---- Example 1
--  function <function_name>  (signal <signal_name> : in <type_declaration>  ) return <type_declaration> is
--    variable <variable_name>     : <type_declaration>;
--  begin
--    <variable_name> := <signal_name> xor <signal_name>;
--    return <variable_name>; 
--  end <function_name>;

---- Example 2
--  function <function_name>  (signal <signal_name> : in <type_declaration>;
--                         signal <signal_name>   : in <type_declaration>  ) return <type_declaration> is
--  begin
--    if (<signal_name> = '1') then
--      return <signal_name>;
--    else
--      return 'Z';
--    end if;
--  end <function_name>;

---- Procedure Example
--  procedure <procedure_name>  (<type_declaration> <constant_name>  : in <type_declaration>) is
--    
--  begin
--    
--  end <procedure_name>;
