Combined Resources
Within each quadrant, there are 24 distinct dedicated clocking resources consisting of
16 global clock lines and eight regional clock lines. Multiplexers are used with these
clocks to form buses to drive LAB row clocks, column IOE clocks, or row IOE clocks.
Another multiplexer is used at the LAB level to select three of the six row clocks to
feed the ALM registers in the LAB (refer to
You can use the Quartus II software to control whether a clock input pin drives either
a GCLK, RCLK, or dual-RCLK network. The Quartus II software automatically selects
the clocking resources if not specified.
