I am using XC7A200T-2FBG484I Artix -7 FPGA, Hence the speed grade is "-2". that means it will support 800Mb/s DDR3 operation.

 

Correct me if i am wrong.

Hello @patilpradeep,

 

This maximum speed depends on the speed grade of the device which you are using. Please check Table 16 (page #13) from below datasheet to knwo the Maximum Physical Interface (PHY) Rate for Memory Interfaces IP

I need one more help from your end,

 

I am feeling that some problem with IBIS model, Bec when i started simulation for DDR3 Interfaces i am able see results are not proper at the receiver.

And also i checked model performace with 100 ohm load.

 

can we have webex to understand the proble.
