[[RF.Spice A/D]] is a powerful simulation environment for analysis and design of analog, digital, RF and mixed-mode circuits. Rather than designing and testing circuits with real physical components in a laboratory with expensive test equipment, [[RF.Spice A/D]] allows you to perform realistic and accurate and realistic simulations of your circuits without clipping wires or splashing solder. With [[RF.Spice A/D]], editing and simulating circuits is a quick, easy, even enjoyable, process.
[[RF.Spice A/D]] consists of a number of tightly integrated tools and utilities that work together seamlessly and provide the ultimate computational power with an intuitive and easy-to-use visual interface. When you start the [[RF.Spice A/D]] application, you are in the '''[[RF.Spice A/D]] Workshop''', with its [[Schematic Editor]] occupying the main window. This is where you assemble your circuit. A circuit is made up of a number of parts like resistors, capacitors, diodes, transistors, voltage and current sources, logic gates, transmission line segments, etc., which are connected to one another using wires. [[RF.Spice A/D]] comes with a very large parts database featuring thousands of passive and active devices including generic models and real parts supplied by major semiconductor device manufacturers. Active device models include no less than six distinct MOSFET models including BSIM3 and BSIM4.
