Accessing 64-bit DDR Memory Location Perform the following to access 64-bit DDR memory location:
1. Change the IP address width to 64-bit in the IP GUI.
2. In Vivado ® address editor, unmap the HP0_DDR_LOW base name which has 0x0000_0000 offset address with 2G band.
3. Auto assign addresses to map DDR_LOW and DDR_HIGH address spaces for 64-bit mode.
4. Vivado will get DDR_HIGH offset address as 0x0000_0008_0000_0000 with 32G band. The IP can use any address as source/destination buffer address.
