VHDL 波形中的字符串

Question

如何打印 VHDL 波形中的字符串？ -> like here

Answer 1

字符串与其他类型的信号没有什么不同，所以你可以这样做：

library ieee;
use ieee.std_logic_1164.all;

entity tb is
end entity;

architecture sim of tb is

  signal info : string(1 to 5);

begin

  process is
  begin
    info <= "Hello";
    wait for 1 us;
    info <= "VHDL ";
    wait for 1 us;
    info <= "world";
    wait for 1 us;
    info <= "!!!  ";
    wait for 1 us;
    wait;
  end process;

end architecture;
