PACKAGE P_ALARM IS
        SUBTYPE T_DIGITAL IS INTEGER RANGE 0 TO 9;
        SUBTYPE T_SHORT IS INTEGER RANGE 0 TO 65535;
        TYPE T_CLOCK_tiME IS ARRAY (3 DOWNTO 0) OF T_DIGITAL;
        TYPE T_DISPLAY IS ARRAY (3 DOWNTO 0) OF STD_LOGIC_VECTOR(6 DOWNTO 0);
        TYPE SEG7 IS ARRAY (0 TO 9) OF STD_LOGIC_VECTOR(6 DOWNTO 0);

简易闹钟设计，网上找了很多遇到这个问题的，但是没有解答。package第四行自定义了数据类型，然后在实体里面使用   ENTITY KEY_BUFFER IS
   PORT(KEY : IN  T_DIGITAL;
   CLK : IN  STD_LOGIC;
   RESET :IN  STD_LOGIC;
   NEW_TIME:OUT T_CLOCK_TIME);

编译没有任何问题，但是 的时候，一直提示


Error (10017): Can't create symbol/include/instantiation/component file for entity "KEY_BUFFER" because port "NEW_TIME" are not currently supported by the Quartus II symbol/include/instantiation/component file generator。   意思是quartus不支持这种端口类型？找不到解决的办法啊
