dff_test.vhd

这是正玹实现代码,通过LUT来实现的!!!比其他要简单的多!还有方波,三角波的不同的VHDL程序实现.

library	ieee;
use ieee.std_logic_1164.all;

entity dff_test is
	port(reset: in STD_LOGIC;
		clk: in STD_LOGIC;
		d: in STD_LOGIC;
		q: out STD_LOGIC
		);
end dff_test;

architecture behav_dff of dff_test is
begin
	s1: process(reset, clk, d)
	begin
		if reset = '1' then
			q <= '0';
		elsif clk'event and clk = '1' then
			q <= d;
		end if;
	end process;
end behav_dff;
