-- 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.
