Introduction

2 RAMs are connected to CycloneV's APF6_SP.

Parameters

  • DDR3:
MT41K128M16JT-125
part MT41K128M16JT-125
type DDR3L
Speed 750Mhz
timings See verilog model provided by micron
JEDEC JEDEC DDR3-1600 -> JEDEC DDR3-1G6 2GB x8
Chip size 2048Mbits -> 128M x 16bits

Diagram above describe the connections between the CycloneV and the two DDR3 blocks. Each DDR3 blocks has two banks of 128MB, on one chip (U15) all data are used, and on the other chip, only 128MB are used, the second bank is not plugged. Thus, the amount of ram accessible via the fpga is 384MB, with a data bus of 24bits.

To use the DDR3 SDRAM Controller with UniPhy provided by Quartus to instanciate the DDR3. See above how to do with Qsys.

Clock

The hard controller IP «DDR3 SDRAM Controller with UniPHY» require using and external oscillator to clock it. On APF6_SP, the all CycloneV fpga is clocked with the PCIe clock at 125Mhz by default.

To force Quartus to use the coreclkout as input clock for DDR3 controller a little hack must be done after HDL code is generated.

The DDR3 clock hack

Note Note: If you include the .qsys under your Quartus project, Quartus will regenerate all the Qsys HDL/TCL code each times you synthesize your design, and will erase the modification.
  1. Generate the design with Qsys
    1. Connect the pll_ref_clk of IP DDR3 SDRAM Controller with UniPHY on coreclkout of Avalon-MM Cyclone V Hard IP for PCI Express.
    2. Do all connections you need/want
    3. Generate the HDL code with Finish button.
  2. Under Quartus include the file your_project.qip and not your_project.qsys
    1. Find the file named *_p0_pin_map.tcl :
      $ find . -name "*_p0_pin_map.tcl"
    2. It must be under directory named your_project/synthesis/submodules/
    3. Edit it and looking for line begining with : 
      proc YOUR_PROJECT_NAME_mem_if_ddr3_emif_0_p0_get_input_clk_id { pll_output_node_id } {
    4. Add this line at the begining of function :
      return $pll_output_node_id
    5. Then synthesize all.
Note Note: In one line :
$ find . -name "*_p0_pin_map.tcl" | xargs sed -iolt "/_mem_if_ddr3_emif_0_p0_get_input_clk_id {/a     return \$pll_output_node_id"
