An internal clock in normal mode is phase-aligned to the input clock pin. The external clock output pin has a phase delay relative to the clock input pin if connected in this mode. The Intel® Quartus® Prime software timing analyzer reports any phase difference between the two. In normal mode, the PLL fully compensates the delay introduced by the GCLK network.
