Figure 2–42. Conditional Operation Example
The arithmetic mode also offers clock enable, counter enable,
synchronous up and down control, add and subtract control,
synchronous clear, synchronous load. The LAB local interconnect data
inputs generate the clock enable, counter enable, synchronous up and
down and add and subtract control signals. These control signals may be
used for the inputs that are shared between the four LUTs in the ALM.
The synchronous clear and synchronous load options are LAB-wide
signals that affect all registers in the LAB. The Quartus II software
automatically places any registers that are not used by the counter into
other LABs.
