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: 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. |
- Generate the design with Qsys
- Connect the pll_ref_clk of IP DDR3 SDRAM Controller with UniPHY on coreclkout of Avalon-MM Cyclone V Hard IP for PCI Express.
- Do all connections you need/want
- Generate the HDL code with Finish button.
- Under Quartus include the file your_project.qip and not your_project.qsys
- Find the file named *_p0_pin_map.tcl :
$ find . -name "*_p0_pin_map.tcl"
- It must be under directory named your_project/synthesis/submodules/
- Edit it and looking for line begin with :
proc qsys_pattern_mem_if_ddr3_emif_0_p0_get_input_clk_id { pll_output_node_id } { if {[qsys_pattern_mem_if_ddr3_emif_0_p0_is_node_type_pll_clk $pll_output_node_id]} { array set results_array [list]
- Change it with this :
[...] proc qsys_pattern_mem_if_ddr3_emif_0_p0_get_input_clk_id { pll_output_node_id } { return $pll_output_node_id if {[qsys_pattern_mem_if_ddr3_emif_0_p0_is_node_type_pll_clk $pll_output_node_id]} { array set results_array [list] [...]
- Find the file named *_p0_pin_map.tcl :
