1.10.11. 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.
