.tcl code to read and write into DDR memory in Arria-V-GT

Hi,

I am trying to read and write data ( Hex files in .txt format) into DDR memory of Arria V GT series FPGA.

However I want to have .tcl code which I can control using MATLAB etc, without compiling part of the project.

Main motivation is that, I am currently using internal memory where it seems that I can write only 2^16 data and I would like to be able to send more data.

I will really appreciate if anyone can provide .tcl code to read and write from DDR memory, or even may be

guideline to write such a code.

Please consider me a novice in FPGA coding while replying.

Best Regards,

Meenakshi
