SIMPLIS Technologies is a simulation software vendor focused on the power electronics industry. Its core product, SIMetrix/SIMPLIS, combines the SIMetrix enhanced SPICE environment with the SIMPLIS switching power supply simulation engine, covering workflows such as schematic editing, waveform viewing, transient simulation, periodic operating point (POP), and small-signal AC analysis. The company claims it can be 10-50 times faster than SPICE in power design scenarios. Its positioning is highly specialized: serving teams designing switching power supplies, semiconductors, power systems, and industrial/communications/computing equipment.
The product line includes SIMetrix/SIMPLIS, Pro, and Elite, as well as SIMetrix-only Classic/Pro/Elite editions. Pro/Elite add capabilities such as multi-core support, SystemDesigner, Verilog-A/HDL, and IC-design-related features, with higher-tier versions supporting up to 16 cores. Its add-on modules are fairly targeted: DVM can run batch design verification and generate test reports; MDM is used for inductor and transformer modeling, loss, and thermal analysis; SIMPLIS VH supports Verilog-HDL co-simulation; and custom digital devices can also be implemented through C/C++ DLLs. In terms of ecosystem, SIMetrix Technologies participates in package development and sales, and Altium Designer has also announced support for its power simulation system.
Its commercial versions use per-seat licensing, support portable USB key licenses and LAN/WAN network licenses, and use FlexNET. The website does not disclose specific pricing, so a quote is required. The free SIMetrix/SIMPLIS Elements edition is available for download, with no license or copy restrictions. It is suitable for learning, small designs, and general schematic drawing, but it has circuit-size limitations and lacks capabilities such as command-line operation, Python interfaces, scripting, Verilog-A/HDL, and encrypted models. Prospective customers can usually request a 30-day evaluation license.
Its main strength is deep optimization for switching power supply simulation. POP and AC analysis based on full switching models can reduce the errors introduced by averaged models. Modules such as MDM also show strong coverage of real engineering issues around magnetic components. Documentation resources are fairly complete, including tutorials, training materials, feature matrices, system requirements, and example circuits. The limitations are that platform information mainly points to 64-bit Windows 10/11, while the free edition has clear but fairly restrictive feature boundaries. Advanced features are spread across Pro/Elite editions or add-on modules, and pricing is not visible.
It is suitable for professional power engineers, hardware R&D teams, semiconductor power solution teams, and companies that need to validate switching power supply loops, magnetic component losses, and reliability across multiple operating conditions. It is not a general-purpose development tool for ordinary software developers. The main text does not provide information on access or payment availability from mainland China, so this is considered unknown. If access or procurement is restricted, alternatives such as LTspice, PSpice, PSIM, PLECS, and QSPICE can be evaluated.
