DDR3B/C for FPGA 2
The development board supports a 16Mx64x8 bank DDR3 SDRAM interface on
FPGA 2 for very high-speed sequential memory access. The 64-bit data bus consists of
four x16 devices with a single address or command bus. This interface connects to the
vertical I/O banks on the top edge of the FPGA.
This DDR3 SDRAM has two interface options. The first option is a x32 interface using
a memory hard controller. The second option is a x64 interface using a memory soft
controller.
lists the DDR3B (x32 hard controller) pin assignments, signal names, and
functions. The signal names and types are relative to the Arria V GT FPGA in terms of
I/O setting and direction.
