4.1.8. Clock Power Down
You can power down the GCLK and RCLK clock networks using both static and dynamic approaches.
When a clock network is powered down, all the logic fed by the clock network is in off-state, reducing the overall power consumption of the device. The unused GCLK, RCLK, and PCLK networks are automatically powered down through configuration bit settings in the configuration file (.sof or .pof) generated by the Intel® Quartus® Prime software.
The dynamic clock enable or disable feature allows the internal logic to control power-up or power-down synchronously on the GCLK and RCLK networks, including dual-regional clock regions. This feature is independent of the PLL and is applied directly on the clock network.
