FLEX 10KE Embedded Programmable Logic Devices Data Sheet
Figure 1 shows a block diagram of the FLEX 10KE architecture. Each
group of LEs is combined into an LAB; groups of LABs are arranged into
rows and columns. Each row also contains a single EAB. The LABs and
EABs are interconnected by the FastTrack Interconnect routing structure.
IOEs are located at the end of each row and column of the FastTrack
Interconnect routing structure.

FLEX 10KE devices provide six dedicated inputs that drive the flipflops’
control inputs and ensure the efficient distribution of high-speed, low-
skew (less than 1.5 ns) control signals. These signals use dedicated routing
channels that provide shorter delays and lower skews than the FastTrack
Interconnect routing structure. Four of the dedicated inputs drive four
global signals. These four global signals can also be driven by internal
logic, providing an ideal solution for a clock divider or an internally
generated asynchronous clear signal that clears many registers in the
device.
