Question

问题是输出与 ifs 不匹配。我想要，例如行 A，如果一切都是 1，则输出应该是 11。但它不是

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

游戏包含一个 9 个位置的棋盘，每个玩家在一个免费的房子里移动，并用“0”（玩家 A）或“1”（玩家 B）标记它。

胜利将授予能够在水平、垂直或对角线上放置 3 个“0”或 3 个“1”的玩家。

解决方案应在退出时显示哪个玩家获胜或平局 - 如果没有玩家能够实现定义的目标。

Answer 1

我删除了我原来的答案，因为@pm101 指出它完全偏离了轨道。

编译您的设计后，警告说明了明显的原因：

galo_ports.vhd(142) 处的 VHDL Process Statement 警告：信号 “condition1A”在 Process Statement 中读取，但不在 流程声明的敏感度列表

linA、linB 或 linC 更改时，conditionXXX 信号的值会更新。但是，该过程是同时执行的，并且这些条件信号的值尚未更新。如果您正在模拟设计，您会看到output 的值滞后：它会在输入更改时更新，但它可能会显示之前输入的游戏结果。

修复过程敏感度列表以包含所有条件信号。然后，当您的conditionXXX 信号发生变化并且条件表达式被正确评估时，该过程将被执行。所以像：

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，我会将该条件列表包装到一个带有ELSIF 语句的IF 块中。然后在ELSE 语句中，您还必须定义output 在没有获胜者时的值（或0 是获胜者）：

  --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;
