How to Test Ram Speed With Kintex-7

[strahd_von_zarovich]

Hi Everyone,
I've designed a FPGA board. There are 4 DDR3L RAM ICs on the board and I want to test RAM communication speed. What is the proper way to do it?

Thanks in advance.

The few DDR cores I've worked with from FPGA vendors in the past usually have a synthesizable testbench that you can implement in your FPGA that does a RAM test of some sort.

If the IP doesn't include something like that, just build a simple processor system with DDR and run a RAM test using standard memory test C code running on the embedded processor.

@strahd_von_zarovich
I see that you are using K7 and DDR3 memory.
So definitely you will need to use the MIG IP core.
The good news is, as mentioned above, there is help from Xilinx.

Search for old threads within the Xilinx/AMD forum to know how others have done it.
