1.10.248. PHYSICAL_SYNTHESIS_ASYNCHRONOUS_SIGNAL_PIPELINING

Specifies that Quartus Prime 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. This feature is not supported in Quartus Prime Pro Edition.
