请教vhdl问题 entity dou is
port (
din: in STD_LOGIC;
clk: in STD_LOGIC;
dout: out STD_LOGIC
);
end dou;
architecture dou_arch of dou is
signal x,y:std_logic;
begin
process(clk)
begin
if clk'event and clk='1' then
x <=din;
y <=x;
end if;
dout <=x and (not y);
end process;
end dou_arch;
请问 x <=din;
y <=x;
是并行执行还是顺序执行?
进程内的语句一般是顺序执行的[em06]
但是仿真的结果不对,如果顺序执行,是不是请指教!!不胜感激
同问,怎么达到消抖目的
