The Next-Generation of Circuit Simulation in RF EDA White Paper

Keysight is reimagining RF simulation as a programmatically controlled, extensible platform—an approach that integrates tightly with measurement science, leverages automation, and opens the door to Artificial Intelligence (AI). This whitepaper explores the limitations of traditional RF simulators and why a new architecture is needed for developing a next-generation RF simulation engine. See the immediate productivity benefits from Python integration, troubleshooting aids, and parallel optimization. These benefits yield immediate possibilities for automated workflows, no-code design sequencing, and AI-driven exploration.

An Executable RF Design Workflow Whiteboard

Nexus Connect captures the complete design methodology, immediately deploys it in customized workflows with simulation and optimization, and visually documents each workflow. Work visually on an executable whiteboard flowchart or programmatically in Python. Read this Solution Brief to get started.

RF Circuit Simulation Professional Webinar

Join Cedric Pujol, RF simulation R&D manager from Keysight EDA, to learn how Keysight’s new RF Circuit Simulation Professional (Nexus) makes it possible to streamline multi-technology integration, simulation, and optimization by revamping the RF circuit design workflow.

This educational webinar shows how the next generation of AI–ready RF circuit simulation and optimization workflow can be efficiently and cost-effectively deployed to achieve an unprecedented increase in design productivity and eliminate wasteful tape-out respins.

Workflow-Based User Interface (UI)

RF Circuit Simulation Professional UI organizes simulation and optimization control as workflows instead of disjointed tasks to closely capture the designer’s thought process in producing a design.

The RF Circuit Simulation Professional UI and workflows work identically in the industry’s most trusted EDA platforms: Keysight Advanced Design System (ADS), Cadence Virtuoso, and Synopsys Custom Compiler.

Multi-Domain RF Circuit Simulation Technologies

The RF Circuit Simulation Professional multiple circuit simulation algorithms operate across multiple domains (frequency, envelope-transient, linear, nonlinear, stability, electrothermal, system and measurement) for thorough characterization to satisfy multi-spec design requirements.

Multi-domain simulations can be customized (e.g., multi-dimensional sweeps), sequenced and saved as workflows to ensure all required performance specs are consistently analyzed thoroughly.

Multi-Domain RF Circuit Simulation Technologies

Multi-Performance Parallel Optimization Algorithms

Optimize RFIC designed in Virtuoso or Custom Compiler together with off-chip 3DHI packaging and integration inside Keysight ADS. Unlike traditional circuit optimizers, advanced RF Circuit Simulation Professional optimization algorithms operate on challenging designs with large-scale variable counts, such as RFICs and 3DHI transceiver modules.

External Python-based optimization algorithms can also be used in RF Circuit Simulation Professional to supplement the already powerful native optimizers.

AI-Ready with Python Automation

The RF Circuit Simulation Professional Python application programming interface (API) enables programmatic control of simulation and optimization to automate workflows and to interact with external AI and Machine Learning (ML) frameworks to exploit the power of AI assisted designs.

Python automation makes RF Circuit Simulation Professional AI-ready to leverage machine learning models such as artificial neural networks (ANN) and large language models (LLM), and enables integration with external AI algorithms and frameworks, such as copilots and AI agents, to realize unprecedented productivity.
