怎样调用altera中的ip核

Posted 2023-04-24

参考技术A 如果是QII的IP核，在QII软件中通过Megacore
Wizard加入，就可以了。
如果是第三方的IP核，你应该有他的全部代码。把所有代码都加入到你的工程中，在需要的位置，例化顶层文件，连接好所有的接口，就行。
我想，如果你需要使用这个IP，那么你对这

altera DDR2 ip使用笔记之IP核生成

IP核生成

Quartus生成DDR2 ip流程如下：

点击菜单栏的Tools->MegaWizard Plug-In Manager，弹出

 选择IP类型，保持路径即文件名等，如下图

 点击next，按下图设置：输入时钟50Mhz，DDR驱动时钟150Mhz，Full rate模式，位宽32Bit，器件选择MT47H64M16，与所使用的FPGA开发板一致。

 点next，选择默认即可

 依旧默认

 设置MaxBurstCount为64，

 选择产生仿真模型

 最后点击finish完成

 等待gereration

 完成
