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...
The logic part of this memory controller is relatively simple. Once the initialization is complete, the core loops and periodically requests a refresh of the SDRAM. Outside that, if the input command FIFO is not empty, the command is read out, and the proper sequence of commands is executed...
2 mig介绍 如上图所示,mig(Memory Interface Solution) IP由三部分组成User Interface Block,Memory Controller和Physical Layer。IP的一边是连接DDR3的接口(Physical Interface),另一边是用户逻辑控制接口(User FPGA Logic)。想要正确的控制DDR3的读写,我们需要正确的设置mig IP和正确的用户逻辑控制接口逻辑。 2.1 mig...

When I try to create the DDR3 Controller IP, I got the following error. My oparating system is Win10 x64 21H2 Build 19044.1466 Quartus Version is 21.1 ( I also got same error with 19.1 and 17.1) Info: drr: Variation language : Verilog Info: ...
1、对FPGA PHY设置 PLL reference clock frequency:FPGA时钟引脚输入的时钟,供DDR的PLL使用时钟频率(关键设置)。工程用27MHZ Full or half rate on Avalon-MM interface: FULL---verilog逻辑部分数据位宽X2,速度/2,,达到了降频的目的(关键设置)。但工程用Half ...
依据DoubleDataRateDDR3SDRAMControllerIPCoreUsersGuide设定自己需要的DDR,不过lattice支持的ddr实在是太少了,所以就选择customer。 仿真的时候,和MIG类似,选定工作目录在sim/modelsim/目录下。 再tool -->tcl -->execute macro 执行do文件 ddr_ipcore_eval.do 。这个ddr_ipcore 是我自己取的IP核的名称 ...
encrypted code, but their functionality (without undocumented MEMORY_DDR3 mode) matches that of Xilinx Virtex 6 devices. So with the simplewrapper modulesthat switch between the *SERDESE2 for synthesis with Xilinx tools and *SERDESE1 for simulation with Icarus Verilog simulator that problem was ...
H All, So, I am trying to get a DDR3 test running on the Nexys Video board was to have one of the example designs that had a mig 7 controller for this board generate an example project. The example project creates a memory traffic controller. This is a X
