-- Project Name:  SIMULATOR_PULS

-- Target Device:

-- Description:   

-- 

-- VHDL Test Bench Created by ISE for module: FLASH_CONTROLLER

-- 

-- 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.
