I need to Test my Controller which cannot synthesize at higher than 100-120 MHz and does only fit in a STRATIX10. I Imagine i should start the DDR4 at normal speed and then have some logic to set it in DLL-off mode before i let the controller take charge.
I do not see the DLL-off mode to be documented anywhere in the EMIF docs, so i would like to know if this is something that is even supported and if there is a risk trying to do this?
