Question

问题是输出与ifs不匹配。我想举个例子，如果行A的所有内容均为1，则输出应为11，但并非如此。

library ieee;  
 use ieee.std_logic_1164.all;  
 use ieee.numeric_std.all;  

 entity galo_ports is  
  port( LinA : in unsigned(2 downto 0); 
    LinB : in unsigned(2 downto 0);
    LinC : in unsigned(2 downto 0);

    output : out unsigned(1 downto 0)); 
 end galo_ports;

ARCHITECTURE main OF galo_ports IS
SIGNAL values: std_logic_vector(1 downto 0);

SIGNAL condition2A: boolean;
SIGNAL condition3A: boolean;

游戏包含9个位置的棋盘，每个玩家在房子里自由移动，方法是将其标记为“ 0”（玩家A）或“ 1”（玩家B）。

胜利是授予可以水平，垂直或对角放置3个“ 0”或3个“ 1”的玩家的。

如果没有玩家能够达到所定义的目标，则解决方案应在出口处指示哪个玩家获胜或向平局发出信号。

Answer 1

我删除了原来的答案，因为@ pm101指出这完全不正确。

编译设计后，警告指出明显的原因：

galo_ports.vhd（142）上的
VHDL流程声明警告：信号 “ condition1A”在流程语句中读取，但不在流程声明的敏感度列表

当conditionXXX，linA或linB更改时，linC信号的值将更新。但是，该过程同时执行，并且那些条件信号的值尚未更新。如果要模拟设计，您会看到output的值有滞后性：输入更改时会更新，但可能会显示先前输入的游戏结果。

修复过程敏感性列表以包含所有条件信号。然后，当您的conditionXXX信号改变并且条件表达式被正确求值时，将执行该过程。像这样：

PROCESS(condition1A, condition2A, condition3A, condition1B, condition2B, condition3B, condition1C, condition2C, condition3C, condition1COl1, condition2COL1, condition3COL1, condition1COL2, condition2COL2, condition3COL2, condition1COL3, condition2COL3, condition3COL3, condition1DIG1, condition2DIG1, condition3DIG1, condition1DIG2, condition2DIG2, condition3DIG2)

此外，我将用IF语句将该条件列表包装到一个ELSIF块中。然后，在ELSE语句中，还必须定义没有赢家（或0是赢家）时output的值：

  --LINHA 1
  IF condition1A=TRUE and condition2A=TRUE and condition3A=TRUE THEN output <= "11";
  --LINHA 2
  ELSIF (condition1B) and (condition2B) and (condition3B) THEN output <= "11";
  --LINHA 3
  ELSIF condition1C and condition2C and condition3C THEN output <= "11";
  --COLUNA 1
  ELSIF condition1COL1 and condition2COL1 and condition3COL1 THEN output <= "11";
  --COLUNA 2
  ELSIF condition1COL2 and condition2COL2 and condition3COL2 THEN output <= "11";
  --COLUNA 3
  ELSIF condition1COL3 and condition2COL3 and condition3COL3 THEN output <= "11";
  --DIAGONAL 1
  ELSIF condition1DIG1 and condition2DIG1 and condition3DIG1 THEN output <= "11";
  --DIAGONAL 2
  ELSIF condition1DIG2 and condition2DIG2 and condition3DIG2 THEN output <= "11";
  ELSE output <= "00"; -- 0 wins or no winner. 
  END IF;
