Tools
Each LAB provides four control signals with programmable inversion
that can be used in all eight LEs. Two of these signals can be used as
clocks, the other two can be used for clear/preset control. The LAB clocks
can be driven by the dedicated clock input pins, global signals, I/O
signals, or internal signals via the LAB local interconnect. The LAB preset
and clear control signals can be driven by the global signals, I/O signals,
or internal signals via the LAB local interconnect. The global control
signals are typically used for global clock, clear, or preset signals because
they provide asynchronous control with very low skew across the device.
If logic is required on a control signal, it can be generated in one or more
LEs in any LAB and driven into the local interconnect of the target LAB.
In addition, the global control signals can be generated from LE outputs.
Logic Element
The LE, the smallest unit of logic in the ACEX 1K architecture, has a
compact size that provides efficient logic utilization. Each LE contains a
4-input LUT, which is a function generator that can quickly compute any
function of four variables. In addition, each LE contains a programmable
flipflop with a synchronous clock enable, a carry chain, and a cascade
chain. Each LE drives both the local and the FastTrack Interconnect
routing structure. Figure 8 shows the ACEX 1K LE.
