the 64-bit DDR memory location:
- Change the IP address width to 64-bit in the IP dialog box.
- In the AMD Vivado™
address editor, unmap the
HP0_DDR_LOW
base name which has 0x0000_0000 offset address with 2 G band. - Auto assign addresses to map
DDR_LOW
andDDR_HIGH
address spaces for 64-bit mode. -
Vivado Design Suite gets the
