The Cyclone device IOE includes programmable delays to ensure zero
hold times, minimize setup times, or increase clock to output times.
A path in which a pin directly drives a register may require a
programmable 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 decrease input-pin-to-logic-array and IOE
input register delays. The Quartus II Compiler can program these delays
