The Stratix device IOE includes programmable delays that can be
activated to ensure zero hold times, input IOE register-to-logic array
register transfers, or logic array-to-output IOE register 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 combinatorial 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
