The UFM block communicates with the logic array similar to LAB-to-LAB
interfaces. The UFM block connects to row and column interconnects and
has local interconnect regions driven by row and column interconnects.
This block also has DirectLink interconnects for fast connections to and
from a neighboring LAB. For more information about the UFM interface
to the logic array, see
Table 2–2
Each MAX II device has four dual-purpose dedicated clock pins
(GCLK[3..0], two pins on the left side and two pins on the right side)
that drive the global clock network for clocking, as shown in
These four pins can also be used as general-purpose I/O if they are not
used to drive the global clock network.
The four global clock lines in the global clock network drive throughout
the entire device. The global clock network can provide clocks for all
resources within the device including LEs, LAB local interconnect, IOEs,
and the UFM block. The global clock lines can also be used for global
