For two systems to share the same memory, an arbiter must be used. The memory arbiter serves as an interface to both systems, and grants each system access to the memory one at a time to avoid collisions. In this project, Teradyne assigned the MQP team the task of developing a memory ...
点击Flow Navigator 面板下的“Project Manager -->IP Catalog”。 在“Memories & Storage Elements --> Memory Interface Generators”分类展开后,可以看到名为“Memory Interface Generator (MIG 7 Series)”的 IP 核,通过这个 IP 核,我们可以配置一个 DDR3 控制器用于衔接 FPGA 逻辑与外部 DDR3 存储器。点击...
It should be noted that the same project using the Xilinx MIG DDR3 controller takes 33% of the FPGA LUTs (vs 9% with this core). Testing Verified under simulation, then exercised on the following FPGA boards; Digilent Arty A7 (Xilinx Artix + MT41K128M16JT-125) ...
FPGA厂家都会提供内嵌逻辑分析仪,Xilinx叫chipscope,Lattice的叫reveal,可以单独安装reveal程序,也可以在diamond工程中打开。在“File List”的“Debug Files”里,右键,点击Reveal Project Files,可新建*.rvl文件,相对Xilinx,这个rvl比较好用,复制veriog代码信号名,只要没被优化,就可以很快找到。 添加信号时,除了在trace ...
1,111 Views Hey guys, I am a newbie to Quartus and I am doing a project on the DE4 board wherein I need to store lots of values in the external memory. So i have been looking into the DDR2 memory controller implementation. What i found out that the IP core for the controller ...
memory controller. The IP walks through all permissible values for write leveling and delay compensation and then exports a table with possible values that the designer can use for optimal DDR performance or environmental constrained configurations. This code is ready to run within the On-Chip ...

(1)打开Quartus,点击File → Open Project,打开刚才生成的仿真文件:generate_sim_example_design.qpf (2)选择Tools → Tcl Scripts,点击generate_sim_verilog_example_design.tcl,click "Run"即可。 (3)打开modelsim,切换目录:xxx/simulation/verilog/mentor ...
而Zynq系统的这个DDR总线接口有是链接在其内部“Memory Interfaces”中的“DDR2/3,LPDDR2 Controller”可配置硬核上的。 因此,要想PL访问板上的DDR3存储器,必须借道Zynq中的“Memory Interfaces---DDR2/3,LPDDR2 Controller”(后文简称“DDR3 Controller”)。根据之前的经验,在Zynq系统中,ARM Core(CPU)能够访问...
This means, that I wanted to access the DDR memory chip through just the DQ/DQS groups only and not instantiate a full-blown memory controller using the megafunction. I quickly learnt that it wasn't so straight forward as it looked. I started off with a clean projec...
