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"
