questasim/modelsim独立仿真vivado ddr3控制器（mig）_questasim vivado2021.1

1.使用场合介绍

当工程中使用DDR做数据缓存时，使用vivado默认仿真器进行功能仿真时速率特别慢，而使用vivado和questasim联合仿真选项虽然能加速仿真（相当于从vivado跳转到questasim进行仿真），但是调试过程中每次修改代码都需要在vivado工具上修改并编译后再跳转到questasim进行波形仿真，流程比较麻烦。本文通过将vivado仿真ddr3控制器所需要的仿真文件扣出来到questasim中进行独立编译仿真。

2.使用vivado联合questasim仿真

为了了解仿真DDR3所需要的文件以及编译流程，先通过vivado跳转到questasim仿真查看编译了哪些文件。

2.1搭建仿真环境

2.1.1导出mig仿真例程

根据自己板子的ddr3芯片型号和使用需求生成mig,本文将mig ip核生成名为ddr3，勾选AXI4 Interface选项,在source框右击ddr3,选择Open Ip Example Design...选项，创建仿真工程ddr3_ex。

仿真工程生成好后找到ddr3_ex文件夹路径下imports文件夹，导入ddr3_model.sv,ddr3_model_parameters.vh,wiredly.v到自己工程目录下，并将sim_tb_top.v中的example_top换成自己需要仿真的顶层文件。最终如下图所示

2.2.2设置vivado仿真工具

点击Tools->setting

修改如下设置

点击Run Simulation跳转到questasim进行仿真，如下图所示

 仿真波形

2.2.3 查看仿真流程

进入工程路径下XX.sim->sim_1->behav->questa，有三个脚本可执行文件compile.bat,elaborate.bat和simulate.bat。分别代表仿真的三个步骤：综合，优化，执行仿真。

compile.bat：综合脚本，对源文件进行综合。脚本调用了DDR_AXI_tb_compile.do

打开questasim执行仿真脚本，结果与vivado联合questasim仿真结果一致

3.1在transcript命令行中cd到脚本文件路径下

3.2 source脚本文件，并执行build编译源文件

3.3 rerun,启动波形仿真

波形界面

4.注意事项

4.1 MEM_BITS

*如果需要仿真的地址空间太大需要修改ddr3_parameters.vh文件中的MEM_BITS，否则会报ERROR： Memory overflow. Write to Address 7000fe with data xxx will be lost You must increase the MEM_BITS parameter of define MAX_MEM.

MEM_BITS定义了ddr3_model.sv中地址位宽，默认为15
    在ddr3_parameters.vh文件中, 根据需要扩充MEM_BITS参数，比如修改至20。
