我是个学eda的新手，写好代码后语法检查，出现parse error, unexpected ELSIF, expecting END错误，求解答

entity alarm_controller is
Port ( key : in STD_LOGIC;
clk : in STD_LOGIC;
reset : in STD_LOGIC;
time_button : in STD_LOGIC;
alarm_button : in STD_LOGIC;
load_new_c : out STD_LOGIC;
load_new_a : out STD_LOGIC;
show_new_time : out STD_LOGIC;
show_a : out STD_LOGIC);
end alarm_controller;

ARCHITECTURE ART OF ALARM_CONTROLLER IS
TYPE t_state IS (S0, S1, S2, S3,S4);
CONSTANT KEY_TIMEOUT :std_logic_vector := "11101";
SIGNAL CURR_STATE : t_state;
SIGNAL NEXT_STATE : t_state;
SIGNAL COUNTER :std_logic_vector(4 downto 0);
SIGNAL ENABLE_COUNT : STD_LOGIC;
SIGNAL COUNT_END : STD_LOGIC ;
BEGIN
PROCESS(CLK,RESET)
BEGIN
IF RESET ='1' THEN
CURR_STATE <= S0;
ELSE
IF rising_edge(clk) THEN
CURR_STATE <= NEXT_STATE;
END IF;
END IF;
END PROCESS;

……没有代码怎么说。只能看出来，你乱用了elsif 和没有end if。

支持一下感觉挺不错的
