21-- Notes:
22-- This testbench has been automatically generated using types std_logic and
23-- std_logic_vector for the ports of the unit under test. Xilinx recommends
24-- that these types always be used for the top-level I/O of a design in order
25-- to guarantee that the testbench will bind correctly to the post-implementation
26-- simulation model.
27--
28-- based on testbench for FTU_test1
