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 ==
Â
[[B2.Spice A/D]] now has two distinct simulation modes: interactive live "Simulations" and preset non-interactive "[[Tests]]". There are important differences between a Test and a Live Simulation. These differences must be understood before you can effectively use [[B2.Spice A/D]].
Â
A live "Simulation" is simply a continuous transient simulation, starting at time t = 0 and incrementing indefinitely by a user-defined time period. Simulations can be paused and continued but they run continuously until stopped, paused or reset. Simulations can be stimulated by [[Virtual Instruments]] such as Function Generator or Power Supply, can be measured by [[Virtual Instruments]] such as Oscilloscope, Ammeter, Voltmeter, etc. and can be manipulated in real time from the Circuit [[Parameters]] Panel in the Toolbox. Instead of using [[Virtual Instruments|virtual instruments]], you can also use regular voltage or current source devices to excite your circuits or use probes or circuit [[animation]] to display node voltages and currents.
Â
"[[Tests]]", on the other hand, are run with preset and predefined sets of [[parameters]]. [[Tests]] are used to analyze your circuit in various time and frequency domains. These include a circuit's DC bias (operating point), transient and steady-state AC responses, its noise output, network characteristics, as well as various other responses. The results of [[tests]] are displayed on a graph or in a table, not on [[Virtual Instruments|virtual instruments]].
