The AMD 7 series architecture supported T_DCI standards for bidirectional I/O configurations with 3-state support for internal input split-termination. Those T_DCI standards are not supported in UltraScale devices. However, many of the UltraScale architecture DCI standards are capable of supporting similar bidirectional configurations. Table: T_DCI I/O Standards for Migration between AMD Device Architectures lists the T_DCI standards that are transparently ported or migrated to an equivalent UltraScale architecture standard when designing with the Vivado® Design Suite.
