在VHDL元程序设计中强制将字符串作为集合的成员

library ieee;
use ieee.std_logic_1164.all;
use ieee.std_logic_textio.all;

entity string_to_set is
end entity;

architecture behavioral of string_to_set is
  signal my_set : std_logic_vector(0 to 7);
  signal my_string : string := "Hello";

begin
  process
  begin
    my_set <= std_logic_vector(to_unsigned(0, my_set'length)); -- 初始化集合

    -- 将字符串转换为集合的成员
    for i in my_string'range loop
      if my_string(i) in my_set then
        report "String element already in set";
      else
        my_set(i) <= '1';
      end if;
    end loop;

    -- 打印集合中的成员
    for i in my_set'range loop
      if my_set(i) = '1' then
        report "Set member: " & integer'image(i);
      end if;
    end loop;

    wait;
  end process;

end architecture;
