The Stratix II device IOE includes programmable delays that can be
activated to ensure input IOE register-to-logic array register transfers,
input pin-to-logic array register transfers, or output IOE register-to-pin
transfers.
A path in which a pin directly drives a register may require the delay to
ensure zero hold time, whereas a path in which a pin drives a register
through combinational logic may not require the delay. Programmable
delays exist for decreasing input-pin-to-logic-array and IOE input
register delays. The Quartus II Compiler can program these delays to
automatically minimize setup time while providing a zero hold time.
Programmable delays can increase the register-to-pin delays for output
and/or output enable registers. Programmable delays are no longer
required to ensure zero hold times for logic array register-to-IOE register
transfers. The Quartus II Compiler can create the zero hold time for these
transfers.
devices.
The IOE registers in Stratix II devices share the same source for clear or
preset. You can program preset or clear for each individual IOE. You can
also program the registers to power up high or low after configuration is
complete. If programmed to power up low, an asynchronous clear can
control the registers. If programmed to power up high, an asynchronous
preset can control the registers. This feature prevents the inadvertent
activation of another device's active-low input upon power-up. If one
register in an IOE uses a preset or clear signal then all registers in the IOE
must use that same signal if they require preset or clear. Additionally, a
synchronous reset signal is available for the IOE registers.
Double Data Rate I/O Pins
Stratix II devices have six registers in the IOE, which support DDR
interfacing by clocking data on both positive and negative clock edges.
The IOEs in Stratix II devices support DDR inputs, DDR outputs, and
bidirectional DDR modes.
