Nexxim circuit-simulation software for IC design and signal-integrity analysis now works inside the Virtuoso Analog Design Environment package from Cadence Design Systems Ltd. Nexxim bridges the gap between traditional analog Spice and RFcircuit simulation by providing frequency and time-domain solutions for the same circuit (schematic and netlist) using the same device models. The program uses improved algorithms in harmonic balance and transient analyses to get accurate and reliable convergence for sensitive analog blocks.
