Global Clock Networks
Stratix IV devices provide up to 16 GCLKs that can drive throughout the device,
serving as low-skew clock sources for functional blocks such as adaptive logic
modules (ALMs), digital signal processing (DSP) blocks, TriMatrix memory blocks,
and PLLs. Stratix IV device I/O elements (IOEs) and internal logic can also drive
GCLKs to create internally generated global clocks and other high fan-out control
signals; for example, synchronous or asynchronous clears and clock enables.
