Hi all,
I have one problem, when I customize the EMIF IP on Arria 10, the Tdivw_total & Vdivw_total should be set following the value in the datasheet of MT40A512M16LY-075, or should be kept following the preset value which provides in the preset example? And in the DDR's data, the Tdivw_total & Vdivw_total are all maximum value, why it's minimum value in the EMIF User guide?
value in datasheet of MT40A512M16LY-075 : Tdivw_total : 0.22UI, Vdivw_total : 120 mv
Value following the preset value : Tdivw_total : 0.20 UI, Vdivw_total : 138mv,
So should I set which value is preferable? Could someone help me and give me some advice?
Brs,
Lambert

Hi Lambert
The Tdivw_total and Tdivw_total parameter slightly differs across the DDR4-2666 bin. Please check the datasheet which you use actually and use the number on the datasheet.
