product line provides powerful technology for the design of analog and
mixed-signal ICs/ASICs. Featured models include Berkeley's latest BSIM4,
plus MOSFET levels 1-6, EKV MOSFET, BSIMSOI, MESFET and varied-area transistor
devices. Also provided are special injection models derived from Dr. Middlebrook's
legendary General Feedback Theorem for measuring open loop properties
while preserving closed-loop bias conditions. ICAP/4's "IsSpice4"
4th-generation SPICE kernel is vastly enhanced SPICE3F5 and XSPICE based
technology, including several enhancements for large-scale IC/ASIC design.
These include specialized sparce-matrix and look-ahead simulation algorithms,
cutting-edge convergence parameters (some invented by Intusoft), operating
point display on schematic and a gamut of verification analyses such as
Monte Carlo, Worst case and Extreme Value. There are both interactive
(schematic-less) and standard sweeping methods for component parameters,
including real time waveform display for interactive mode.
