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

 以下是log信息

Info: Generating the Functional Simulation Model for ALTMEMPHY Info: Before compiling your variation in Quartus II, you should follow these steps: Info: - Enable TimeQuest under Settings, Timing Analysis Settings. Info: - Add the alt_ddr2_ip_phy_ddr_timing.sdc file to your Quartus II project. Info: - Add I/O Standard assignments by running the alt_ddr2_ip_pin_assignments.tcl script. Info: - Set the Default I/O standard to match the memory interface I/O standard setting. Info: - Turn on Optimize multi-corner timing in the Quartus II Fitter Settings. Info: - Please make sure that address/command pins are placed on the same edge as the CK/CK# pins. Info: - Set the top level entity of the project to alt_ddr2_ip_example_top.
