A Q&A with Chris DeMartino
Simulation models are important weapons in the battle for signal integrity. Because semiconductor companies are often less than helpful in offering detailed models, engineers are left to spend time creating their own models or to acquire models from third parties.
We recently asked Chris DeMartino, an applications engineer at Modelithics, to discuss the company’s focus on providing simulation models, primarily for the RF and microwave segments. In this interview, Chris explains the Modelithics business “model” and why the need for good models continues to grow at a rapid pace.
Chris, let’s start with some background. Tell us about Modelithics.
Modelithics has specialized in RF, microwave, and millimeter-wave measurements, and measurement-based, as well as electromagnetic analysis-based modeling of RF and microwave components and semiconductor devices, since 2001. We offer an extensive library collection of models for both passive and active components that are compatible with multiple industry-standard EDA software tools. These libraries include scalable models (known as Modelithics Microwave Global Models) for RLC components, nonlinear models for diodes and transistors, and 3D models for full-wave electromagnetic (EM) simulations, as well as higher level system component models. In terms of measurement capabilities, we have a large repertoire of test-and-measurement equipment that make it possible for the company to measure S-parameters, IV, load pull, noise parameters, ESR, power, load-pull, and non-linear distortion characteristics.
Modelithics has partnered with a variety of EDA companies. How does this all work?
Modelithics has long-standing partnerships with many EDA software companies. Through these partnerships, we provide model “plug-n-plan” libraries for several different EDA software tools. Customers can obtain these libraries, which can be considered an add-on to the software tool itself. We work closely with the EDA companies to ensure the models stay compatible with the latest EDA software versions as well as new model features and capabilities. For example, new library versions are typically released immediately after a new EDA software version is released so that the EDA software companies and mutual customers can use the most recent EDA software versions with our libraries.
