I'm developer FPGA's design but right now I wanna learn to develop designs with DDR3 SDRAM Memory. Does anyone know where I can get started?
You can get started with generating the example design from the IP parameter editor first, and work with that design to get an idea of how everything should work by referring to this chapter 13.3 (Uni-PHY Based Example Design) of the external memory handbook:
You can also check out this online training. It's older, but still completely applicable:
Hope this helps.
