The XQ ruggedized UltraScale+ devices have some combination of HP I/O and HD I/O. The Defense-Grade UltraScale Architecture Data Sheet: Overview (DS895) lists these resources by device and package. See UltraScale Architecture SelectIO Resources User Guide (UG571) for details on HD I/O and HP I/O.

When the device is in LVAUX mode, each HP I/O pin that is used in the design must be configured to use one of the 1.2V LVAUX I/O standards listed here:

  • LVCMOS12_LVAUX
  • SSTL12_LVAUX
  • DIFF_SSTL12_LVAUX
  • AIO12_LVAUX
  • DIFF_AIO12_LVAUX
  • LVDS12_LVAUX
  • MIPI_DPHY_LVAUX
Note: System monitor external analog inputs (I/O standard = ANALOG or ANALOG_SE) are not supported in LVAUX mode HP I/O banks. Instead, if HD I/O are available in the device, consider routing external analog inputs through an HD I/O.
