For simulation, the DDR3 SDRAM VerilogModel from Micronis used. Import all simulation files under./testbenchto Vivado.ddr3_dimm_micron_sim.svis the top-level module which instantiates both the DDR3 memory controller and the Micron DDR3 model. This module issues read and write requests to the...
本仓库提供了所有模块的Verilog 代码,其中比较关键的模块是AXI写主机、AXI读主机、AXI控制器,这三个模块加上AXI总线 DDR3 MIG IP核,构成了DDR3读写接口。 testbench目录提供了几乎所有子模块的仿真测试文件,wave目录下提供了本工程子模块的简要波形示意图,配合波形图将有助您理解本工程的设计细节。
DDR3 IP核仿真 本文使用 IP 核自动生成的 DDR3 仿真测试激励对 DDR3 的 IP 核进行仿真。如图所示,打开路径...\DDR3_test\DDR3_test.srcs\sources_1\ip\mig_7series_DDR3\ mig_7series_DDR3\example_design\sim下的 sim文件夹,这个文件夹下存放着 DDR3 仿真测试激励。 在Vivado 中右键单击,在弹出菜单...
