Cadence Allegro AMS Simulator
Cadence Allegro AMS Simulator is the industry standard for analog and mixed signal simulation, it allows you to simulate everything from high-frequency systems to low-power IC designs.

Cadence® Allegro® AMS Simulator contains PSpice®technology at its core to provide fast and accurate simulations for analog and mixed-signal designs. This Advanced Analysis package includes utilities for sensitivity analysis, goal-based multi-parameter optimization, component stress and reliability analysis, and Monte Carlo analysis for yield estimation. Allegro AMS Simulator is a unified environment for taking designs further—improving time-to-market performance and the overall quality of your design while keeping operating costs in check.

When combined with Allegro Design Entry HDL, the schematics drawn in AMS Simulator can also drive PCB layout, significantly reducing design time and eliminating redrawing errors. It fully explores the relationships in your design with "what if" scenarios before committing to final implementation. AMS Simulation includes a large library of known models and behavioral modeling techniques that make refining the analog/digital interface a straightforward task.
