使用Virtex6的clocking wizard来使用分频,先元件申明,
component clk_wiz_v3_3
port (
RESET : IN STD_LOGIC;
CLK_IN1_P : IN STD_LOGIC;
CLK_IN1_N : IN STD_LOGIC;
CLK_out1 : out STD_LOGIC
);
END COMPONENT;
然后例化元件,
clk_out : clk_wiz_v3_3
PORT MAP (
RESET => RESET,
CLK_IN1_P => CLK_P,
CLK_IN1_N => CLK_N,
CLK_out1 => CLK10K
);
再在ise core generator中产生ip核,什么都没设置,只设置了差分输入和设置输出频率10M,结果怎么都不对,请大家给我找找原因,谢谢 |
