This tutorial shows the use of the Xilinx ISE tools on three simple design examples: 1) an LED
decoder, 2) a counter which displays its current value on a seven-segment LED and
3) a reprogrammable combination lock. Along the way, you will see:
How to start an FPGA project;
How to target a design to a particular type of FPGA;
How to describe a logic circuit using VHDL, Coregen and/or schematics;
How to detect and fix VHDL syntactical errors;
How to synthesize a netlist from a circuit description;
