FPGA programming using a hardware description language is not a commonly taught skill in physics programs, but is a necessary skill for designing the electronics required for this project.  This tutorial aims to layout the design process and teach the basics of hardware description language; in particular [http://en.wikipedia.org/wiki/Vhdl VHDL].  The main competitor to VHDL is [http://en.wikipedia.org/wiki/Verilog Verilog]; tutorials and information regarding Verilog can be found through Google web searching.

To illustrate the discussions in this tutorial, a design example is discussed along the way.  The design example is the [[Programming_the_FPGA#Emulator_.28D.29|emulator for the AD5535 DAC]].  As each step of the design process is discussed, the DAC emulator will be used for illustration.

Due to the length of the tutorial, it had to be broken into several pages.  Here are the links to the various sections of the tutorial.

Due to the length of the tutorial, it had to be broken into several pages.  Here are the links to the various sections of the tutorial. The first three sections discuss VHDL itself.  The final section is about using the development environment provided by Xilinx; you can read this section first or last as you see fit.
