we are facing an issue while using ddr3 mig on kintex .init calib done signal is going high ,but while reading the data from DDR3 the we are seening that the same data is repeating with different address.
for example for address 1 ,2,3,4 we are writing the data 1,2,3,4 but while reading the address 1,2,3,4 we are getting the data as 1,2,2,4 .
is there any solution for this issue

Please notice the write operation will be issued when app_en=1 and app_rdy=1. Is the app_addr=xxx0h, xxx8h, xx10h, etc for write and read operation?

yes, and while writing we are checking for wdf_rdy and we are not reading and writing at the same time. we are writing big chunk of data and then reading it back
