The [[RF.Spice A/D]] application comes with a node-locked license that works only on the computer for which it was originally generated. After you install [[RF.Spice A/D]] on your computer and try to start the program for the first time, it pops up an error message saying it could not locate the license file. This message also displays one or more MAC Addresses specific to the computer on which you have installed the [[RF.Spice A/D]] application. A MAC address is a 12-character string that is a combination of letters and numbers. You need to email this MAC address to us so we can generate a license file for you. Once you receive the ".LIC" license file from us, place it in the "Licenses" folder of your [[installation]] directory. You are now set to go!
== Two Distinct Simulation Modes ==
In [[RF.Spice A/D]] provides , you can choose two distinct simulation modes: interactive "Live Simulations" and non-interactive "Predefined [[Tests]]". There are important differences between a test and a live simulation that must be understood before you can use [[RF.Spice A/D]] effectively.
A "Live Simulation" is simply a continuous transient simulation, which starts at time t = 0 and increments indefinitely by a user-defined time step. Simulations can be paused and continued but they run continuously until they are stopped, paused or reset. Live simulations can be stimulated by [[Virtual Instruments|virtual instruments]] like a Function Generator or Power Supply, and their results can be measured by [[Virtual Instruments|virtual instruments]] like the Oscilloscope, Ammeter, Voltmeter, etc. You can also use regular voltage or current sources to excite your circuit during a live simulation or use probes or circuit [[animation]] to display node voltages and currents in real time. You can vary your circuit's parameter values in real time from the "Circuit [[Parameters]]" panel of the toolbox and observe the circuit's response immediately.
"Predefined [[Tests]]", on the other hand, are run with some advance planning and preset simulation [[parameters]]. You can run [[tests]] to analyze your circuit in time and frequency domains and characterize its DC bias (operating point), transient and steady-state AC responses, noise performance, network [[parameters]], etc. The output results of [[RF.Spice A/D]] [[tests]] are displayed on graphs or tabulated in tables.

== Two Simulation Engines ==
Â
[[RF.Spice A/D]] has two distinct and independent simulation engines: the mixed-mode simulator and the event-driven digital simulator. Each of these two simulators has its own schematic mode. The mixed-mode simulator simulates analog, RF and mixed analog/digital circuits. If your circuit is pure analog or RF or contains both analog and digital parts, then the mixed-mode schematic and simulator are used. If your circuit is pure digital, then the digital schematic and simulator are evoked, which allow for interactive inputs and outputs. The selection of the appropriate schematic mode and simulation engine is done automatically by [[RF.Spice A/D]]. In other words, you don't have to specify the type of your circuit or choose a particular simulation engine type.
