Xilinx provides I/O Buffer Information Specification (IBIS) models for all supported I/O standards in FPGA and MPSoC devices.

This blog entry provides a guide on how to decode an IBIS model name for both Programmable Logic (PL) and Processing System (PS) Multipurpose I/O (MIO).  This has been broken down into three sections.  

1. PL I/O Standards
2. PS MIO Standards
3. PS DDR I/O Standards
