AMD Versal™ device IOs are categorized into the following two categories:
- HDIO
- It is designed as a high density IO that is cost effective and flexible for implementation. HDIO is intended to cover IO standards not offered by XPIO with maximum VCCO beyond 1.5V.
- XPIO
- It supports IO standards with maximum VCCO of 1.5V. XPIO is designed to replace HPIO (AMD UltraScale+™ ) and PS dedicated DDR memory interface IO (PS-DDRIO). 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.
