== Product Overview ==Â === RF.Spice A/D in a Nutshell ===
[[RF.Spice A/D]] is a powerful visual simulation environment for analysis and design of analog, digital, RF and mixed-signal circuits and systems. Rather than verifying your circuit designs using real physical components in a laboratory with expensive test equipment, [[RF.Spice A/D]] allows you to perform accurate and realistic simulations of your circuits without clipping wires or splashing solder. With [[RF.Spice A/D]], editing and simulating electronic circuits and systems is a quick, easy, even enjoyable, process.
=== What Can You Do with RF.Spice A/D? ===
Using [[RF.Spice A/D]] you can:
* Build complex systems using a large collection of black-box virtual blocks and perform system-level simulations
* Develop behavioral macromodels of devices, circuits and subsystems, create your own new symbols for them and turn them into new custom parts or blocks and add them to your parts database or share them with others
