Question

I am trying to simulate my small program and I keep getting error messages and I have not been able to figure out why.

The error messages are:

line 131 error near process

line 132 error near behavioral ; expected type void

The lines:

 130    end if;
 131    end process;
 132        end Behavioral;

I have tried to solve these for hours and I still do not have any clue.

Whole code:

use IEEE.STD_LOGIC_1164.ALL;
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;

---- Uncomment the following library declaration if instantiating
---- any Xilinx primitives in this code.
--library UNISIM;
--use UNISIM.VComponents.all;

entity kuutonen is
    Port ( A1 : in  STD_LOGIC;
           B1 : in  STD_LOGIC;
           clk : in  STD_LOGIC;
           A : out  STD_LOGIC;
           B : out  STD_LOGIC;
           C : out  STD_LOGIC;
           D : out  STD_LOGIC;
           E : out  STD_LOGIC;
           F : out  STD_LOGIC;
           G : out  STD_LOGIC);
end kuutonen;

architecture Behavioral of kuutonen is
    signal tmp : std_logic_vector (2 downto 0);

         end if;

            if (tmp ="000") then

Answer 1

Just from inspection, I’d say it’s probably due to a missing “end if;” between the case for tmp=001 and tmp=100.
