我想模擬我的小程序,我不斷收到錯誤消息,我一直無法弄清楚爲什麼。語法錯誤與進程
錯誤消息是:
line 131 error near process
line 132 error near behavioral ; expected type void
的線條:
130 end if;
131 end process;
132 end Behavioral;
我試圖解決這些幾個小時,我仍然沒有任何線索。
整個代碼:
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;

我認爲你的意思是在tmp = 011和tmp = 100之間。我建議對重新編輯它的問題進行編輯,從而突出顯示缺失的「如果結束」;更清楚。 – 2011-12-30 11:59:43
