* Visualization of the output data
[[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, virtual blocks, 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.
Once your circuit is ready for simulation, [[RF.Spice A/D]] generates a Netlist input and calls its SPICE engine(s). [[RF.Spice A/D]] supports the full Berkeley SPICE 3F5 set of commands, options and models. These include a variety of simulation types such as DC and AC sweeps, transient and Fourier analyses, pole-zero and distortion analyses, network analysis, Monte Carlo and sensitivity analyses, and more. [[RF.Spice A/D]] also provides a large number of black-box blocks including all of XSPICE models such as differentiator, integrator and s-domain transfer function blocks and mutual coupling for transformer modeling. Event-driven [[Digital Simulation|digital simulation]] is fully supported as well as A/D and D/A bridge models for mixed-mode simulation. With a comprehensive library of generic and physical transmission line components and multiport devices, you can perform nodal analysis or network analysis of passive and active RF circuits as well as mixed-signal analog/digital/RF circuits. Black-box virtual blocks allow you to quickly test and verify new system concepts without getting into the nitty gritty of particular circuit realizations.
Using [[RF.Spice A/D]] you can perform live simulations, where output data are generated and animated as the simulation proceeds. You can vary the circuit [[parameters]] in real time during a live simulation. You can also run a large variety of [[tests]] (DC bias, AC, transient, etc.). You can visualize, manipulate and process the output data in the form of graphs or tables in the Data Manager, which is part of the [[RF.Spice A/D]] Workshop.
The [[RF.Spice A/D]] Device Manager is a separate application you can use for defining or importing new parts or modifying those already in the parts bin. You will often find [[RF.Spice]]'s large parts database adequate for most practical circuits. However, you can customize and expand the database to meet your growing analysis and design needs. The Device Manager has an integrated Symbol Editor with an array of drawing tools, which you can use to create new device symbols or modify the existing ones.
