Ansoft announced the release of Nexxim v3.5 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 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. The product is available on PCs running Microsoft Windows 2000 and XP, Sun Solaris and Linux.
Features of Nexxim v3.5:
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
