hi
I want to measure the maximum speed of read/write of my memory. I have a microblaze processor and a sdram in my design. I'm going to add a dma in order to write to memory. do you have any better idea? I can't find any good source or example for dma. could you please tell me, what should I do??
Thanks.
 

Your can know the maximum supoprt of the sdram from its vendors.
In your design, you can check it by clock supplied to the sdram.

Why do you need a dma ?
 
thanks for the comment slutarius. in fact I want to test my pcb, I am not sure that my pcb works correctly at high frequency.
do have any idea?

So the issue is different from what you started.
I have nothing to say about PCB here. Sorry.

thanks for the comment. my target frequency is 1600 MHz.

Your design look like to have 2 problems regarding to that frequency. One is the Timing of internal FPGA and the other one is IO Timing.
For IO, you can search for some range, or technique to due with high frequency signal.
