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

Automatic Integrated Circuit Modeling Spice

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.

"The goal is a site where the learning of electronics is hands-on and fun. And the SPICE circuit simulator is a great software tool to achieve that goal. It hit me the first time I used SPICE - simulating is fun! And because it's easy to use, I've spent a lot of time building and exploring circuits." - Rick

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?"
