External Memory Controller

Hi, I can't seem to find this information anywhere. I need to design a PCB that has a DDR3 memory socket and and FPGA that would interact with the RAM memory plugged into the socket. Now my proble...

Hi Gabe,


I'm Adzim. Thanks for using the Intel Community.


May I know which device that you're used?


Based on your question, do you want to create your own custom memory controller?


"is it possible at all to interface with RAM sticks with different memory timings"

I'm not clear about this. Where is the memory timings here refer to?


Regards,

Adzim

    Hi Adzim,

    Sorry for being ambiguous.

    I am planning to use the Quartus Arria 10 EMIF IP. When I configure the EMIF IP in Qsys, I have to specify the memory timings:

    The problem is: these values are specific to a memory chip. However, I would like to be able to use a range of DDR3 DIMM memory sticks (that might have different memory chips on it, therefore different memory timings) with this EMIF IP. The question is: Does the DDR3 controller provided in Quartus re-adjust the memory timings dynamically, or would I have to regenerate the IP for each memory stick that I plan to use?

    Let me know if this clarified things a bit
