Board Component Descriptions
The VCU118 RLD3 72-bit memory component interface adheres to the constraints
guidelines documented in the RLD3 Design Guidelines section of
UltraScale
Architecture-Based FPGAs Memory IP LogiCORE IP Product Guide
(PG150)
. The
VCU118 RLD3 memory component interface is a 40
Ω
impedance implementation. For more
information on the internal VREF, see the "Supply Voltages for the SelectIO Pins", “V
REF
”,
and “Internal V
REF
” sections in
UltraScale Architecture SelectIO Resources
(UG571)
