Why Use RF Circuit Simulation Professional (Nexus)
AI-ready RF-MW-mmWave circuit simulation and optimization.
RF Circuit Simulation Professional is the industry’s state-of-the-art AI-ready RF circuit simulation and optimization technology. It enables you to design the most challenging RF-MW-mmWave circuits, RFICs, and 3D Heterogeneous Integrated (3DHI) RF transceiver modules for 5G/6G, wireless networking, radar, and aerospace-defense applications.
Keysight’s RF Circuit Simulation Professional enables RFIC designers to perform parallel multi-domain, multi-physics analyses efficiently in the ADS, Cadence Virtuoso or Synopsys Custom Compiler workflow. AI-assisted parallel optimization algorithms refine on-chip RFIC together with off-chip packaging to achieve multi-objective performance and the highest yield.
Its unique Nexus Connect capability captures complex RFIC design workflows that include simulation, optimization, decision trees and parameter settings, as executable flowcharts. These Python based flowcharts are self-documenting for design reviews and can be reused by you or AI-agents to orchestrate complex pre-tapeout verification.
