I trying to design a board using the reference design of ALTERA cyclone V, I found many DNI components (resistors and capacitor), what i have to do with this components?, opened circuit?
In the LPDDR2 schematic there are singal CK and CK# (clocks) have a resistor DNI between them, besides in this schematic i saw DQ[0..31] (data port ) have connected the DQ[16..31] connected to ground by resistors DNI? thanks in advanceLink Copied

Hi Akael:
DNI stands for Do Not Install: These components may have been placed on the schematic for many reasons. IE your DQ lines are probably because one version of the schematic only supported a 16 bit memory, while another supports the full 32 bit interface. The CK and CK# resistor is probably for termination. If you are confident you know what the resistor position is there, you can safely remove them from your schematic. Pete- Mark as New
