B2.Spice A/D Wizards

The idea behind the wizards is easy circuit creation, much in the same way as MS Word has a calendar and résumé creation wizard. Just select the type of circuit that you wish to create, fill in a few choices and the rest of the work is done for you. You can select to place the new circuit directly into your existing circuit or place it in to a new blank circuit to start a design.

For example, power supplies come in many forms with wildly different topologies. Although they appear simple enough, they imply a complex array of design headaches: what transformer winding ratio is needed, what are capacitors’ values, which diodes? Furthermore, using a raw DC power supply with a voltage regulator brings many added calculations, such as drop out voltages. Fortunately, the power supply wizard makes it easy to plop a power supply right into an existing B2.Spice circuit.
