Versal™ device IOs are categorized into the following two categoris:
- It is designed as a high density IO that is cost effective and flexible for implementation. XPIO is designed to replace HPIO ( UltraScale+™ ) and PS dedicated DDR memory interface IO (PS-DDRIO).
- It supports IO standards with maximum VCCO of 1.5V. HDIO is intended to cover IO standards not offered by XPIO with maximum VCCO beyond 1.5V. It is important to define proper IO standard for an accurate on-chip and off-chip power estimation for IO interfaces. If an IO standard is not defined then zero power is reported.
