For loop Verilog:转换的整数不适用于for循环

我正在用Verilog编写一个程序，它接受一个二进制值，将其转换为整数，然后打印“Hello，World！”这样的次数

但是，每当我运行程序时，都不会显示Hello，World。代码如下：

// Internal Variable
wire [0:4] two_times_rotate;

// Multiply the rotate_imm by two (left shift)
assign {two_times_rotate} = rotate_imm << 1;
integer i, times_rotated;

// Convert two_times_rotate into an integer
always @( two_times_rotate )
begin
  times_rotated = two_times_rotate;
end

initial 
begin

for (i = 0; i < times_rotated; i = i + 1)
begin
  $display("Hello, World");
end

end

assign {out} = in;
 endmodule

//内部变量
导线[0:4]旋转两次；
//将rotate_imm乘以2（左移）
赋值{two_times_rotate}=rotate_imm
times_rotated
在计算for循环时的时间0为
32'bX
。for循环正在检查
i<32'bX
，这是错误的


根据您的更新，这可能是您的意图：

module immShifter( input [31:0] in, input [3:0] rotate_imm, output [31:0] out );
  integer i, times_rotated;
  always @*
  begin
    times_rotated = rotate_imm << 1;
    for (i = 0; i < times_rotated; i++)
      $display("Hello, World");
    $display(""); // empty line as separate between changes to rotate_imm
  end
  assign out = in;
endmodule

模块immshift（输入[31:0]输入，输入[3:0]旋转\u imm，输出[31:0]输出）；
整数i，乘以_旋转；
总是@*
开始
times\u rotated=rotate\u imm看起来代码的前几行是missing@jean28，我建议不要将
assign
放在
始终
块或
初始
块中。大多数设计人员声明压缩数组采用（小端）[格式（即
[31:0]
）.那么我如何将其转换为整数，以便它检查正确的条件？@jean28，您希望正确的条件是什么？此时，所有内容都在时间0处运行。所有内容都在Verilog中并行运行，因此执行顺序取决于模拟器调度程序的突发奇想。
 module immShifter(input[0:31] in, input[0:3] rotate_imm, 
              output[0:31] out);

 // Internal Variable
 wire [0:4] two_times_rotate;
 reg [0:4] i;

 // Multiply the rotate_imm by two (left shift)
 assign {two_times_rotate} = rotate_imm << 1;
 integer times_rotated, for_var;

 // Convert two_times_rotate into an integer
 always @( two_times_rotate )
 begin
    assign{times_rotated} = two_times_rotate;
 end

 initial 
 begin

 assign{i} = 5'b00000;
 assign{for_var} = times_rotated;
 for (i = 5'b00000; i < times_rotated; i = i + 5'b00001)
 begin
   $display("Hello, World");
 end

 end

 assign {out} = in;
endmodule 

module immShifter( input [31:0] in, input [3:0] rotate_imm, output [31:0] out );
  integer i, times_rotated;
  always @*
  begin
    times_rotated = rotate_imm << 1;
    for (i = 0; i < times_rotated; i++)
      $display("Hello, World");
    $display(""); // empty line as separate between changes to rotate_imm
  end
  assign out = in;
endmodule
