What Modelithics does

Modelithics, Inc. is a privately held provider of measurement-based RF and microwave simulation models for Electronic Design Automation (EDA) tools, founded in 2001 and headquartered in Tampa, Florida. Its core product is the Modelithics COMPLETE Library, a catalog of simulation models for passive components (capacitors, inductors, resistors via the CLR Library), active devices (transistors, diodes), and system-level blocks, distinguished by Microwave Global Models that scale across substrate materials and component part values. Supporting libraries include the mmWave & 5G Library (validated up to 125 GHz), the System Components Library, and the COMPLETE+3D Library for 3D electromagnetic simulation. The company also offers precision characterization and modeling services, including S-parameter measurement up to 170 GHz, noise parameters, load/source-pull, X-Parameter modeling, and GaN HEMT non-linear modeling.

Modelithics monetizes through four revenue streams: software library subscriptions and perpetual licenses (priced quote-based for enterprise, with cloud and named-user options), custom characterization and modeling services, vendor-sponsored free libraries distributed through the 50+ Modelithics Vendor Partner (MVP) program (sponsorship-funded), and legacy test fixtures from the J Micro Technology acquisition. The company's go-to-market combines product-led growth (free SELECT+ Library downloads, university EXEMPLAR program at 120+ institutions, sponsored trials) with enterprise field sales for large accounts and channel partnerships through all major EDA vendors — Keysight, Cadence, Ansys, Sonnet, and MathWorks MATLAB — where Modelithics libraries appear as native model components.

The company serves RF and microwave circuit designers across defense and aerospace (BAE Systems, unnamed US defense contractors), commercial communications (Ericsson, Sirius XM, NXP Semiconductors), academic research (University of Vigo and 120+ universities worldwide), and semiconductor foundries/IDMs. Customers include both enterprise and SMB users, with the MVP program creating a three-sided ecosystem among component vendors (Qorvo, MACOM, Mini-Circuits), EDA platforms, and end-user designers that anchors the company's distribution advantage.

Expansion highlights5 records

Broad incumbents

• Cadence Design Systems: Owner of AWR Design Environment, Spectre RF, and Clarity 3D Solver. Cadence is a Strategic MVP for Modelithics and serves overlapping RF/microwave design customers with AWR Microwave Office; Cadence could expand its native modeling or acquire adjacent modeling technology.
• MathWorks: Owner of MATLAB/Simulink used heavily in RF system design. Modelithics provides a MATLAB-integrated library, but MathWorks offers competing RF Toolbox and SimRF capabilities for system-level simulation.
• Dassault Systèmes (CST Studio Suite): Owner of SIMULIA CST Studio Suite for 3D EM simulation. Modelithics SELECT+ Library is integrated into CST; CST competes directly in full-wave 3D EM simulation where Modelithics 3D EM models also live.
• Synopsys: Largest EDA vendor with growing presence in RF/mixed-signal design (Custom Compiler, PrimeSim). Less directly integrated with Modelithics today, but Synopsys' breadth and M&A history make it a plausible future channel or competitor.
• Keysight Technologies: Owner of the ADS, Genesys, RFPro, and SystemVue EDA platforms. Modelithics models are deeply integrated into Keysight tools, and Keysight is a Strategic MVP — making Keysight both a critical distribution partner and a potential competitor with the resources to develop native measurement-based modeling.
• Ansys: Owner of HFSS and NuHertz for EM and RF simulation. Ansys is a Strategic MVP with Modelithics COMPLETE+3D Library integrated into HFSS, but Ansys' multiphysics and EM simulation platforms compete for the same EDA budget.

Emerging players

• COMSOL: Multiphysics simulation platform with RF and electromagnetics modules that compete for budget at the intersection of EM, thermal, and circuit simulation. Indirectly competitive with Modelithics' 3D EM and electrothermal modeling services.
• Remcom: Provider of XFdtd and Wireless InSite for EM and RF propagation simulation. Remcom overlaps with Modelithics' 3D EM modeling and antenna/system-level RF simulation use cases, though focused more on propagation and antenna placement.
• IMST (empire RF): Specialist in RF/microwave circuit design, EM simulation (Empire XCcel-3D), and custom characterization services. Directly comparable as a smaller specialist offering measurement-based models and design services for RF/microwave customers.

Direct peers

• Sonnet Software: Provider of Sonnet Suites for 3D planar EM simulation. Modelithics CLR Library is integrated into Sonnet for simplified EM co-simulation; both companies serve RF/microwave PCB and IC designers with complementary rather than identical offerings.
