graphical user interface to invoke the Quartus II commands. Doing this tutorial, the students will learn about:

$$ Creating a project

$$ Design entry using VHDL code

$$ Synthesizing a circuit specified in VHDL code

$$ Fitting a synthesized circuit into an Altera FPGA

$$ Simulating the designed circuit

Each logic circuit, or sub$-$circuit, being designed with Quartus II CAD software is called a project. The CAD

software works on one project at a time and keeps all information for that project in a single directory. To begin

a new logic circuit design, the first step is to create a directory to hold its files. We will use a directory introtutorial

to hold the design files for this lab. The example circuit for this tutorial is a simple circuit for two$-$way light

control.

Start the Quartus II software. You should see a display similar to the one in Figure $2.$ This display consists of

several windows that provide access to all the features of Quartus II$,$ which the user selects with the computer

mouse. Most of the commands provided by Quartus II can be accessed by using a set of menus that are located

below the title bar. For example, in Figure $2$ clicking the left mouse button on the menu named File opens the

menu shown in Figure $3.$
