The VCU118 dual DDR4 80-bit memory component interfaces adhere to the constraints
guidelines documented in the "DDR3/DDR4 Design Guidelines" section of the UltraScale
Architecture-Based FPGAs Memory IP LogiCORE IP Product Guide (PG150)
VCU118 board DDR4 memory component interface is a 40Ω impedance implementation.
