Altera Quartus II Settings File - Manual (Page 442)

AUTO_DELAY_CHAINS_FOR_HIGH_FANOUT_INPUT_PINS
Allows the Fitter to choose how to optimize the delay chains for high fanout input pins. You must enable
the Auto Delay Chains option for this option to work. Enabling this option may reduce the number of tsu
violation, but the compile time increases significantly, as the Fitter tries to optimize the settings for all
fanouts.
