Hi monkeyboy:

I don't see straight the examples you offered , can you give me the appropriate format of the examples.

and now I found a new problem about the ad16bit core, that is:

if I change the width of "Port Q " from 16 to 32 , then when I build the soft project , the builing is failed because the size of the ad16bit is too large. and I found that when I fix

"Q : out STD_LOGIC_VECTOR(15 DOWNTO 0));" the size of the ad16bit range from 0x0xxxxx0 to 0xxxxx7 ,but when I fix "Q : out STD_LOGIC_VECTOR(31 DOWNTO 0)); " and the size of the ad16bit range from 0x0xxxxx0 to 0xxxxxF , what's wrong with the problem and how can I slove it ?!!
