PLL_OPTIMIZE_PHASE_SHIFT_FOR_TIMING
Allows the Fitter to set the phase shift of a PLL output counter, and hence the phase shift of its generated clock, to improve timing for all edges affected by this clock. Apply multicycle timing exceptions to paths between the generated clock and other clocks in the design to avoid timing violations.
