FPGA and led

This project is intented for people who are new to VHDL.

we will connect a switch and a led to the FPGA and use some VHDL code to toggle the led state each time the switch is pressed.

Some usefull informations:

The main FPGA page [[1]] of the armadeus wiki.

This document [2] gives a lot of usefull informations on how to use ISE Webpack.

Page 9 of this document show the devlight pinout matrix: [3]

Pages 28 and 29 of the APF datasheet show the mapping of the devlight pinouts with the FPGA pinouts :[4]

Schematic

Anatomy of the circuit

The led_top.vhd is a VHDL file where the components of the circuit are instantiated and connected between them.

The functionnal diagram of the file is :*
