2.5.11. SDM Shared I/O Requirements

The Avalon® streaming interface ×16 configuration modes use the configuration pins located in an HSIO bank for device configuration. The VCCIO_PIO voltage rail, instead of the VCCIO_SDM voltage rail, powers the HSIO bank.

When you use Avalon® streaming interface ×16 configuration scheme, Avalon® streaming interface pins in the SDM shared IO bank are not usable as user I/Os for:

  • Designs that use external partial reconfiguration, for example, designs that send partial reconfiguration bitstream using Avalon® streaming interface pins.
  • Designs that use the HPS.
