Process "Check Syntax" failed

我所有的signal都是用bit或者bit_vector。。。package Mult_Components 里的 signal格式也都检查过没错。。

可是还是出现上面的错误....

下面是主程序code....

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

entity peasant_multiplier is
 port (A, B: in BIT_VECTOR(3 downto 0);
   Start, CLK, Reset: in BIT;
   Result: out BIT_VECTOR(7 downto 0);
   Done: out BIT);
end Peasant_multiplier;

architecture Structure of Peasant_Mutiplier is use work.Mult_Components.All;
 signal ASR, BSR, ADDout, MUXout, REGout: BIT_VECTOR(7 downto 0);
 signal Zero, Init, Shift, Add, Low: BIT := '0'; signal High: BIT := '1';
 signal F, OFL, REGclr: bit;
 

 
begin
 REGclr <= Reset; Result  <= REGout;
 SR1 : ShiftN port map(CLK=>CLK,CLR=>Reset,LOAD=>Init,SH=>Shift,DIR=>Low ,D=>A,Q=>ASR);
 SR2 : ShiftN port map(CLK=>CLK,CLR=>Reset,LOAD=>Init,SH=>Shift,DIR=>High,D=>B,Q=>BSR);
 Z1 : Check port map(X=>ASR,F=>Zero);
 A1 : Adder8  port map(A=>BSR,B=>REGout,Cin=>Low,Cout=>OFL,Sum=>ADDout);
 M1 : Mux8    port map(A=>ADDout,B=>REGout,Sel=>Add,Y=>MUXout);
 R1 : Register8 port map(D=>MUXout,Q=>REGout,Clk=>CLK,Clr=>REGclr);
 F1 : SM1    port map(Start=>Start,CLK=>clk,LSB=>ASR(0),STOP=>Zero,Reset=>RESET,Init=>INIT,Shift=>SHIFT,Add=>ADD,Done=>DONE);
end Structure;

"Start, CLK, Reset: in BIT;
   Result: out BIT_VECTOR(7 downto 0);
   Done: out BIT);"

改为

Start, CLK, Reset: input std_logic;
   Result: output std_logic_vector(7 downto 0);
   Done: output input std_logic);

应该就可以了。

强..可是非要用std_logic呢

难道是因为use IEEE.STD_LOGIC_1164.ALL;
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;

？？？

是的，一般都是用

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

这三个库文件的。
