A design should not contain any delay chains, which are two or more consecutive nodes with a single fan-in and a single fan-out that are used to cause delay. Delay chains often result from asynchronous design practices and can cause various design problems, including an increase in a design's sensitivity to operating conditions, a decrease in a design's reliability, and difficulties when migrating a Quartus^® II device to a HardCopy^™ device.
