Nexxim_White_Paper final for public dislosureNEXXIM Ansoft’s State-of-the-Art Circuit Simulator for RF, Analog and Mixed-Signal Design - White Paper Copyright 2004 Ansoft Corporation I ntroduction Nexxim is Ansoft’s new circuit simulator that provides fast and accurate solutions for tough analog and mixed-signal circuits. It provides the transistor-level simulation accuracy required for sensitive analog and wireless front-end circuits and the capacity to solve the complexities in modern mixed-signal integrated circuits. Transient and harmonic-balance simulations can be performed from a single netlist using the same time-domain device models for broad simulation and analysis of analog and RF circuits. New numerical algorithms and advanced software engineering combine to deliver orders of magnitude improvement in simulation spee……
