altera 提供了很多的IP核，在开发FPGA项目时候可以大大提高效率，但是网上的证书只有NIOS II 的授权。如何获取全部授权呢？
其实很简单，打开license.DAT
应该是这样：
FEATURE quartus alterad 2037.12 permanent uncounted 385FB2185EE1
HOSTID=002219074965 TS_OK SIGN="1113 5A52 EA34 2C59 C5B7 B031

#license文件存放的路径名称不能包含汉字和空格，空格可以用下划线代替。
#把license.dat里的XXXXXXXXXXXX用您老的网卡号替换(在Quartus II的Tools菜单下选择License Setup，下面就有NIC ID)。
假设 我需要三速以太网 triple speed ethernet
在编译的时候，quartus 会告诉你 这个IP核的特征字，如下：
Warning: OpenCore Plus Hardware Evaluation feature is turned on for the following cores
Warning: ""Triple Speed Ethernet" (6AF7_00BD)" will use the OpenCore Plus Hardware Evaluation feature
Warning: Messages from megafunction that supports OpenCore Plus feature
Warning: Messages from megafunction that supports OpenCore Plus feature TSE_MAC
Warning: The Triple Speed Ethernet MegaCore MAC function will be disabled after time-out is reached
Warning: Megafunction that supports OpenCore Plus feature will stop functioning in 1 hour after device is programmed
那么 修改上面的证书 ，如下：
这个就是三速以太网的证书，试试吧！
