Key Features

Design Management

• Design management front-end to best-in-class simulation technologies, namely Nexxim® circuit simulation and HFSS™, Q3D Extractor® and SIwave™ for automated parametric electromagnetic co-simulation
• Full hierarchical schematic and layout editors with parameterized scripting (JavaScript® and Visual Basic®) and component callbacks
• Design Validation with scripted Design Rule Checking
• Solver on Demand® provides circuit/system/EM co-simulation with HFSS, Q3D Extractor (including an integrated 2D transmission line simulator) and SIwave. Solver on Demand technology automates generation of ports and simulation setup parameters.
• Ability to "push excitations" representing circuit voltages and currents to the electromagnetic field solvers so that true field values can be calculated while the electromagnetic component is embedded in the circuit
• Integrated post-processing of results including highly customizable rectangular plots, Smith charts, spectral plots, eye diagrams with full eye characteristic measurements, bit-error-rate (BER) contours, and 3D swept parameter plots
• System simulator supports baseband/RF behavioral modeling for defining system architecture, link budgets, circuit specification
• Design optimization, tuning, and swept-parameter analysis
• Statistical, Sensitivity, and yield analyses
• Design utilities include Smith tool matching, transmission line calculator linked to EM simulation
• Standard component library includes behavioral and electrical models and customized vendor design kits
• Ansoft proprietary netlist encryption to protect IP
• Component and model library development/ management UI including P-cell editor
• C++ simulation model generation wizard
• Component reciprocal operations for component de-embedding and calibration wizard for extracting measured data
• SPICE macro-cell netlist import wizard
• IBIS model import wizard
• DXF/GDSII import and export

System/Planar EM Simulation and Design Verification

• 3D planar EM (Method of Moments) provides dynamic parametric co-simulation for direct S-,Y-, and Z -parameter and Full-Wave SPICE™ extraction, near- and far- field radiation analyses.
  • Singular value decomposition technology simulates larger structures with larger numbers of unknowns than other commercial MoM-based tools.
  • Supports open and closed cavity formulations.
  • Self-adaptive triangular meshing provides more accurate simulation results for curved surfaces such as radial bends.
  • Thick metal solver and arbitrary metal orientation provide more accurate simulation of side wall coupling and via-to-via coupling.
  • Advanced excitation port capability (arbitrary feed angle, internal and gap ports).
  • Infinite array analysis and frequency selective surfaces for phased array antenna applications.
  • Queued simulations for parameterized circuits and planar EM.
  • Distributed analysis option for parametric sweeps.
  • Multithreaded, 64-bit solver engine.
• System simulation (time, frequency, and mixed domains) and system test benches apply baseband waveforms to simulate communication metrics, such as ACPR, EVM, BER, and eye diagrams.
  • Extensive RF and DSP component libraries including communication standards, such as IEEE 802.11 a&b, GSM, EDGE, UWB, etc.
  • Compiled and interpretive C and C++ user-defined model co-simulation.
  • MATLAB® co-simulation.
  • WinIQSIM™ links for WCDMA, TD-SCDMA, CDMA2000®, etc., bit and frame accurate waveforms.
