Stratix Device Handbook, Volume 2
The DSP block interface generates the clock signals from LAB row clocks
or the local interconnect. The clear signals are generated from the local
interconnects within each DSP block row interface or from LAB row
clocks. The four clock enable signals are generated from the 30 local
interconnects from the same LAB rows that generate the clock signals.
The clock enable is paired with the clock because the enable logic is
implemented at the interface.
