Zynq Ultrascale+ XCZU15EG-FFVB1156 DDR4 DRAM 80 bit fly-by layout example

Jump to solution
Hello Thank you for reading my question. I am looking for a DDR4 layout example for my FPGA or a similar one. I will use 5 pieces of x16 DDR4 DRAM memories in fly-by configuration and I have so far only found layout examples for DDR4 DIMM. I would prefer the layout for the FFVB1156 package (I guess it is the same layout for all devices using FFVB1156 package), but any package with similar layout will help me with my design. I would prefer some native layout format (Cadence, Mentor, Allegro, etc) or gerber rather than pdf. Best regards //Jacob Rengman

Hi,

 

I'm not sure you'll find a lot of examples... But, you can look at the zcu102 & zcu106 DDR4 PL routing.

Less ddr4 memories but it could give you some hint.

 

We did researches on the internet for layout guidances but we also used the guidelines from Xilinx UG583 to extract our layout constraints.
