MAX II 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. For input registers, 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.
A dedicated fast I/O connection from the adjacent LAB to the IOEs within an I/O
block provides faster output delays for clock-to-output and t
This connection exists for data output signals, not output enable signals or input
signals.
