-- Create Date: 10:16:32 08/27/2013
-- Design Name:
-- Module Name: C:/Users/Sam/Documents/FPGA/vgaPong/tb_vga.vhd
-- Project Name: vgaPong
-- Target Device:
-- Tool versions:
-- Description:
--
-- VHDL Test Bench Created by ISE for module: vgaPong
--
-- Dependencies:
--
-- Revision:
-- Revision 0.01 - File Created
-- Additional Comments:
--
-- Notes:
-- This testbench has been automatically generated using types std_logic and
-- std_logic_vector for the ports of the unit under test. Xilinx recommends
-- that these types always be used for the top-level I/O of a design in order
-- to guarantee that the testbench will bind correctly to the post-implementation
-- simulation model.
