Can I use PSINCDEC to increment the phase shift by more than 1/256 by setting the PHASE_SHIFT value?
Is it possible to increment or decrement the phase shift by more than 1/256 step using Variable Phase Shift?
No. To use the PSINCDEC value, the CLKOUT_PHASE_SHIFT attribute must be set to "VARIABLE". In this mode, the PHASE_SHIFT value is used only as the starting point. After this, the clock will shift by 1/256 only. There is no way to increment the phase shift by PHASE_SHIFT/256.
