Figure 5–2. RCLK Networks (EP4SE230, EP4SGX70, and EP4SGX110 Devices)
Note to
(1) A maximum of four signals from the core can drive into each group of RCLKs. For example, only four core signals can drive into RCLK[0..5] and
Stratix IV Device Handbook Volume 1
another four core signals can drive into RCLK[54..63] at any one time.

Regional Clock Networks
5–2:
RCLK networks only pertain to the quadrant they drive into. RCLK networks provide
the lowest clock delay and skew for logic contained within a single device quadrant.
The Stratix IV device IOEs and internal logic within a given quadrant can also drive
RCLKs to create internally generated regional clocks and other high fan-out control
signals; for example, synchronous or asynchronous clears and clock enables.
