  • 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
     以下是log信息
    Info: Generating the Example Design.
    Info: Generating the Pin Planner file.
    Info: Generating the Synopsys Design Constraints file for the example top level.
    Info: Generating the Synopsys Design Constraints file.
    Info: Generating the Timing Report script.
    Info: Generating the ALTPLL Megafunction instance.
    Info: Generating the ALTMEMPHY Megafunction instance.
    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.
    Info: See the User Guide for more details.
