Visual System Simulator™ (VSS) software is an RF and wireless communication systems design environment that allows designers of commercial and military transmitters and receivers to quickly and easily create subsystem architectures and optimize their components for best overall performance.

What's New

  • Radar Systems are increasingly complex and costly to develop. Simulation with comprehensive and detailed RF behavioral models and signal processing as well as with 3D antenna patterns helps to identify design problems before they place further system development at risk. 
  • LTE and NR (5G) Communication Systems and components must address all RF chain impairments in compliance with the 3GPP LTE layer 1 communications standard. VSS provides the models and analysis to address LTE and all current communication standards as well as emerging 5G requirements. 
  • System/Circuit Co-Simulation provides seamless integration with Microwave Office software thereby making it easy to move from system-level design and behavioral modeling to detailed component-level design and verification. 


Design / Simulate / Realize

  • Visual System Simulator - RF and wireless systems design environment for both commercial and military applications. 
  • RFA™  - System-level planning tool to create and verify the initial specifications of a radio design, inclusive of RF budget analysis for RF cascaded measurements and RF inspector to determine the root cause of any intermodulation product.
  • NI AWR Design Environment - Integrates circuit, system, and EM simulation technologies within a comprehensive platform that offers physical layout linked to simulation-ready schematic capture, DRC/LVS, and production-ready GDSII export.
