Visual System Simulator

January 17, 2011

VSS-2010AWR Corporation, the innovation leader in high-frequency EDA, released its Visual System Simulator™ (VSS) software.

The release offers new capabilities that increase productivity for RF system designers; including time delay neural network (TDNN™) advanced amplifier behavioral models for capturing memory effects and measurement data interchange format (MDIF) model support, as well as a new phased array element for radar design engineers. Additionally, enhancements have been made to the VSS RFA™ architect tool plus new communication models and signal processing blocks have been added.

Key Features in VSS 2010:

TDNN* ( time delay neural network) based models:

  • New circuit-based nonlinear behavioral model for VSS that can capture memory effects in power amplifiers

Turbo decoders:

  • Support for turbo codes used in 3G/4G standards such as cdma2000, IS856, WiMAX, and LTE
  • Library/components that can be used for decoding of custom turbo codes

Third party integrations:

  • AWR Connected™ for R&S WinIQSIM2 waveform generation software. Support for all standards and variants within VSS, including export to R&S K96 for OFDM standards analysis
  • MATLAB® co-simulation
