Ansoft Releases Nexxim v3.5.

New Version Expands Simulation Capabilities of Communication ICs and High-Speed Designs

BOSTON -- Ansoft Corporation (NASDAQ:ANST) announced today the release of Nexxim([R]) v3.5, the latest version of Ansoft's high-performance circuit simulator. Nexxim v3.5 continues its emphasis on simulation speed, capacity and accuracy, while introducing new analyses and Verilog A support, further enhancing the simulation of high-performance electronic design, from signal integrity analysis to high-frequency ICs used in communications systems.

Building upon the software architecture and success of the previous releases, Nexxim v3.5 introduces Oscillator, Circuit Envelope, Periodic Transfer Function, Monte-Carlo and Loadpull analyses to its transient, harmonic balance and noise (time variant and phase) simulation capabilities. Additionally, Nexxim v3.5 natively supports Verilog A, which adds a new dimension of design simulation by enabling system descriptions other than electrical.

"Our latest enhancements to Nexxim are critical to the full characterization of multi-gigabit computer and communication backplanes as well as RFICs," said Dr. Mark Reichelt, director of product development. "The additional analyses, such as oscillator analysis and circuit envelope, address the autonomous source and digitally modulated circuits found specifically in communication ICs, while other capabilities, such as convolution, state-space methods and model caching, provide an efficient method for handling the larger frequency-based models that are finding their way into time-based signal integrity analysis."

New feature highlights of Nexxim v3.5 include:

     -- Oscillator analysis
     -- New circuit envelope analysis for device operation with a
        modulation bandwidth that is orders of magnitude lower than
        the clock frequency
     -- Periodic transfer function analysis
     -- Monte-Carlo analysis available from within the Ansoft
        Designer UI or other established IC design flows
     -- Co-simulation of Harmonic Balance and linear network circuit
        analyses within Ansoft Designer's system-level test bench
     -- Shooting-method
     -- Native Verilog A support
     -- Enhanced state-space model with caching for fast re-simulation
     -- New design utilities
        -- Resonant frequency search for Oscillator designs
        -- Smith tool supports impedance matching; noise, gain and
           stability circle plotting
        -- Loadpull analysis for large signal matching network
           development
     -- Extended noise analysis and post-processing
