Berkeley Design Automation - Analog and RF SPICE (wayback)
(Update - BDA now part of Mentor Graphics)
Analog FastSPICE is based on Precision Circuit Analysis technology. This technology is a proprietary combination of innovative applied mathematics and optimized numerical analysis.
Analog FastSPICE AFS Mentor Graphics
The Analog FastSPICE (AFS) Platform is the world’s fastest nanometer circuit verification platform for analog, RF, mixed-signal, and custom digital circuits.
For silicon-accurate characterization it includes the industry's only comprehensive full-spectrum device noise analysis and a high-productivity Analog Characterization Environment.

Automatic Integrated Circuit Modeling Spice (AIM-Spice) is a version of SPICE, the most popular analog circuit simulator.
AIM-Spice is a new version of SPICE running under the Microsoft Windows and Linux operating systems. AIM-Spice for Windows is capable of displaying graphically the results of a simulation in progress, a feature that allows the operator to terminate a run based on an instant information on intermediate simulation results.
SPICE - The simulator was developed at the University of California, Berkeley, and was first released in 1972. Many scientists at Berkeley and other institutions contributed to the development and improvement in subsequent versions of SPICE.

SPICE is capable of performing both AC (frequency) Analysis and Transient (time) Analysis. SPICE also performs a number of other analyses like DC, Sensitivity, Noise and Distortion.

"At the core of the function generator is a triangle wave generator. How do you generate a triangle wave? The most common way is to get a capacitor and then alternate charging it and discharging it. But how to you get a nice linear ramp across the capacitor?"
