Description
Keysight RF Circuit Simulation Professional (Nexus) 2026
Nexus 2026 is Keysight‘s professional RF simulation software for designing complex RF and millimeter-wave circuits, 5G/6G components, and RFICs. It introduces workflow-based orchestration with visual whiteboarding and AI‑ready Python automation, running inside ADS, Cadence Virtuoso, and Synopsys Custom Compiler .
Key New Features in 2026
Nexus Connect – Executable Design Whiteboard
Visual flowchart‑based environment replicates the engineer‘s decision process. Users construct workflows on a drag‑and‑drop whiteboard or via auto‑generated Python scripts. Each step executes simulations, optimizations, and design decisions in sequence, supporting decision‑based loops and parameter settings. Workflows automatically generate structured data for AI/ML training and can be shared, reused, and redeployed across teams .
Multi‑Domain Circuit Simulation
Unified simulation algorithms covering multiple domains in one environment:
| Capability | Description |
|---|---|
| SSNA (Small‑Signal & Noise Analysis) | Simulates receivers and amplifiers under large‑signal desensitization or jamming; computes voltage/power gains, SSB/DSB/ASB added noise |
| Transient Analysis | Time‑domain simulation for nonlinear circuits |
| Envelope with IQ Modulation | EVM analysis using I/Q vs. time modulated sources; automatic scaling to given power, voltage, current |
Advanced Optimization Engine
| Feature | Description |
|---|---|
| CMA‑ES Optimizer | Covariant Matrix Adaptation Evolution Strategy for highly nonlinear, noisy RF problems with multiple local optima. Adapts search direction and step size automatically |
| Parallel Optimization | Up to 16× speedup using HPC clusters or token‑based license pools |
| Winslow Nonlinear Stability | Replaces 14 traditional stability analyses; outputs stability margin (not just pass/fail) for risk‑based optimization |
AI‑Ready Python Automation
Full Python API enables programmatic control of simulation and optimization. Supports integration with external AI/ML frameworks (ANNs, LLMs, copilots, AI agents). Python hooks provide deep workflow customization for enterprise methodology deployment .
