== An Overview of RF.Spice A/D Tests ==

This section describes the details of the various test types available in [[RF.Spice A/D]]. You can specify one or more tests to be performed at the same time. This is done using the checkboxes available for each test type in the "Test Panel" of the Toolbox. Most tests offer three options: Basic, Sweep and Monte Carlo (M.C.). The "Basic" test is a single-run simulation, while in a "Sweep" you vary the value of a device parameter. The "Monte Carlo" simulation provides an opportunity to examine the statistical behavior of your circuit given the tolerances for some part values.

In order to run a successful test, you must set up your circuit and specify the relevant simulation parameters correctly. For example, to run an AC sweep test, or a distortion test or a network analysis, you need to specify one or more AC sources in your circuit. Or if you run a transient test of a circuit with DC sources only, you will get the same response over time unless your circuit is an oscillator. You can access and specify the simulation parameters of each test type by clicking the corresponding "Setup" button to open the respective Test Settings dialog.
The Sweep tab allows sweeping of multiple parameters over the test range. For instance, a resistor’s resistance can be stepped from 1K to 10K, with increments by 1K, over the range of a Transient Test. This will actually run 10 Test runs, with the first run having the resistor’s value at 1K, the second will run with the resistor’s value at 2K, and so on, until the resistor’s value is 10K. You can do multilevel sweeps by specifying more than one parameter to sweep, but care must be used, as this will exponentially increase the number of test runs. The Sweep setup button brings up a box that allows you to specify which parameters and how they are swept. The table format is similar to the Live Circuit panel. Select a parameter to sweep and click the Setup Sweep Parameter to set up the sweep parameters.
The Monte Carlo Test is similar to the Sweep tests, but the parameter values are varied at random, limited to a user-specified range. The Monte Carlo Setup specifies which parameter to vary and how to randomly vary it.
