Figure 2–27. Cyclone IOE Structure
Note to
(1)
The IOEs are located in I/O blocks around the periphery of the Cyclone
device. There are up to three IOEs per row I/O block and up to three IOEs
per column I/O block (column I/O blocks span two columns). The row
I/O blocks drive row, column, or direct link interconnects. The column
I/O blocks drive column interconnects.
I/O block connects to the logic array.
I/O block connects to the logic array.
There are two paths available for combinatorial inputs to the logic array. Each path
contains a unique programmable delay chain.
