/* Placing Digital Parts */
In this tutorial you will use generic inverter gates and two-input NAND gates to build a three-input AND circuit. You will learn how to define digital inputs and outputs and use RF.Spice's live digital timing diagrams. It is assumed that by this time you have already completed the first few analog tutorial lessons and are comfortable with navigating the [[RF.Spice A/D]] Workshop.
== Placing the Digital Parts ==
To build your first digital circuit, you need the following parts:
