Description
IO_STANDARD objects define the available IOSTANDARDs supported by the target AMD device. The IO_STANDARD object can be assigned to PORT objects through the IOSTANDARD property to configure input, output, or bidirectional ports in the current design. For more information on supported standards, refer to 7 Series FPGAs SelectIO Resources User Guide (UG471) and UltraScale Architecture SelectIO Resources User Guide (UG571).

You can query the IO_STANDARD associated with specific BELs, SITEs, PACKAGE_PINs, IO_BANKs, or PORTs of interest:
get_io_standards -of [get_ports ddr4_sdram_dm_n[0]]You can also query the PORT objects that implement a specific IO_STANDARD:
get_ports -of [get_io_standards POD12_DCI]get_ports
-filter {IOSTANDARD==POD12_DCI}.Properties
