-- btn_debounce.vhd -- Button Debouncer
----------------------------------------------------------------------------
-- Author: Sam Bobrowicz
-- Copyright 2011 Digilent, Inc.
----------------------------------------------------------------------------
--
----------------------------------------------------------------------------
-- This component is used to debounce signals generated by external push
-- buttons. It is designed to independently debounce 5 Push button signals.
-- Debouncing is done by only registering a change in a button state if
-- it remains constant for 2^16 clock cycles.
--
-- Port Descriptions:
--
-- BTN_I - The input button signals
-- CLK - Behavior is optimized for a 100 MHz clock
-- BTN_O - The debounced button signals
