Read from a File
To read the contents of a file and load it to the DDR SDRAM, follow these
steps:
1.
Click Load File.
2.
Browse to sample.txt located in the control_panel directory and
click Open. This step instantiates the DDR SDRAM controller and
loads the text contents into the DDR SDRAM. Notice that the Data
to Ascii-text column shows the DDR SDRAM contents in Ascii
value.

1.
Click Save File.
2.

read the DDR SDRAM contents from the start address to the end
address, and write the contents to a file.
