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.
Type
