Altera Quartus II Settings File - Manual (Page 673)

PHYSICAL_SYNTHESIS_ASYNCHRONOUS_SIGNAL_PIPELINING
Specifies that Quartus II should perform automatic insertion of pipeline stages for asynchronous clear and
asynchronous load signals during fitting to increase circuit performance. This option is useful for
asynchronous signals that are failing recovery and removal timing because they feed registers using a
high-speed clock.
Type
