4.2.8.4. Normal Compensation Mode

An internal clock in normal compensation 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 Quartus® Prime Timing Analyzer reports any phase difference between the two. In normal compensation mode, the delay introduced by the GCLK or RCLK network is fully compensated.
