library ieee;
use ieee.std_logic_1164.all;
entity startmaker is
port(rst,selt :in std_logic;
start :out std_logic);
end startmaker;
architecture behaver of startmaker is
begin
process
begin
start <= '1';
wait until selt = '1';
start <= '0';
rst_loop:loop
wait until selt = '1';
next rst_loop when (rst = '0');
start <= '1';
end loop rst_loop;
end process;
end behaver;
错误信息是：Error (10398): VHDL Process Statement error at startmaker.vhd(18): Process Statement must contain only one Wait Statement
我看到有些书里面是允许在Process Statement里面有很多Wait Statement，为什么我得quartus II报错呢？ |
