GDDR5X with Xilinx FPGA

Is it possible to use GDDR5X memory with Xilinx FPGA, for example with Ultrascale family?

Re: GDDR5X with Xilinx FPGA

We don't have any solution for GDDR5X memory. You may need to develop your own based on interface requirement

What do you mean by "your own based on interface requirement" ?

Is it possible somehow to use GDDR5X with your FPGAs?

Re: GDDR5X with Xilinx FPGA

we don't have controller for GDDR5X memory however in my understanding GDDR5 are based on DDR3 SDRAM memory which is supported by Xilinx . you may required to write your own controller

Re: GDDR5X with Xilinx FPGA

What are the current limits for GDDR5X different signal types? I do not see any info about current ratings at GDDR5X datasheet..

Re: GDDR5X with Xilinx FPGA

I think that is the way that it should be. But somehow if ti does not work then we have to write separate program.

The link below shows  Achronix FPGA with Micron's GDDR6. I also see that NVDIMM-N - integration of DIMM, FPGA and 3D -NAND should be more promulgated . I am yet to see the comparison of 3D XPoint optane with NVDIMM-N.

But GDDR5X with Xylinx FPGA should offer drivers.
