1# 梦境缠绕
俺玩过SPARNT-6的DNA，如下：
先做一个库声明
library UNISIM;
use UNISIM.vcomponents.DNA_PORT;
然后调用DNA_PORT即可
DNA_PORT_inst : DNA_PORT
generic map (
SIM_DNA_VALUE => X"000000000000000" -- Specifies the Pre-programmed factory ID value
)
port map (
DOUT => DNA_PORT_dout,
CLK => device_DNA_clk_bufg,
DIN => DNA_PORT_din,
READ => DNA_PORT_read,
SHIFT => DNA_PORT_shift
);
需要特别注意的是DNA_PORT的CLK频率很低，如下：
