将整数写入文件vhdl [英] write integer to file vhdl

问题描述

我想在文件(write.txt)上写一个整数(变量num).这是我的代码，但显然不起作用.有什么建议吗?

I would like to write an integer (variable num) on a file (write.txt). Here my code but obviously it does not work. Any suggestion?

library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use IEEE.MATH_REAL.ALL;
library std;
use std.textio.all;

entity file_handle is
end file_handle;

architecture Behavioral of file_handle is

begin

process

variable line_var : line;
file text_var : text;
variable num : integer := 40;

begin        
    file_open(text_var,"C:\Users\Tommy\Desktop\write.txt", write_mode);
    write(line_var, num);         -- write num into line_var
    writeline(text_var, line_var);   -- write line_var into the file
    file_close(text_var);
end process;

end Behavioral;

运行综合后，如果打开write.txt文件，则会读取 b0000000000000000000000000000101000 .似乎是地址或其他内容.我希望读 40 .

After running the synthesis, If I open write.txt file, I read b00000000000000000000000000101000. It seems an address or something else. I expected to read 40.

推荐答案

请尝试使用write(line_var, integer'image(num));.它将把变量num转换为十进制字符串.

Try write(line_var, integer'image(num)); instead. It will convert the variable num to a decimal string.
