I/O element Definition
A single register that exists on the periphery of supported device (Arria® series, Cyclone® series, MAX® II , MAX® V, and Stratix® series) families or a bidirectional buffer on the periphery of MAX® II and MAX® V devices. I/O elements can help maximize timing performance, for example, by permitting fast setup times. I/O elements are also known as I/O cells.
The I/O elements in different devices support different I/O standards.
You can assign a logic function to a specific I/O element.
I/O elements have "numbers" of the following format for the following devices:
