This tutorial shows how to use LTspice, which is a powerful, open-source circuit simulator. It starts out by drawing a simple circuit with a voltage source, resistor, LED, and ground. A custom model is made for the LED. Next, a full adder is built at the transistor level using NAND logic gates. The full adder is turned into a symbol so a 4-bit ...
