The KCU116 XCKU5P FPGA DDR memory interface performance is documented in the
Kintex UltraScale+ FPGAs Data Sheet: DC and AC Switching Characteristics (DS922) [Ref 1].
This memory system is connected to the XCKU5P device HP banks 66 and 67.
The DDR4 0.6V VTT termination voltage (net DDR4_VTT) is sourced from the TI TPS51200DR
linear regulator U35. The connections between the DDR4 component memories and
XCKU5P device banks 66 and 67 are listed in Table 3-2.
