-- Project Name:  eval_fixed

-- Description:   
-- 
-- VHDL Test Bench Created by ISE for module: eval_fixed_ja

-- 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.
