MIG Controller Latency with AXI Interface

Hi,

 

I am doing a determination of a worst-case latency of my design. In my design there is a DDR3 memory controller with an AXI Interface. The only information I find regarding the latency of the DDR3 memory controller is the Answer Record 45644 (https://www.xilinx.com/support/answers/45644.html).

 

Are there more detailed information regarding calculating the latency of the controller? Or can I only use the simulation for determination of the worst-case latency of the DDR3 memory controller?

 

Thanks for helping!

Hi

 

There is no detailed doc with latency values.

 

You need to simulate the MIG core to determine the latency for your configuration and Memory access patterns.

Hi,

 

maybe I am the only one, but to me this lack of information looks like a company is in early stage formation and not like a company more than two decades in business ...
