broader in scope, ANSYS competes with SIMPLIS at large accounts that prefer end-to-end multiphysics suites over single-purpose tools.

Emerging players

• Analog Devices (LTspice): LTspice is a free, widely adopted SPICE-based simulator that handles power-converter design for a broad set of engineers; while not specialized for PWL/POP analysis, it competes at the entry level and shapes the price expectations of power-electronics designers evaluating tools like SIMPLIS.

Others

• SIMetrix Technologies Ltd: SIMetrix Technologies is SIMPLIS Technologies' long-standing UK partner that develops the SIMetrix SPICE engine and the integrated schematic/waveform environment of the SIMetrix/SIMPLIS bundle; they are adjacent ecosystem collaborators rather than direct competitors.
