Hi @bahadirozk ,

Because of using use ieee.std_logic_unsigned.all and  use ieee.std_logic_signed.all packages together the issue is coming.

May be there is declaration of some variable or constant in both packages, due to which you are facing this issue, removing any one of the package will resolve the error. Also check this AR link for reference:

You also included std_logic_arith and numeric_std, which both declare signed/unsigned and arithmatic. You should also delete std_logic_arith.

Note: std_logic_unsigned, std_logic_signed and std_logic_arith are all non-standard VHDL packages. Their use is discouraged.
