2.3.1.3. Global Clock Gating

The dynamic power-down feature is available in GCLK networks only. You can use the power management controller for the dynamic power-down of a GCLK network by controlling the active high enout signal. The GCLK networks serve as low-skew clock sources for functional blocks such as logic array blocks (LABs), DSP, embedded memory, and PLLs.

When a GCLK network is gated, all the logics fed by the GCLK network are in off-state. This reduces the overall power consumption of the device. The dynamic power-down feature allows core logics to control the following power-up and power-down conditions of the GCLK networks:
  • Power down synchronously or asynchronously
  • Power up asynchronously
