SystemVue Engines & Simulators
Data Flow Time-Domain Simulation Engine
The SystemVue Data Flow engine provides a scalable time-domain simulation environment for mixed RF and baseband system modeling, enabling efficient development and validation of advanced wireless, radar, satellite, phased-array, and Aerospace & Defense systems. Built on synchronous data-flow technologies, the engine supports realistic simulation of communications DSP, adaptive signal processing, AI-assisted algorithms, and hardware-aware wireless architectures using standards-based and custom waveforms. Extensive libraries of configurable functional blocks simplify development of complex systems through intuitive schematic-based design workflows, allowing engineers to rapidly create and analyze baseband, DSP, modulation, coding, synchronization, beamforming, MIMO, and signal-processing architectures. Integrated support for realistic RF impairments, phased-array effects, propagation channels, and hardware-aware behavioral models enables accurate end-to-end evaluation of modern 5G Advanced, NTN, Wi-Fi, radar, ISAC, and emerging 6G systems under real-world operating conditions.
Products
Advanced RF Analysis Engine
The Spectrasys II RF analysis engine in SystemVue delivers scalable, high-fidelity RF system simulation for advanced wireless, NTN, phased-array, radar, satellite, and Aerospace & Defense applications. Built on a modern modular RF architecture, Spectrasys II supports multidimensional RF modeling through Multi-Independent Parameter (MIP) scheme, enabling accurate representation of RF device behavior across frequency, power, temperature, bias, and operating conditions. The engine combines measurement-driven behavioral modeling, equation-based linear models, and dynamic RF configuration capabilities to accurately simulate nonlinear RF impairments, spectral regrowth, phase noise, leakage paths, active impedance effects, and wideband signal interactions within realistic system environments. Advanced measurement-correlated workflows, including Dynamic Gain Models (DGM) and enhanced mixer modeling, allow engineers to import measured hardware data and reproduce real-world RF behavior with strong correlation to laboratory measurements while significantly accelerating RF architecture exploration and validation.
Phased Array Analysis Platform
The Phased Array Analysis engine in SystemVue enables scalable simulation and optimization of advanced phased-array, massive MIMO, radar, satellite payload, and electronically steered antenna systems within a unified RF digital twin environment. Intelligent phased-array modeling technologies dramatically simplify development of large array architectures by automatically replicating RF signal paths based on splitter and combiner stages, allowing engineers to represent systems containing hundreds or thousands of antenna elements using compact and intuitive schematic structures. The platform supports realistic modeling of phased-array effects including mutual coupling, active impedance interactions, beamforming quantization, calibration errors, nonlinear RF impairments, hybrid beamforming, and adaptive beam steering. Comprehensive analysis and visualization tools provide engineers with advanced capabilities for evaluating 2D and 3D beam patterns, coverage maps, EIRP, sidelobe behavior, beam placement optimization, OTA performance, coexistence, and interference analysis, enabling efficient design and validation of next-generation phased-array systems for 5G Advanced, 6G, radar, EW, and NTN applications.
RF System Design Platform Support
Linux and Windows OS
SystemVue supports both Linux and Windows through a modern cross-platform architecture designed for scalable RF digital twin workflows, collaborative development, and high-performance simulation environments. The platform enables seamless project portability, shared workflows, and consistent simulation behavior across operating systems while supporting GUI-based and headless automation workflows through Python APIs. The redesigned user interface improves usability with enhanced ribbon controls, modern visualization capabilities, workspace portability, and configurable dark and light themes, while preserving compatibility with existing SystemVue projects and libraries. Linux support further enables deployment within enterprise compute environments, cloud infrastructures, and HPC workflows commonly used in Aerospace & Defense, wireless infrastructure, and large-scale phased-array simulation applications.
