MAX V device IOEs contain a bidirectional I/O buffer.
IOE structure. Registers from adjacent LABs can drive to or be driven from the IOE’s
bidirectional I/O buffers. The Quartus II software automatically attempts to place
registers in the adjacent LAB with fast I/O connection to achieve the fastest possible
clock-to-output and registered output enable timing. When the fast input registers
option is enabled, the Quartus II software automatically routes the register to
guarantee zero hold time. You can set timing assignments in the Quartus II software
to achieve desired I/O timing.
