Modelithics, a leading provider of high-accuracy RF and microwave active and passive simulation models for Electronic Design Automation (EDA), has released version 25.6 of the Modelithics COMPLETE Library for Keysight Technologies’ Advanced Design System (ADS). This update adds 14 new scalable models representing more than 600 components. It is fully compatible with Keysight ADS 2026 and remains backward compatible with earlier ADS versions.
The Modelithics COMPLETE Library now covers over 29,000 components from 80 manufacturers. Highlights of this release include a new Microwave Global Model™ for an attenuator from International Manufacturing Services (IMS), validated up to 20 GHz and scalable for part values, substrates, and solder-pad dimensions. It also introduces the first of three new varactor-chip models from CapV Micro, validated to 67 GHz and featuring advanced capabilities such as temperature scaling from +25 °C to +85 °C. Additional Microwave Global Models for capacitors, inductors, and resistors are available from Coilcraft, Murata, NIC Components, Passive Plus, and Yageo. All Modelithics models are based on consistent measurement and modeling techniques and include comprehensive documentation, with each model accompanied by a detailed datasheet.
The Modelithics COMPLETE Library for Keysight ADS offers an extensive selection of Microwave Global Models™, representing thousands of components. The installed models are also fully integrated with Cadence AWR electronic design automation (EDA) software. The library includes a substrate library containing measurement-based substrate parameters for many commonly used materials.
Key features include:
- Measurement-Based Development – Each model is created using specialized measurements under device-specific test conditions.
- Scalability – Many models incorporate part-value, substrate, pad-size, and temperature scalability.
- Comprehensive Documentation – Every model is accompanied by a datasheet detailing recommended validity parameters, measurement and test-fixture details, and model-to-measurement data comparisons.
- X-Parameter Models* – An alternative to compact non-linear equivalent-circuit models for transistors, X-Parameter models accelerate non-linear simulations and improve portability between simulation platforms, providing accurate representations of complex integrated circuits for which equivalent-circuit modeling is not practical.
Sub-Libraries
The COMPLETE Library includes several specialized sub-libraries:
- Modelithics CLR Library – All passive components from the COMPLETE Library, including simulation models for a wide range of capacitor, inductor, and resistor families (RLC) from many leading vendors.
- mmWave & 5G Library – Models designed to support next-generation cellular communication standards. All are validated to at least 30 GHz, with some validated up to 125 GHz.
- System Components Library – Models for discrete die, surface-mount, and packaged devices.
- Single-Vendor Sub-Library – All models for a single selected vendor, chosen from more than 75 vendors in the COMPLETE Library.
Through the Modelithics Vendor Partner (MVP) Program, users can access many manufacturer component models—including the new CapV, Coilcraft, and Passive Plus models—free for 90 days.
