Altera Quartus II Settings File - Manual (Page 922)

PROPAGATE_INVERSIONS_ON_INPUTS
Specifies that the Compiler should push inversions into partition inputs when possible. This cross-
boundary optimization is especially important when inverted clock or asynchronous signals are
connected to a partition input. Without this optimization, the Compiler may need to implement the
inversion with a logic cell, introducing skew on the clock or reset path. The partition must also have
enabled cross-boundary optimizations with the CROSS_BOUNDARY_OPTIMIZATIONS assignment.
